high afp levels in pregnancy

It is optimal to test MS between 16 and 18 weeks. 17–1). Baby Bath Thermometers – Types, Usage and Tips to Choose the... To check for brain and spinal problems in the unborn child, You have a family history of birth defects. Outside of pregnancy and birth, liver damage and certain cancers can increase AFP levels significantly. Parenting.Firstcry.com accepts no liability for any errors, omissions or misrepresentations. Normal Alpha-Fetoprotein. Wrap an elastic band around the intended spot, usually on the upper arm, so that the vein is easy to find. There is an Afro‐Caribbean effect on serum AFP, which is dependent on gestational age, whereby relative serum AFP levels are high at early gestations and low at late gestations. At the end of the first trimester, it is present in the fetal serum in milligram quantities, and in the amniotic fluid in microgram quantities, and in the maternal serum in quantities measured in nanograms. Among women with elevated AF-AFP, approximately one third of fetuses are anomalous.18 Similar to MS-AFP, the likelihood of a neural tube or other defect increases proportionately with the degree of AF-AFP elevation, but clearly not all of these fetuses will be abnormal. These included 710 NTDs (417 anencephaly, 247 spina bifida, and 46 encephalocele), 286 ventral abdominal wall defects, 163 fetuses with Down syndrome, and 231 cases of other chromosomal anomalies. 17–2, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window), Click to share on Google+ (Opens in new window), on Pregnant Women with High Maternal Serum–Alpha-Fetoprotein, 17 Pregnant Women with High Maternal Serum–Alpha-Fetoprotein. Remove the elastic band from your arm after blood has been drawn. High levels of AFP may also suggest defects with the esophagus or failure of your baby’s abdomen to close. It would be ideal if a single MS-AFP level could completely segregate normal from abnormal fetuses. Some dysplastic “brain tissue,” representing angiomatous stroma, may be observed above the orbits, apparently floating freely in the amniotic fluid. Less common defects include fetal teratoma (pharyngeal, sacral), defects caused by the amniotic band syndrome (asymmetric cephaloceles, gastropleuralschisis), cystic hygroma, lesions that alter the placentomaternal barrier (e.g., placental chorioangioma, lakes, and abruption/hemorrhage), proximal fetal gut obstructions (e.g., esophageal and duodenal atresias), some renal abnormalities, and oligohydramnios.39 Thus, careful examination of the face, posterior neck, oropharynx, thorax, abdomen (including a normally filled stomach) should be performed.40 The limbs and digits should be assessed for abnormalities suggesting the amniotic band syndrome or the vertebral, anorectal, cardiac, tracheoesophageal fistula, renal, and limb (VACTERL) anomalies association. Thus, the choice of a judicious cutoff value that maximizes detection of anomalies and minimizes the number of false-positive results is necessary for this screening program to be effective. An AFP tumor marker test is a blood test that measures the levels of AFP … Unfortunately, this is impossible owing to considerable overlap in MS-AFP levels between normal and abnormal pregnancies. AFP stands for alpha-fetoprotein. MOMS are typically corrected for maternal weight, race, and diabetes. A myelomeningocele is suggested by a defect in the normal smooth dorsal skin line and splayed posterior ossification centers on the transaxial image (Fig. You might also be asked to provide details about the race, age, and the number of weeks you have been pregnant for. Elevated serum AFP levels occur in 70% of nonpregnant patients with hepatocellular carcinoma. Abnormal levels of AFP can indicate several problems. What is Down syndrome? In non-pregnant adults (males and females) the high value of Alpha-FetoProtein indicates the danger of cancers related to testicles, … MS levels are usually reported in multiples of the median (MoM) to standardize interpretation among laboratories. Using this cutoff, ~90% of anencephalic fetuses, 75 to 80% of fetuses with an open spinal defect, 98% of fetuses with gastroschisis, and ~70% of fetuses with omphaloceles will be detected.11 Further, using 2.5 MoM as the cutoff has resulted in a reasonably low screen-positive rate (~4 to 5%). AFP levels are usually high when a baby is born, but fall to very low levels by the age of 1. does anyone know this doc or … Such mothers are at very low risk of giving birth to a child with neural defects. The fetus has omphalocele complications. Healthy adults should have very low levels of AFP. The baby's intestines are outside the abdomen (belly). The normal range of AFP values can vary somewhat, depending on the lab you go to. Because the most commonly encountered defects are those of the neural tube and ventral abdominal wall, the neural axis and ventral abdominal wall will be the most critical regions for scrutiny during the targeted sonogram. 