54+ booked in last 3 daysOverview
The Pregascreen Dual Test (also called First Trimester Serum Dual Marker Test) is a prenatal screening test done in the first trimester (between 8 and 13.6 weeks of pregnancy) to assess the chance of fetal chromosomal abnormalities like Down syndrome (Trisomy 21), neural tube defects, Trisomy 18 etc. It measures two substances in the mother's blood viz. Pregnancy-associated plasma protein-A (PAPP-A) and Free beta-human chorionic gonadotropin (free ß-hCG) and provides a risk assessment. If the initial screening shows a higher-than-average risk, a confirmatory test like Non-Invasive Prenatal Testing (NIPT) or Karyotyping/FISH of chorionic villus sampling (CVS) is recommended for a more precise diagnosis.
