A blood test can check for rising levels of alpha fetoprotein, indicative of fetal problems.

Alpha fetoprotein: A substance produced by the fetus.

Serum alpha fetoprotein is not elevated in classical seminoma.

To test for the birth defects, technicians first look for the fetal protein, alpha fetoprotein, in the pregnant woman's blood.

Certain body chemicals such as alpha fetoprotein and beta human chorionic gonadotrophin are produced by some testicular cancers.

The benefits of serum alpha fetoprotein and abdominal sonography as screening tools for HCC have not been studied in children.

Such tumor markers are, for instance, CEA (carcinoembryonic antigen) and AFP (alpha fetoprotein).

In the fourth phase of progress, population-based antenatal screening - maternal serum alpha fetoprotein and ultrasound screening, sometimes complemented by amniocentesis - has been proven to have a substantial effect.

As they report in the current issue of The Lancet, a British medical journal, alpha fetoprotein and estriol levels are low in the first trimester in blood of women carrying fetuses with Down's syndrome.

Some clinicians recommend monitoring HBV-infected children or adolescents for HCC with baseline screening and then yearly determinations of serum alpha fetoprotein levels and abdominal ultrasonography; however, no data support the benefit of such surveillance (641,657,659,660).

Some experts will perform periodic sonographic screening at defined intervals (every 2--5 years) in children with chronic HCV infection; others will do these tests only in those with advanced liver disease and/or rising serum alpha fetoprotein concentrations (748).

Other tests may include liver function tests (LFT), CT scan, MRI, ultrasound, biphasic helical CAT scan, alpha fetoprotein, PIVKA-II, glucose, hepatitis screening, and ECG.

Second trimester maternal serum screening (AFP screening, triple screen, quad screen, or penta screen) can check levels of alpha fetoprotein, β-hCG, inhibin-A, estriol, and h-hCG (hyperglycosolated hCG) in the woman's serum.

The researchers have discovered, by chance more than by design, that at about 16 to 18 weeks into gestation fetuses with Down's syndrome are making abnormally small amounts of two fetal proteins, estriol and alpha fetoprotein, and abnormally large amounts of another, human chorionic gonadotropin.

Same Blood Sample Used Doctors already routinely obtain blood samples from women at the 16th week of pregnancy to test for alpha fetoprotein levels as a screening test for neural tube defects, developmental defects that can often lead to partial paralysis and sometimes to mental retardation.

Women with high levels of the protein in their blood are referred for sonograms and those with suspicious sonograms are referred for amniocentesis, in which doctors examine the amniotic fluid that surrounds the fetus and confirm the high levels of alpha fetoprotein.

Although no evidence-based long-term monitoring guidelines exist for children with perinatally acquired HCV, many experts monitor HCV RNA levels and serum transaminase levels every 6--12 months and hemogram and serum alpha fetoprotein levels annually (748).

First trimester maternal serum screening can check levels of free β-hCG, PAPP-A, alpha fetoprotein, intact or beta hCG, inhibin-A, or h-hCG in the woman's serum, and combine these with the measurement of nuchal translucency (NT).

But 10 percent of those tested are found to have too much alpha-fetoprotein in their blood.

The test is for alpha-fetoprotein in the mother's blood.

Levels of certain substances in the fluid sample, such as alpha-fetoprotein, can also be checked.

The most common method of testing for hepatoblastoma is to a blood test checking the Alpha-fetoprotein.

Alpha-fetoprotein a molecule produced in the developing embryo and fetus.

The level of alpha-fetoprotein in the blood.

'And he did do the alpha-fetoprotein screening this week?'

Elevation of alpha-fetoprotein has been seen in pancreatoblastoma.

Amniocentesis (to look for increased levels of alpha-fetoprotein)

In some cases the second trimester can see elevated maternal serum alpha-fetoprotein levels, though this is also an indicator of many other conditions.

Alpha-fetoprotein, the predominant serum protein of the fetus which gives way to albumin in the adult.

"Your alpha-fetoprotein is slightly elevated.

In the 1970s, he showed that fetal neural tube defects could be detected by measuring alpha-fetoprotein in the mother's blood.

Elevated alpha-fetoprotein refers to a state where Alpha-fetoprotein levels are outside of the reference range.

The only prenatal screen routinely recommended for every pregnancy is an alpha-fetoprotein, or AFP, level.

Alpha-Fetoprotein in Blood.

Increased serum levels of alpha-fetoprotein are sometimes found in Citrullinemia and Argininosuccinate synthetase deficiency.

This is because, DES is an artificial estrogen that alpha-fetoprotein does not bind to.

The disorder can be screened for during pregnancy by finding elevated levels of alpha-fetoprotein on a routine sampling of amniotic fluid.

At my routine November exam, Dr. Shapiro informed me that my alpha-fetoprotein was rising again.

The MSAFP test measures the level of alpha-fetoprotein, a protein produced by the fetus.

Vitamin D-binding protein belongs to the albumin gene family, together with human serum albumin and alpha-fetoprotein.

Combined with alpha-fetoprotein, β-HCG is an excellent tumor marker for the monitoring of germ cell tumors.

Non-invasive techniques include examinations of the woman's womb through ultrasonography and maternal serum screens (i.e. Alpha-fetoprotein).

A number of blood transport proteins are evolutionarily related, including serum albumin, alpha-fetoprotein, vitamin D-binding protein and afamin.
