PAPP-A

The PAPP-A Test is an important component of first trimester prenatal screening. Pregnancy Associated Plasma Protein-A is produced by the placenta and normally increases as pregnancy progresses. Measuring its concentration provides valuable information about placental function and fetal development. Low PAPP-A levels may be associated with an increased risk of chromosomal abnormalities, pregnancy complications, restricted fetal growth, pre-eclampsia, preterm birth and stillbirth. The PAPP-A Test is performed alongside maternal age ultrasound findings and other blood test results to calculate an overall risk estimate. Because it is a simple blood test and carries no risk to developing babies, it has become a routine part of prenatal care in many healthcare settings. Early identification of pregnancies at increased risk allows healthcare professionals to offer additional investigations, closer monitoring and appropriate medical management throughout pregnancy.

What is the PAPP-A Test?

The PAPP-A (Pregnancy-Associated Plasma Protein-A) Test is a laboratory blood test used to measure the level of Pregnancy Associated Plasma Protein-A in a mother's blood. PAPP-A is a protein produced mainly by the placenta during pregnancy and plays an important role in growth and the development of the fetus. The test is most performed during the first trimester of pregnancy between the 11 and 13 weeks plus 6 days as part of the prenatal screening for chromosomal abnormalities. The PAPP-A Test is combined with free Beta hCG blood test and nuchal translucency NT ultrasound to assess the risk of conditions such as Down syndrome Trisomy 21 Edwards syndrome Trisomy 18 and Patau syndrome Trisomy 13. It is a screening test rather than a diagnostic test meaning that it estimates the likelihood of these conditions but does not confirm their presence.

What are the Benefits of PAPP-A Test?

• Safe and minimally invasive
• Requires only a simple blood sample
• No risk to the fetus
• It supports early prenatal screening
• It helps identify high-risk pregnancies
• It assists healthcare professionals in pregnancy management
• It improves early detection of chromosomal abnormalities
• It can be combined with ultrasound for greater accuracy
• Supports informed clinical decision-making
• Helps determine the need for additional diagnostic tests

What are the Limitations of the PAPP-A Test?

• It is a screening test and not a diagnostic test
• Cannot confirm fetal abnormalities
• Abnormal results require additional testing
• Results depend on accurate pregnancy dating
• Maternal factors can influence results
• Laboratory values may vary slightly
• False-positive and false-negative results may occur
• Cannot identify all genetic disorders
• Additional ultrasound examinations may be required
• Professional interpretation is essential

What is the Procedure of the PAPP-A Test?

• Verification of the patient's identity
• Review of pregnancy history and clinical information
• Confirmation of gestational age
• Explanation of the test procedure
• Selection of a suitable vein for blood collection
• Clean the skin with an antiseptic solution
• Insertion of a sterile needle into the vein