2004 Aug;22(3):227-34. doi: 10.1055/s-2004-831898. In some cases, the precise mechanism for the fetomaternal transfer is not known (proximal gut obstruction, renal agenesis), and may be secondary to diminished fetal gut degradation or elevated fetal serum concentrations of AFP. 2.6 is 2.6 times the average amount. A pregnant woman's AFP levels decrease soon after birth. Roughly 6 to 15% of women with high MS-AFP have some type of major congenital defect, and this risk increases with the magnitude of MS-AFP elevation.2,13,14. It would be ideal if a single MS-AFP level could completely segregate normal from abnormal fetuses. High levels of AFP may also suggest defects with the esophagus or failure of your baby’s abdomen to close. You are a smoker, which can cause higher levels of AFP in the blood. Detectable quantities of AFP in the MS gradually increase during gestation, peaking at 30 to 32 weeks and declining thereafter. In normal pregnancies, AFP from fetal serum enters the amniotic fluid through fetal urination, fetal gastrointestinal secretions, and transudation across fetal membranes (amnion and placenta) and immature epithelium. Among the first 1.1 million women screened through the California AFP Screening Program, 1390 fetal anomalies (morphological and chromosomal) were detected (prevalence of 1.3/1000). Detectable quantities of AFP in the MS gradually increase during gestation, peaking at 30 to 32 weeks and declining thereafter. However, it can also be useful for adults who arent pregnant. Pregnancy is associated with elevated AFP levels, particularly if the pregnancy is complicated by a spinal cord defect or other abnormality: Maternal serum AFP test results, interpreted according to the gestational age, are often reported in terms of multiple of the median (MoM). Accurate dating is critical for AFP screening because serum AFP levels rise ~15% per week during the 16 to 18 week window. She had a scan and was told all looked well, not to worry. When we included only women in whom AFP was elevated in isolation, there was no association with preterm birth (OR=1.80, 95%CI: 0.92-2.68). The baby might have an abdominal wall defect, a condition wherein the intestines or other organs are located outside the body. Alpha-fetoprotein (AFP) screening was shown to be effective for detecting neural tube defects (NTDs) in the 1970s.1In 1991, the American College of Obstetrics and Gynecology (ACOG) endorsed offering maternal serum (MS)-AFP testing to all pregnant women. Down syndrome is a common birth defect occurring in about one in every 700 babies. Expected rates of sonographic detection for neural tube and abdominal wall defects are currently > 90%.21–27 It is estimated that a complete, detailed, normal sonogram can now reduce the MSAFP-based risk of a neural tube or ventral abdominal wall defect by 95%.28,2 Second, going directly to a targeted sono-gram circumvents the small, but important procedural risk of fetal loss from amniocentesis. It is usually conducted in the second trimester of pregnancy as part of the triple screen or quad screen. As a result, women with elevated MS-AFP have, in increasing numbers, opted to go directly from the serum AFP test to a targeted fetal sonogram, skipping the amniocentesis. Using this cutoff, ~90% of anencephalic fetuses, 75 to 80% of fetuses with an open spinal defect, 98% of fetuses with gastroschisis, and ~70% of fetuses with omphaloceles will be detected.11 Further, using 2.5 MoM as the cutoff has resulted in a reasonably low screen-positive rate (~4 to 5%). AFP goes through the placenta into the mother's blood. The ventral abdominal wall of the fetus is examined, with focused attention on the umbilical cord insertion. Diseases such as mononucleosis and cytomegalovirus, which can be harmful to a fetus, can also cause rises in A… AFP is present in the fluid around the fetus (amniotic fluid) and a small amount crosses the placenta and moves into the mother's blood stream. Healthy adults should have very low levels of AFP. The spine should be carefully examined in each fetus, including segment by segment images in the transaxial and sagittal planes from the craniocervical junction through the sacrum. Maternal serum reaches its peak at the 13th week of gestation, then declines rapidly to <2% of the maximum level by 34 to 36 weeks of pregnancy. An AFP level between 10 ng/mL to 20 ng/mL is normal for adults. AF-AFP testing is a highly sensitive method for detecting or excluding NTDs. Normal. An AFP tumor marker test is a blood test that measures