Testing & genetics / SOURCE BRIEF

An out-of-range result is not a diagnosis.

Patient educationSource dated Sep 4, 2025Curated Sep 21, 2026

What to know

Reference ranges describe results in comparison groups. A result outside the range does not automatically mean disease, and a result inside it does not rule out a problem. History, symptoms and other findings matter.

Points to carry forward

  • Use the range printed on your own report.
  • Ask your clinician what the result changes and whether follow-up is needed.

Keep this in mind

Laboratories may use different methods, ranges and units. This brief cannot interpret your individual results.
