2022年8月23日 · What is an AFP (alpha-fetoprotein) tumor marker test? An AFP tumor marker test is a blood test that measures the level of AFP (alpha-fetoprotein) in a sample of your blood. It's usually used to help diagnose certain types of cancer and …

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. What is an alpha-fetoprotein test?

2024年2月21日 · Usually, you have a very small amount of alpha-fetoprotein (AFP) in your body. But when you have liver disease, some types of cancer, or are pregnant, you'll usually have more of it in your...

2023年6月7日 · Alpha-fetoprotein (AFP) is a tumor marker used to detect and diagnose certain cancers and liver diseases. AFP blood testing may also be performed during pregnancy to determine a baby's risk for a congenital disability or genetic disorder.

2024年5月1日 · There are 2 types of immunoassays for measuring AFP: (1) competitive and (2) two-site solid-phase immunometric assays. In a typical radioisotopic competitive type, purified iodine-125-labeled AFP is mixed with the sample containing AFP to compete for a limited amount of AFP antibody.

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. High levels of AFP may suggest the developing baby has a neural tube defect such as spina bifida or anencephaly.

2017年6月7日 · An alpha-fetoprotein (AFP) test is a blood test that measures the amount of AFP present in blood. It’s usually part of what’s called a triple screen or quad screen...

2019年6月1日 · Individuals at risk for HCC are typically monitored with serial hepatobiliary ultrasound (US), other imaging techniques (eg, CT scans), and serial measurements of alpha-fetoprotein (AFP)—a glycoprotein synthesized by the fetal yolk sac, fetal liver, testicular non-seminomatous germ cell cancers, and malignant hepatic cells.

The AFP test is highly versatile and widely used in both prenatal care and adult diagnostics. For pregnant women, it is often included in the maternal serum alpha-fetoprotein (MSAFP) screening test, which helps identify risks for birth defects like spina bifida or Down syndrome. For adults, the AFP tumor marker test provides critical insights ...

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. AFP is a protein mostly made in ...
