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.
