PAPP - A
The PAPP-A test measures Pregnancy-Associated Plasma Protein A levels in the blood and is used in early pregnancy screening to assess the risk of chromosomal abnormalities.
The PAPP-A (Pregnancy-Associated Plasma Protein A) test is a blood test commonly performed during the first trimester of pregnancy. It measures the level of PAPP-A, a protein produced by the placenta, which plays an important role in fetal growth and development.
This test is typically included as part of first-trimester screening, along with other markers and ultrasound findings, to assess the risk of chromosomal abnormalities such as Down syndrome (Trisomy 21) and other genetic conditions.
Abnormal levels of PAPP-A may also be associated with pregnancy complications such as preeclampsia, preterm birth, or restricted fetal growth. Early detection helps in closer monitoring and better management of pregnancy.
The purpose of this test is to
- To measure PAPP-A levels in the blood
- To assess the risk of chromosomal abnormalities
- To support first-trimester prenatal screening
- To evaluate placental function
- To help identify risk of pregnancy-related complications
