Sema4 Expanded Carrier Screening

Sema4 has launched a larger Expanded Carrier Screen for family planning with personalized residual risk.

The test analyzes 502 genes associated with clinically relevant conditions, up from 283 genes, to cover more rare diseases. The test detects more high-risk pregnancies and identifies up to 30 times more carrier couples, Sema4 CEO Eric Schadt said in a statement. It also incorporates low-pass genome analysis to detect ancestry markers that to refine the accuracy of results.
