An estimate of how well your pancreas makes insulin using fasting glucose and insulin.
HOMA-Beta is a calculated index, not a separate blood test. It estimates how well the beta cells in your pancreas are producing insulin, using your fasting glucose and fasting insulin.
The formula in SI units is: HOMA-Beta = (20 × fasting insulin in mU/L) ÷ (fasting glucose in mmol/L − 3.5), expressed as a percentage of normal beta-cell function.
Beta cells release insulin to keep blood sugar in range. HOMA-Beta gives a snapshot of how hard those cells are working from a single fasting blood sample, without complex testing.
A high value can mean the pancreas is compensating by overproducing insulin, often an early sign of insulin resistance. A low value can suggest the beta cells are tiring and producing too little, which is seen as diabetes develops.
Aniva reads your result against research-backed ranges, not just the lab's wide normal. The reference shown below is specific to this biomarker.
HOMA-Beta is best read as a trend rather than a fixed cutoff. Around 100% represents normal reference beta-cell function in the original model. Values are not well standardised across labs, populations or insulin assays, so interpret cautiously and alongside HOMA-IR and glucose.
HOMA-Beta depends on accurate fasting insulin and fasting glucose, so it requires a true fasting sample. Insulin assays are not standardised between labs, which limits comparison. It is unreliable in people on insulin therapy and when fasting glucose is near or below 3.5 mmol/L.
Read with its components, fasting insulin and fasting glucose, and alongside HOMA-IR and HbA1c.
What does a HOMA-Beta result mean in simple terms? It estimates how strongly your pancreas is making insulin at rest. Higher means more output; lower means less.
Do I need to fast for this test? Fasting is recommended because the calculation uses fasting glucose and insulin, but follow your lab’s instructions.
What can affect my result? Recent illness, heavy exercise, alcohol, biotin supplements, and some medicines can change glucose or insulin levels.
How often should I check HOMA-Beta? Many people repeat it every 3 to 6 months when monitoring metabolic health or after a treatment change.
How long do results take? Results are usually ready in about 7 days.
What should I discuss with my clinician? Review trends, your glucose, insulin, HbA1c, medications, and whether another test like OGTT or C-peptide would add clarity.
