Fasting Blood Test Values

These values come from a fasting blood test (8-12 hours of fasting). You can request a fasting glucose + insulin panel from your doctor or use home test kits.

Glucose Units

Fasting Blood Glucose (mg/dL)

Normal fasting glucose: 70-99 mg/dL

Fasting Insulin (µIU/mL)

Normal fasting insulin: 2-20 µIU/mL. Optimal: below 8 µIU/mL.

HOMA-IR Result

Enter your fasting blood test values and click Calculate.

About Insulin Resistance Calculator (HOMA-IR)

Calculate your HOMA-IR score - the gold standard clinical formula for estimating insulin resistance. Uses only two fasting blood values (glucose and insulin) to assess your metabolic health status and diabetes risk.

Key Features

HOMA-IR formula: (fasting glucose × fasting insulin) / 405
QUICKI index as secondary insulin sensitivity metric
Five-tier interpretation from Optimal to Severe Resistance
Supports mg/dL (US) and mmol/L (UK/EU/AU) glucose units
Personalized intervention advice ranked by HOMA-IR severity
Based on the clinically validated Homeostatic Model Assessment (Matthews et al.)

Use Cases

Interpret fasting blood test results from your doctor
Track insulin sensitivity improvement during intermittent fasting
Screen for prediabetes risk before seeing a doctor
Monitor response to dietary changes (low-carb, IF, exercise)
Understand why IF works - it directly lowers HOMA-IR scores
