Specimen Collection

Acceptable specimens include buccal swab and peripheral blood (EDTA) or saliva. Buccal swabs can be collected by rubbing the inside of the cheeks with a swab (similar to a Q-tip and generally 4 swabs). The swabs are transported to the laboratory in a liquid medium (see manufacturer guidelines for details) or dry swab. Peripheral blood is collected through venipuncture. A minimum of 5-10 ml of whole blood is required. The specimen is collected in a lavender top (EDTA) tube.

Stability (Blood specimens):

  • Ambient: 5 days
  • Refrigerated: 7 days
