also referred to as DNA Certification, DNA test, DNA Registry. A dog's blood, cheek swab, or other tissue sample is analyzed with a set of 10-15 DNA markers. The results constitute the dog's "DNA fingerprint". When sufficient and informative markers are used, a DNA profile can assign unique identity to each dog, and can be used to identify parentage when combined with the DNA profiles of probable parents. This test does not give information about disease or breed status.
