Double Marker Test

Description

About Double Marker Test in Delhi

The Double Marker Test is a prenatal screening test done in the first trimester of ... pregnancy. It measures specific hormones in the mother’s blood to detect the risk of chromosomal abnormalities such as Down syndrome, Trisomy 18, and Trisomy 21. Many reputed diagnostic centers in Delhi offer this test with accurate results and timely reports.

Preparations Before a Double Marker Test

There is no special preparation needed for this blood test. However, doctors usually combine it with an NT (Nuchal Translucency) scan, so fasting may be advised depending on the clinic’s protocol. It’s important to carry previous medical reports and ultrasound results to the test center.

What To Expect During the Procedure

The Double Marker Test is a simple blood draw from the pregnant woman’s arm. The procedure takes just a few minutes and is generally painless and safe. The sample is sent to a lab for analysis, and the report is typically ready within 2–5 days, depending on the lab.

Why Doctors Recommend Double Marker Test

Doctors recommend this test to assess the baby’s risk of developing certain genetic conditions early in pregnancy. It helps expecting parents make informed decisions about further diagnostic procedures like amniocentesis or CVS, especially in high-risk pregnancies or women above age 35.

Types of Birth Defects Identified by a Double Marker Test

The Double Marker Test is used to screen for:

Down syndrome (Trisomy 21)

Edwards syndrome (Trisomy 18)

Patau syndrome (Trisomy 13)
These are chromosomal abnormalities that can cause developmental delays and physical defects.

Understanding the Test Results

The test gives a risk score rather than a yes-or-no answer. Results are classified as low risk or high risk. A high-risk result doesn’t mean the baby definitely has a condition—it indicates that further tests (like NIPT or amniocentesis) may be needed to confirm.

Tips to Reduce the Risk of Birth Defects

Take prenatal vitamins with folic acid

Avoid alcohol, smoking, and harmful drugs

Maintain a healthy diet and stay active

Attend all prenatal checkups and screenings

Manage chronic conditions like diabetes or thyroid problems
These steps can help ensure a healthy pregnancy and reduce the risk of complications.
