What is the Double Marker Test?
The Double Marker Test , also known as the Maternal Serum Screening Test , is a blood test performed during the 11th to 14th week of pregnancy . It measures primarily two substances in the mother's blood:
Free Beta-hCG (Human Chorionic Gonadotropin): A hormone produced during pregnancy.
PAPP-A (Pregnancy-Associated Plasma Protein A): A protein released by the placenta.
Abnormal levels of these markers may indicate a higher risk of chromosomal abnormalities in the fetus such as:
Down Syndrome (Trisomy 21)
Edwards Syndrome (Trisomy 18)
Patau Syndrome (Trisomy 13)
Why is the Double Marker Test Important?
Detects genetic abnormalities in the early stage of pregnancy.
Helps doctors categorize pregnancies into low-risk or high-risk groups.
Provides parents with clarity and the option of further diagnostic tests if required.
Completely safe and non-invasive for both mother and baby.
Useful for managing high-risk pregnancies.
Who Should Take the Double Marker Test?
While it is recommended for all pregnant women, it is particularly important for:
Women aged 35 years or older .
Couples with a family history of genetic disorders .
Women who have had previous abnormal pregnancies .
Patients who conceived through IVF or assisted reproductive techniques .
Test procedure
A blood sample is collected from the mother.
The levels of Free Beta-hCG and PAPP-A are measured.
The results are often combined with an Ultrasound Nuchal Translucency (NT) Scan for higher accuracy.
Based on the findings, doctors may suggest further diagnostic tests like Amniocentesis or Chorionic Villus Sampling (CVS) if the pregnancy is marked as high risk.
Normal Range & Interpretation
High Free Beta-hCG with Low PAPP-A: May indicate Down Syndrome.
Low Beta-hCG and Low PAPP-A: May suggest Edwards Syndrome or Patau Syndrome.
It is important to note that the Double Marker Test is a screening test, not a diagnostic test . Only a gynecologist can interpret the results in combination with other clinical factors.
