Both JScreen and 23andMe offer carrier screening – tests to identify parents who are at risk to have a child with a genetic condition – but the screening differs in several ways (see table below).
JScreen’s carrier screening is more comprehensive and includes genetic counseling, so patients can understand their results. Carrier screening offered by 23andMe is less extensive, so it may miss important genetic information. It is also combined with non-medical screening for personal health and other traits.
