Triple Marker Test vs Quadruple Marker Test: Differences & Accuracy in Pregnancy

For expectant mothers, prenatal screenings are a normal part of tracking your baby's development. During the second trimester, doctors recommend blood tests to assess the risk of chromosomal conditions. When choosing your screening options, understanding the differences between the triple vs quadruple marker test is essential to getting the most accurate information.

This comprehensive guide details the hormones measured by both tests, compares their accuracy rates, and explains how to interpret your results.

Screening Differences and Accuracy

Triple screen measures AFP, hCG, and Estriol. Quad screen adds Inhibin-A, boosting detection accuracy to 85%. False-positive rates are lower in the Quad test. Read about hormone roles in our Beta hCG test guide. A positive screen requires confirmation scans or amniocentesis.