the levels of AFP in adults. In rare cases, the vein may swell up resulting in a condition called phlebitis, which can be treated with a warm compress applied at regular intervals. AFP goes through the placenta into the mother's blood. An alpha-fetoprotein (AFP) blood test checks the level of AFP in a pregnant woman's blood. There are almost no risks associated with an AFP test. High levels of AFP can indicate an increased chance of the fetus having a neural tube defect such as spina bifida. As a result, women with elevated MS-AFP have, in increasing numbers, opted to go directly from the serum AFP test to a targeted fetal sonogram, skipping the amniocentesis. The negative predictive value of a normal AF-AFP is ~97 to 99%, and elevated AF-AFP plus acetylcholinesterase allows > 99% accurate detection of NTDs.19,2 The specificity is 94.9%.20 High-resolution, targeted ultrasonography performed in conjunction with abnormal AF-AFP is also highly accurate in identifying anomalous fetuses (i.e., > 99% accurate).18,2. In one study, either high or low MSAFP was associated with 34% of all major congenital defects. If the AF-AFP is elevated (≥ 2.0 MoM), a targeted fetal sonogram (level 2) is offered. Some have cautioned against adopting a routine policy of circumventing the amniocentesis because (1) this approach will require a much larger number of targeted sonograms (i.e., 10 times as many), and the larger number of experienced examiners may not be available, or patients may be required to travel a long distance for the targeted sonogram; (2) even experienced examiners, especially as the prevalence of defects falls in the population scanned, may not detect as many defects as AF-AFP testing; and (3) skipping amniocentesis will cause potentially detectable chromosomal abnormalities to be missed.23,2 The last issue remains controversial, and multicenter consensus has not been reached. Levels of AFP are usually normal in the amniotic fluid of a majority of women who have abnormal AFP blood levels. California implemented a statewide screening program in 1986. The normal curvature of the spine should be documented, and the ossified posterior elements examined for abnormal splaying. An extremely high level of AFP in your blood—greater than 400 ng/mL—could be a sign of liver tumors. The intent of a standard antepartum obstetrical sonogram is to provide a general assessment of fetal/pregnancy health; it is performed according to the published guidelines endorsed by the American Institute of Ultrasound in Medicine (AIUM), ACOG, and American College of Radiology (ACR).15 The standard antepartum obstetrical sonogram is an important step in the triage of patients with high MS-AFP; impressively, approximately 20 to 50% of the elevated MS-AFP levels will be explained by findings on this preliminary sonogram (including the detection of a number of neural tube and abdominal wall defects).16,2 If the elevated MS-AFP is not explained by findings of the standard antepartum obstetrical sonogram, traditionally, the next step has been to counsel patients and offer amniocentesis for measurement of amniotic fluid (AF)-AFP. About 90 percent of all pregnancies with open neural tube defects will be identified through AFP PLUS testing. Anencephaly can be diagnosed in virtually all affected fetuses after 14 weeks gestation.42, Since the 1960s, the number of infants born with neural tube defects has been declining.43–45 The birth prevalence of myelomeningocele in 1970 was 1.3 per 1000 live births.43 This contrasts with a birth prevalence of 0.6 per 1000 live births after serum screening became available in the 1980s.43,2 This decrease is likely due to termination of pregnancies with a fetal neural tube defect. One should be cautious, however, not to confuse an engaged fetal head (in which the convexity may not be well visualized) for anencephaly. When we went to the fetal specialist the doctor told us spinal bifida is usually in the 7's for the AFP levels. The AFP is excreted in the fetal urine which crosses into the mother’s bloodstream. AFP is a substance made in the liver of a developing baby (fetus). Of these, babies with actual birth defects are somewhere from 1 in 16 to 1 in 33. AFP levels are normally elevated when a baby is born and then decline rapidly. If the AF-AFP is elevated (≥ 2.0 MoM), a targeted fetal sonogram (level 2) is offered. It is estimated that in every 1,000 pregnancies, 25 to 50 abnormal AFP results are obtained. Alpha-fetoprotein is produced by the fetal liver. Normal cerebral cortex is absent. Most screening programs in the United States have settled on a serum value of ≥ 2.5 MoM. The normal curvature of the spine should be documented, and the ossified posterior elements examined for abnormal splaying. The