Alpha-fetoprotein (AFP) tests are blood tests all pregnant women should get. They measure levels of AFP, a protein that develops in the fetus’s liver. Irregular AFP levels can point to problems such as genetic disorders or neural tube defects. If you have an atypical AFP test result, you'll need follow-up testing.

The AFP test is measuring high and low levels of alpha-fetoprotein. The results are combined with the mother’s age and ethnicity in order to assess the probabilities of potential genetic disorders.

AFP is a major plasma protein produced by the yolk sac and the fetal liver during fetal development. It is thought to be the fetal analog of serum albumin. AFP binds to copper, nickel, fatty acids and bilirubin [8] and is found in monomeric, dimeric and trimeric forms. AFP is a glycoprotein of 591 amino acids [11] and a carbohydrate moiety. [12]

2024年2月11日 · Unborn babies normally make alpha-fetoprotein (AFP), and it shows up in their mother's blood. Checking the level of AFP in a mom-to-be can show if their baby may have problems with their neural...

This article is an overview of fetal diseases, birth defects, and genetic syndromes that can be diagnosed in utero thanks to elevated levels of AFP in maternal serum during the additional use of AFP in prenatal screening, especially in the second and third trimesters (Figure 1) [1, 3].

An AFP test is a blood test that measures the level of alpha-fetoprotein (AFP) in your blood when you are pregnant. The test checks your baby's risk of having certain birth defects and genetic problems, but it does not diagnose any health conditions. The test is usually done between 15 and 20 weeks of pregnancy.

Learn about the Maternal Serum Alpha-Fetoprotein (AFP) test, a key prenatal screening tool for detecting birth defects like neural tube defects and Down syndrome. Understand AFP levels, test procedures, and what abnormal results mean for your pregnancy.

The fetal liver produces α1-globulin called alpha-fetoprotein (AFP). AFP will become the dominant fetal protein in the first trimester, reaching its peak at 12 weeks gestation.

2023年7月19日 · AFP (alpha-fetoprotein) testing is a blood test done during pregnancy to assess the fetus's risk of birth defects or genetic abnormalities. Outside of pregnancy, an AFP test will evaluate and monitor certain cancers—like liver cancer and ovarian or testicular tumors.

What is an alpha-fetoprotein screening (AFP)? Alpha-fetoprotein screening is a blood test that measures the level of alpha-fetoprotein in the mothers' blood during pregnancy. AFP is a protein normally produced by the fetal liver and is present in the fluid surrounding the fetus (amniotic fluid), and crosses the placenta into the mother's blood.
