Triple test

From WikiMD's Wellnesspedia

Triple test is a prenatal screening procedure used to determine if a pregnancy could be at risk for certain birth defects. This test, also known as the multiple marker screening or AFP Plus, measures the levels of three specific substances in a pregnant woman's blood: Alpha-fetoprotein (AFP), Human chorionic gonadotropin (hCG), and Estriol.

Procedure[edit | edit source]

The Triple test is typically performed between the 15th and 20th weeks of pregnancy. It involves taking a blood sample from the pregnant woman, which is then sent to a laboratory for analysis. The levels of AFP, hCG, and Estriol in the blood are measured and compared to average levels for women at the same stage of pregnancy.

Interpretation[edit | edit source]

The results of the Triple test are used to calculate a risk score for certain birth defects, including Down syndrome, Trisomy 18, and neural tube defects. It's important to note that the Triple test is a screening test, not a diagnostic test. This means it can only indicate a higher risk of these conditions, not confirm them. If the test results indicate a higher risk, further diagnostic tests such as amniocentesis or chorionic villus sampling may be recommended.

Risks and Limitations[edit | edit source]

The Triple test is a non-invasive procedure with no physical risks to the mother or baby. However, it does have limitations. The test can produce false-positive results, indicating a problem when the baby is actually healthy. It can also produce false-negative results, failing to detect a problem that is present. Furthermore, the test does not screen for all birth defects, only the ones mentioned above.