negative predictive value of a normal AF-AFP is ~97 to 99%, and elevated AF-AFP plus acetylcholinesterase allows > 99% accurate detection of NTDs.19,2 The specificity is 94.9%.20 High-resolution, targeted ultrasonography performed in conjunction with abnormal AF-AFP is also highly accurate in identifying anomalous fetuses (i.e., > 99% accurate).18,2 Tests performed on serum are further categorized by the reason for performing the test: maternal serum, adult tumor marker, and pediatric tumor marker. Surgery after birth can help rectify this. At the end of the first trimester, it is present in the fetal serum in milligram quantities, and in the amniotic fluid in microgram quantities, and in the maternal serum in quantities measured in nanograms. During a baby's development, some AFP passes through the placenta and into the mother's blood. If the preliminary, standard antepartum sonogram is unrevealing or an amniocentesis shows an elevated AF-AFP, a targeted fetal survey is performed. The ventral abdominal wall of the fetus is examined, with focused attention on the umbilical cord insertion. There has been a further decrease in birth prevalence to 0.41 per 1000 due to the Folic Acid Mandate of 1992 by the U.S. Public Health Service, which required fortification of foods with folic acid and encouraging daily folate supplements in women of child-bearing age.46, The myelomeningocele sac can be detected on sagittal or transverse views, but the sensitivity for detection of the spinal dysraphism is especially important if a sac is not seen or has ruptured. It would be ideal if a single MS-AFP level could completely segregate normal from abnormal fetuses. Your weight will be noted before the blood is drawn, since this is integral to the outcome. Your pregnancy is more advanced than thought and the due date will have to be calculated again. An AFP test screens for abnormal levels of AFP. The lab technician drawing your blood will: It is a painless process. My sister had high AFP levels when expecting my niece. normal afp levels in pregnancy A 40-year-old female asked: i spoke with a researcher at ucla in 1989 who had followed 60, 000 pregnancies, elevated afp levels, and outcomes. Eighty-nine percent of fetuses with acrania had echogenic amniotic fluid on ultrasound performed between 11 and 13 weeks.41 Owing to its irregular shape and absence of recognizable normal morphology, it is unlikely to be confused for normal brain. Thus, the choice of a judicious cutoff value that maximizes detection of anomalies and minimizes the number of false-positive results is necessary for this screening program to be effective. The fetus has a neural tube defect. Indeed, the United Kingdom has adopted this paradigm and detailed, targeted sonograms are now routinely performed as the second diagnostic step in women with high MS-AFP. The baby's intestines are outside the abdomen (belly). The following are commonly thought to be in the alpha-fetoprotein normal range. The AFP levels remained nearly at the same level as in the controls. As the baby grows and produces more AFP, the amount in the mother's blood increases.Between weeks 15 and 20 of a pregnancy, a maternal serum alpha-fetoprotein (MSAFP) screen may be offered. The intent of a standard antepartum obstetrical sonogram is to provide a general assessment of fetal/pregnancy health; it is performed according to the published guidelines endorsed by the American Institute of Ultrasound in Medicine (AIUM), ACOG, and American College of Radiology (ACR).15 The standard antepartum obstetrical sonogram is an important step in the triage of patients with high MS-AFP; impressively, approximately 20 to 50% of the elevated MS-AFP levels will be explained by findings on this preliminary sonogram (including the detection of a number of neural tube and abdominal wall defects).16,2 If the elevated MS-AFP is not explained by findings of the standard antepartum obstetrical sonogram, traditionally, the next step has been to counsel patients and offer amniocentesis for measurement of amniotic fluid (AF)-AFP. Your use of this site indicates your agreement to be bound by the Terms of Use. AFP is a protein normally made by the baby’s liver. Abnormal levels of AFP can indicate several problems. Results were fine and so was niece when born. These two groups of fetal defects (and many others) can now be accurately detected on targeted prenatal sonograms performed by experienced examiners. An AFP test helps your doctor decide if further tests or screenings are required during your pregnancy. Recall that most of the unsuspected autosomal trisomies detected with AFP screening will occur in the low MS-AFP group, and that autosomal trisomies represent the minority of abnormal karyotypes found in women