JDCM Linked Marker DNA Test
Cheek brushes are now accepted!
Blood samples are preferred as a DNA source. However, in an effort to make JDCM Linked Marker Testing
more convenient and less costly, the University of Pennsylvania will now also accept cheek (cytology) brushes.
Other details:
- Please share the availability of the test with others who are not on the lists.
- Results may take as long as 4-6 weeks depending on the amount of samples received.
- DO NOT call the University for results. It will only interrupt the researchers and slow things down. Test results will ONLY be available by email, fax or snail mail.
- If you supply an email address on the forms, results will be emailed the same day that the certificate is mailed.
