Book a Test- Double Marker (Pregnancy)

The Double Marker test is a prenatal screening test used to detect potential chromosomal abnormalities in a developing fetus. The test is typically performed between 11 and 14 weeks of pregnancy and measures the levels of two specific substances in the mother's blood: free beta-human chorionic gonadotropin (free beta-hCG) and pregnancy-associated plasma protein-A (PAPP-A). Abnormal levels of these substances can indicate an increased risk of chromosomal abnormalities, such as Down syndrome (trisomy 21) or trisomy 18. The Double Marker test is often used in conjunction with ultrasound imaging to provide a more comprehensive assessment of fetal health. While the test can provide valuable insights, it is essential to note that it is not a diagnostic test, but rather a screening tool that can help identify potential risks. A positive result typically requires follow-up testing, such as amniocentesis or chorionic villus sampling.
