Tested on Gulf Medical Boards (DHA, SMLE, MOH & HAAD)
Clinical calculations and diagnostic scoring systems like HOMA-B frequently appear on Prometric exams. Master high-yield clinical vignettes with instant AI-powered pathophysiology rationales.
What is the HOMA-B?
The HOMA-B is an evidence-based clinical decision rule engineered to quantify diagnostic probability, stratify clinical severity, and guide therapeutic decision-making in endocrinology & metabolism practice. The Homeostatic Model Assessment of Beta-cell function (HOMA-B) estimates the steady-state beta-cell function as a percentage of a normal healthy reference population. Clinical scoring tools like HOMA-B are essential in acute and outpatient management, enabling clinicians to objectively differentiate between low-risk candidates suitable for conservative therapy and high-risk patients requiring urgent interventions. Verified against current 2026 clinical standards, this tool is extensively tested on Gulf health authority licensing exams including DHA (Dubai), SMLE (Saudi Arabia), MOH, HAAD/DOH (Abu Dhabi), OMSB (Oman), and QCHP (Qatar).
💡Clinical Pearls & Diagnostic Utility
Helps distinguish whether hyperglycemia is primarily driven by insulin resistance (high HOMA-IR) or beta-cell failure (low HOMA-B).
Formula & Calculation Parameters
The mathematical equation and clinical variables required to calculate HOMA-B:
Score Interpretation & Clinical Stratification
| Score Range | Clinical Interpretation | Risk Tier |
|---|---|---|
| ≤ 50 | Low Beta-Cell Function | red |
| 50 – 100 | Borderline to Normal | yellow |
| ≥ 100 | Normal/High (Compensatory) | green |
When to Exercise Caution
Not valid if fasting glucose is ≤ 63 mg/dL. Not validated for use in patients receiving exogenous insulin therapy. Less accurate in severe hyperglycemia (glucose toxicity).