with high MS-AFP. In the fetus, serum AFP level increases until ~14 to 15 weeks and then falls progressively. An AFP test is a routine screening test thats given to expectant mothers between the 14th and 22nd weeks of their pregnancy. These two groups of fetal defects (and many others) can now be accurately detected on targeted prenatal sonograms performed by experienced examiners. Although used to screen for neural tube defects, AFP is also elevated in such defects as omphalocele, gastroschisis, and sacrococcygeal teratoma, in … In most screening programs, karyotype testing is also routinely performed on the amniotic fluid specimen. Using this cutoff, ~90% of anencephalic fetuses, 75 to 80% of fetuses with an open spinal defect, 98% of fetuses with gastroschisis, and ~70% of fetuses with omphaloceles will be detected. The latter approach has become more popular in the last few years for two major reasons. If invasive procedures are recommended after the AFP test, discuss the pros and cons in detail with your doctor before taking a decision. These include mosaic trisomy 8 and trisomy 9.31,2 For example, trisomies 13, 18, and 21 account for only 28% of abnormal karyotypes in women with high MS-AFP, compared with 75% of abnormal karyotypes in women ≥ of age. AFP levels are usually high when a baby is born, but fall to very low levels by the age of 1. 2 Further, even in the absence of multiple gestations and discrete fetal defects, earlier studies suggested that women with high MS-AFP had a much higher rate of adverse pregnancy outcomes. AFP is a glycoprotein produced initially by the yolk sac and fetal gut, and later predominantly by the fetal liver. Increased Maternal Serum-Alpha-Fetoprotein: What Should You Look For? The presence of AFP greater than 500 ng/ml indicates liver cancer. Among fetal defects, the most common mechanism is through fetal cutaneous defects. In men, non-pregnant women, and children, AFP in the blood can mean that certain types of cancer—especially cancer of the testicles, ovaries, stomach, pancreas, or liver—are present.High levels of AFP may also be found in Hodgkin's disease, lymphoma, brain tumours, and renal cell cancer. Of the twin pregnancies uncomplicated by NTD 49% had AFP levels less than 2.5 MOM, 7.8% had levels greater than 5 MOM and 59% of these were associated with either abortion, stillbirth or fetus papyraceous. Indeed, the United Kingdom has adopted this paradigm and detailed, targeted sonograms are now routinely performed as the second diagnostic step in women with high MS-AFP. Since then, screening in the United States has become more widespread, and experience in this country and others has demonstrated considerable benefits from AFP screening, not only for the detection of NTDs, but also for several other fetal abnormalities (i.e., twins, ventral abdominal wall defects, and chromosomal abnormalities). The gestational age of your baby is wrong. Among fetal defects, the most common mechanism is through fetal cutaneous defects. In most screening programs, karyotype testing is also routinely performed on the amniotic fluid specimen. Some have cautioned against adopting a routine policy of circumventing the amniocentesis because (1) this approach will require a much larger number of targeted sonograms (i.e., 10 times as many), and the larger number of experienced examiners may not be available, or patients may be required to travel a long distance for the targeted sonogram; (2) even experienced examiners, especially as the prevalence of defects falls in the population scanned, may not detect as many defects as AF-AFP testing; and (3) skipping amniocentesis will cause potentially detectable chromosomal abnormalities to be missed.23,2 The last issue remains controversial, and multicenter consensus has not been reached. It is a protein made in the liver of a developing baby. Current guidelines recommend targeted screening of women at high risk, including those with a history of thyroid disease, type 1 diabetes mellitus, or other autoimmune disease; current or past use of thyroid therapy; or a family history of autoi… An AFP test measures the level of AFP in pregnant women during the second trimester of pregnancy. Accurate sonographic diagnosis has become extremely important in light of AFP screening in pregnancy. Usually, you have a very small amount of alpha-fetoprotein (AFP) in your body. 8 Signs of a Multiple or Twin Pregnancy. A normal AFP result cannot be taken as a guarantee that your pregnancy will be a normal one, or the baby born healthy. Maternal Serum Screening Test Positive for Down Syndrome, ULTRASOUND EVALUATION OF MULTIPLE PREGNANCIES, THE PRENATAL MANAGEMENT OF THE FETUS WITH A CORRECTABLE DEFECT, Ultrasonography in Obstetrics and Gynecology. While