Carrier Screen

Carrier screening is a type of genetic testing performed on people who display no symptoms for a genetic disorder, but may be at risk for passing it on to their children. A carrier for a genetic disorder has inherited one normal and one abnormal copy of a gene associated with the disorder. Carrier screening is often performed prior to becoming pregnant or during pregnancy to allow for informed decision making. These tests most often help identify carriers of disorders that are childhood onset with severe symptoms, such as immunodeficiencies and several metabolic diseases.

A comprehensive menu of carrier screen tests are available through the Northwell Health Genetics Alliance. Commonly ordered tests are listed below.
