Pregnancy is an exciting yet delicate phase, and for many expecting parents, ensuring their baby’s health and wellbeing is a top priority. Advances in medical technology have made it possible to identify potential risks early, offering clarity and peace of mind. One such critical prenatal screening is the Double Marker Test, a blood test that helps detect chromosomal abnormalities in the baby.
This test is part of routine prenatal care and provides vital information about potential genetic conditions like Down syndrome, helping parents make informed decisions. For accurate prenatal screening, Mamata Fertility Hospital Hyderabad, a trusted name in pregnancy and childbirth care, offers the expertise you need for a safe and healthy pregnancy.
Purpose of the Double Marker Test
The Double Marker Test is primarily used to assess the risk of chromosomal abnormalities in the developing baby. It is typically combined with other screening methods like the NT (Nuchal Translucency) scan for a more comprehensive analysis.
What does it detect?
This screening detects abnormalities in chromosomes, which are the genetic building blocks of a baby’s development. The conditions it focuses on include:
- Down syndrome (Trisomy 21): A genetic condition that can lead to developmental delays and intellectual disabilities.
- Trisomy 18: A severe chromosomal disorder that affects the baby’s physical and mental growth.
- Trisomy 13: A rare condition associated with severe neurological and physical abnormalities.
By identifying the likelihood of these conditions early, the test empowers parents and doctors to take necessary steps for further evaluation or preparation.
Procedure of the Double Marker Test
The Double Marker Test is a non-invasive screening that involves a simple blood test. It’s typically recommended for women in their first trimester, between 9 to 13 weeks of pregnancy.
How is it conducted?
- Blood Sample Collection
A blood sample is drawn from the expectant mother, usually during a regular prenatal visit to the healthcare provider.
- Laboratory Analysis
- The blood sample is analyzed to measure two specific markers:
- Free beta-human chorionic gonadotropin (β-hCG): A hormone produced by the placenta.
- Pregnancy-associated plasma protein-A (PAPP-A): A protein linked to the development of the placenta.
- Abnormal levels of these markers may indicate an increased risk of chromosomal abnormalities.
- Risk Assessment
The results are combined with other factors, such as the mother’s age, gestation length, and findings from an NT scan, to estimate the baby’s risk of chromosomal abnormalities.
This quick and straightforward test is painless and poses no risk to you or your baby, making it a highly preferred choice among expectant mothers in the early stages of pregnancy.
Accuracy and Benefits of the Double Marker Test
While the Double Marker Test is not a diagnostic tool, it provides a reliable screening for chromosomal abnormalities, prompting necessary follow-ups if the risk is deemed high.
Accuracy
- The test boasts high sensitivity when combined with an NT scan, offering accurate risk calculations.
- It’s essential to note that this test is a screening tool and not a definitive diagnosis.
Key Benefits
- Early Detection: The test helps identify potential chromosomal abnormalities early in the pregnancy.
- Peace of Mind: It reassures parents if the results indicate low risk.
- Guided Decisions: Results from the test guide doctors in recommending additional diagnostic tests like amniocentesis or CVS if needed.

Who Should Consider the Double Marker Test?
While the Double Marker Test is commonly recommended for most pregnancies, certain groups may particularly benefit from it:
- Women over 35 years of age
Advanced maternal age increases the risk of chromosomal abnormalities.
- History of Genetic Conditions:
Families with a history of genetic disorders or previous pregnancies with abnormalities.
- High-Risk Pregnancies:
Those with underlying medical conditions or other risk factors identified during antenatal care.
If you fall into any of these categories, consulting experts at Mamata Fertility Hospital Hyderabad will ensure personalized care and guidance throughout your pregnancy.
