HOMA-β
A calculated estimate of pancreatic beta-cell function.
What is it
HOMA-β is a calculated index derived from fasting glucose and fasting insulin that estimates pancreatic beta-cell function — the body's capacity to produce insulin.
Why it's measured
HOMA-β has been used in research to evaluate insulin secretion alongside HOMA-IR.
Reference range
Standard laboratory reference
Context-dependent index
Reference ranges vary by laboratory. Your individual reference range will appear on your test report and should be interpreted by your physician in the context of your overall health profile.
What results may indicate
Elevated
May reflect compensatory insulin overproduction in early insulin resistance — interpretation requires clinical context.
Lower
May reflect reduced beta-cell function in research literature.
These associations are general. They are not a personal diagnosis or prediction. Discuss your individual results with your physician in the context of your full health profile.
When it's measured
Calculated from fasting glucose + fasting insulin.
