Reference range
Reference ranges vary by lab, age and sex. Your own lab report carries the authoritative range, and your clinician reads it with you.
Why it matters
Fasting insulin is one of the most under-ordered and most predictive markers in longevity medicine. Insulin resistance precedes elevated fasting glucose by years; reading insulin alongside glucose is how clinicians catch metabolic dysfunction early enough to reverse it with lifestyle alone.
How REVRCEL clinicians read it
Always read with fasting glucose. HOMA-IR can be calculated for a single-number summary.

Common questions
Why test fasting insulin and not just glucose?
Insulin resistance shows up in insulin years before glucose moves. Glucose-only screening misses the early window.