the exact function of AFP is unknown, it is made by the fetal liver, and the level of AFP rises and falls at specific times in the pregnancy. These included 710 NTDs (417 anencephaly, 247 spina bifida, and 46 encephalocele), 286 ventral abdominal wall defects, 163 fetuses with Down syndrome, and 231 cases of other chromosomal anomalies. Additional testing can give you a confirmed diagnosis, following which you can find out if any medical interventions are possible, or start making lifestyle changes that might be necessary when bringing up a child with special needs. Decisions to perform an amniocentesis versus a targeted sonogram will vary according to patient (maternal age, other serologic markers, e.g., HCG and estriol, and personal choice) and institution (depending on availability of experienced sonologists). Expected rates of sonographic detection for neural tube and abdominal wall defects are currently > 90%.21–27 It is estimated that a complete, detailed, normal sonogram can now reduce the MSAFP-based risk of a neural tube or ventral abdominal wall defect by 95%.28,2 Second, going directly to a targeted sono-gram circumvents the small, but important procedural risk of fetal loss from amniocentesis. Soreness or pain at the spot where the needle was inserted. A focused examination of the neural axis in each fetus should include an assessment of overall cranial size and contour, ventricular size (transaxial diameter of ventricular atrium > 10 mm is abnormal), and posterior fossa, including cerebellar morphology and cisterna magna.36–39 At the University of California–San Francisco, we also include images of the cavum septum pellucidum as a check for forebrain malformations. The examiner should maintain a heightened sensitivity to the presence of bowel loops within the umbilical cord or floating in the amniotic fluid distant from the cord insertion/abdominal wall. This can happen when the due date has been miscalculated and you are earlier in your pregnancy than the initial estimate. In the fetus, serum AFP level increases until ~14 to 15 weeks and then falls progressively. Further, fetuses with autosomal trisomies 13, 18, 21 detected as a result of high MS-AFP often have sonographically detectable structural abnormalities.25,2 If the targeted sonographic fetal survey in a woman with elevated MS-AFP is normal, it has been estimated that the risk of a fetal chromosomal abnormality is only 0.6 to 1.1%, and sex chromosome aberrations (other than 45X) account for many (30 to 50%) of the chromosomal abnormalities in these fetuses.24–28, There is no right or wrong choice, all women facing the choice of targeted sonography versus amniocentesis should be fully informed of these controversies during their counseling. It is found in the fluid surrounding the baby in the womb (amniotic fluid). Your pregnancy is more advanced than thought and the. On average, anencephaly is associated with the highest AF-AFP and MS-AFP values of all NTDs, and ~90% will be detected by an MS-AFP ≥ 2.5 MoM. This is a simple blood test done on an outpatient basis, usually at a diagnostic lab. Twins - Ways to Confirm. However, the most common reason for elevated AFP levels is inaccurate dating of the pregnancy. She was tested again a couple of weeks later and it was higher. A focused examination of the neural axis in each fetus should include an assessment of overall cranial size and contour, ventricular size (transaxial diameter of ventricular atrium > 10 mm is abnormal), and posterior fossa, including cerebellar morphology and cisterna magna.36–39 At the University of California–San Francisco, we also include images of the cavum septum pellucidum as a check for forebrain malformations. These fetal deaths occur mainly in the second trimester, and the risk appears to be directly related to the degree of MS-AFP elevation.4. Researchers opine that lower the MoM value of PAPP-A, higher are the risks of poor pregnancy results. Among the first 1.1 million women screened through the California AFP Screening Program, 1390 fetal anomalies (morphological and chromosomal) were detected (prevalence of 1.3/1000). If your AFP results show abnormal levels, discuss this with your doctor, or you may be referred to a genetic counsellor. The level of alpha feto-protein starts to decrease soon after birth and is very low in normal adults i.e., less than 10 ng/ml (nanogram per milliliter). Unfortunately, this is impossible owing to considerable overlap in MS-AFP levels between normal and abnormal pregnancies. Currently, over 300,000 pregnant women in California are tested annually. Several other important fetal anomalies are associated with elevated AFP, and these potential defects should also be sought on the targeted sonogram (Table 17–1).
