Interpreting a canine genetic health test

Read the test identity

Record the laboratory, dog identifier, sample date, variant and result wording. A panel name may cover a changing set of tests, so preserve the actual report rather than a screenshot showing only clear or carrier. Confirm the sample belongs to the right dog before linking it to pedigree or breeding information.

Understand inheritance in context

Different conditions have different inheritance patterns and clinical implications. A one-copy result does not mean the same thing for every test. Use the laboratory’s condition-specific explanation and qualified interpretation rather than applying a general rule learned from another disease. Keep a genetic category separate from examination findings and symptoms.

Respect the limits

OFA’s DNA-test resources distinguish the tested information from broader health records. A negative result for one variant does not rule out all genetic causes, structural disease or an acquired problem. Appropriate imaging or clinical examinations may still be relevant. Do not describe a tested dog as genetically perfect or a whole litter as guaranteed healthy.

Use the result constructively

For breeding, bring both parents’ original reports and family information to the discussion. For medication-sensitive variants, make the result accessible to the treating practice. If reports conflict, contact the laboratory or relevant professional before drawing a conclusion. Keep corrections and revised interpretations with the original evidence. This guide explains record interpretation and does not select a mating or diagnose an individual dog.
