The JScreen Jewish genetic test is best utilized before a person or couple is planning to become pregnant for the first time, or planning to expand their families, so that they can understand their risks and options. This simple, saliva-based assay (spit test) is done in the privacy and convenience of your home and is then mailed to a CLIA-certified laboratory. JScreen analyzes genetic markers for more than 200 different diseases, including those that are predominant in the Jewish community. Cutting-edge genetic testing can be very expensive; the JScreen initiative ensures that for individuals with private health insurance, the only out-of-pocket expense is a small program fee. If the entire cost of the the test is covered by insurance, the program fee will not be returned.
