Exceptions: Tests for which buccal swabs are not accepted include GenomeSeqDx, XomeDx®Insights, XomeDxXpress®, and Congenital Sideroblastic Anemia. Multiple permitted tests can be ordered on one swab but the DNA yield is limited and additional specimens may be needed to complete testing. For more information email zebras@genedx.com.
Buccal swabs are not accepted if the patient has ever received an allogeneic bone marrow transplant/stem cell transplant due to the potential for a high percent of donor DNA to be present. Cultured fibroblasts are required. GeneDx can provide a punch biopsy kit and can culture fibroblasts on site, as needed.
 Kits: Complimentary buccal swab kits are available for US and Canadian clients. To order kits, please visit www.genedx.com/supplies or email zebras@genedx.com. Contents include sponge swab, transport tube with tinted stabilizer solution, label for tube, and shipping box.
