Summary

This study tested a cell-free DNA blood test to screen for trisomy 21, 18, 13 and 22q11.2 deletion in over 1,100 pregnant women during the first trimester. The goal was to see how accurate the test is compared to standard combined screening. Researchers measured how often the test gave a positive result, a false positive, or no result at all.
