Other Recognized Accreditation
Details of Other Accreditation
ISAG certificates for International Comparison Tests for Parentage Testing (rank 1). Accredited VGL-Forensics; Forensic nuclear and mitochondrial DNA testing in animals
Lab SOP details
All diagnostic tests (traits and diseases) are strictly validated for performance prior to release to public. Quality control for customer samples include duplicate testing with independent DNA extractions, tagging of tested samples with ID markers and matched results. Positive controls for expected results for all tests. Negative control for all tests. Parentage exclusions verified via retesting of samples involved in case.
ISAG Parentage Panel Used
Other Parentage Testing Details
SNP panel; Owner or veterinarian when required. Buccal brushes are primary type of sample. Other types of samples also processed.
