Maternal Serum Screening: How It Can Detect Genetic Disorders in the Baby
Maternal serum screening test provides insights into the first and second trimesters, detecting potential genetic abnormalities and ensuring
Maternal Serum Screening (MSS) is a vital part of prenatal care, offering expectant mothers a non-invasive way to assess the risk of genetic disorders, birth defects, and pregnancy complications. At MedGenome Labs, we provide advanced MSS solutions that deliver clarity, reassurance, and actionable insights—helping families make informed decisions during pregnancy.
🧬 What Is Maternal Serum Screening?
Maternal Serum Screening is a set of blood tests performed during pregnancy to evaluate the likelihood of fetal chromosomal abnormalities and neural tube defects. It is typically conducted in two phases:
First Trimester (9–13 weeks 6 days): The Double Marker Test measures levels of Free Beta hCG and PAPP-A to assess the risk of Down syndrome and other anomalies.
Second Trimester (15–21 weeks 6 days): The Quadruple Marker Test evaluates four substances in maternal blood:
Alpha-fetoprotein (AFP)
Human chorionic gonadotropin (hCG)
Unconjugated estriol (uE3)
Inhibin A
These markers help detect conditions such as:
Trisomy 21 (Down syndrome)
Trisomy 18 (Edwards syndrome)
Neural tube defects like spina bifida
Risk of pre-eclampsia and other complications
✅ Why Is Maternal Serum Screening Important?
MSS offers several key benefits:
Non-invasive and safe: Requires only a blood sample from the mother.
Early risk assessment: Helps identify high-risk pregnancies.
Supports informed decision-making: Enables timely follow-up with diagnostic tests like NIPT or amniocentesis.
Accessible and cost-effective: Widely available across India.
While MSS is a screening—not diagnostic—test, it plays a critical role in guiding further evaluation and care.
