Pregnancy is a journey filled with excitement, joy, and a deep sense of responsibility. Among the many steps taken to ensure a healthy pregnancy, prenatal screenings play a critical role. One such essential test during the first trimester is the Double Marker Test. This test provides valuable insight into the baby’s genetic health and helps detect potential chromosomal abnormalities early on.
At SRISHTI FERTILITY AND IVF CENTRE, we emphasize comprehensive prenatal care, and the Double Marker Test is one of the cornerstones of our first-trimester screening protocol. Let’s dive into why this test is so crucial, what it involves, and how it benefits expecting parents.
What is the Double Marker Test in Pregnancy?
The Double Marker Test in pregnancy is a specialized blood test used to assess the risk of chromosomal abnormalities in the developing fetus. It evaluates two key biochemical markers in the mother’s blood:
- Free Beta-Human Chorionic Gonadotropin (Free β-hCG) – A hormone produced by the placenta that helps maintain pregnancy. Abnormal levels can indicate chromosomal issues like Down syndrome.
- Pregnancy-Associated Plasma Protein-A (PAPP-A) – A protein that supports fetal growth. Low levels are often associated with an increased risk of certain chromosomal conditions.
This test is typically conducted between the 9th and 13th weeks of gestation and is often combined with the Nuchal Translucency (NT) scan to provide a more comprehensive risk assessment.
Key Features:
- Non-invasive and safe
- Simple blood test
- No dietary or fasting requirements
- Provides risk probability, not a diagnosis
Why Is the Double Marker Test Important?
Early detection of genetic abnormalities allows parents to prepare emotionally, mentally, and medically. Here are the primary reasons this test is crucial:
1. Detects Common Chromosomal Disorders
It helps in identifying the risk of:
- Down Syndrome (Trisomy 21): A genetic condition causing developmental delays and intellectual disability.
- Trisomy 18 and Trisomy 13: Rare but severe genetic conditions associated with significant health complications.
2. Supports Early Decision-Making
The earlier potential risks are identified, the more time parents and doctors have to make informed decisions, whether it’s further testing or planning for specialized care.
3. Peace of Mind for Expecting Parents
Receiving low-risk results can significantly reduce anxiety during pregnancy.
4. Guides Further Testing
If the test indicates a high risk, your doctor may recommend additional, more definitive tests like:
- Non-Invasive Prenatal Testing (NIPT)
- Chorionic Villus Sampling (CVS)
- Amniocentesis
Understanding Double Marker Test in Pregnancy Normal Values
The test results are interpreted in terms of risk levels:
- Low Risk: Indicates that the chance of the baby having a chromosomal abnormality is minimal.
- High Risk: Suggests a higher probability and often warrants further diagnostic testing.
General Reference Ranges:
(Note: These may vary slightly by laboratory and gestational age)
- Free β-hCG: 25,700 to 288,000 mIU/ml
- PAPP-A: 0.5 to 2.5 MoM (Multiples of the Median)
The interpretation of these values depends on multiple factors including:
- Maternal age
- Gestational age
- NT scan results
- Ethnicity and weight of the mother
Always consult with a qualified medical professional for accurate interpretation.
Who Should Take the Double Marker Test?
While the test is beneficial for all pregnant women, it is particularly recommended for:
- Women aged 35 or older
- Those with a family history of genetic disorders
- Women with abnormal NT scan results
- IVF-conceived pregnancies
- Expecting mothers with pre-existing medical conditions
Taking this test is a proactive way to safeguard the health of both the baby and the mother.
What to Expect During the Test
The Double Marker Test is straightforward and non-invasive. Here’s what typically happens:
- A small blood sample is drawn from the mother’s arm.
- No special preparation like fasting is needed.
- The test takes only a few minutes.
- Results are usually available within 3 to 5 working days.
Based on your results, your doctor will guide you on the next steps, if any.

FAQs About the Double Marker Test
Is the test compulsory?
No, but it is highly recommended for early detection of chromosomal abnormalities.
Is it safe?
Yes, it’s a simple blood test with no risk to the mother or baby.
What happens if the result is high risk?
Your doctor may suggest follow-up tests like NIPT, CVS, or amniocentesis for confirmation.
Can the test confirm any condition?
No. It only indicates risk levels. A positive result does not mean the baby has a disorder, but that further testing is advised.
