86% of affected
pregnancies no longer missed

86% of affected pregnancies detected by expanded carrier screening (ECS) are missed when screening for cystic fibrosis and spinal muscular atrophy alone.1

Learn how ECS detects more at-risk couples for serious conditions >

76% of couples
took action

76% of couples found by ECS to be at risk for severe or profound conditions pursued alternative reproductive actions such as prenatal diagnosis or IVF with preimplantation genetic diagnosis.2

100X fewer
false positives

The false positive rate of non-invasive prenatal screening (NIPS) is 100x lower than serum screening in patients <35 years old.3

Learn why NIPS leads to fewer unnecessary invasive procedures >

50% of hereditary cancers are non BRCA1/2

At least 50% of hereditary cancers are caused by genes other than BRCA1 and BRCA2.4
