Triple Screen Test in Chennai

Know More About This Test

The Triple Marker Test is a prenatal screening test performed during the second trimester of pregnancy. It measures three substances in maternal blood—AFP, hCG, and unconjugated estriol—to assess the risk of chromosomal abnormalities and neural tube defects in the fetus.

This test estimates risk rather than providing a definitive diagnosis.

Why Is This Test Recommended?

What Do the Results Indicate?

Abnormal marker levels may indicate increased risk of Down syndrome, Edwards syndrome, or neural tube defects.

How Is the Test Performed and Prepared For?

A blood sample is collected. No fasting is required.
