Also known as a Buccal Swabs (pronounced like "buckle")....

Cheek swabs are the act of gently rubbing the inside of the mouth with a cotton tipped swab to collect cells for dna testing.

DNA test results, when performed by an AABB Certified lab are often accurate enough to be recognized as definitlve evidence of a family relationship

A legal dna test required by the courts includes a documented chain of custody, where the cheek swab dna sample is accounted for, from the collection to the lab.

Mobile DNA collections with the proper dna custody chain allow labs to issue reports for immigration application requests.
