Endocrinology medical calculators
All 13 Endocrinology medical calculators on DocMath, A–Z. All specialties
- Adrenal CT washout (absolute & relative percentage washout)Absolute and relative contrast washout of an adrenal mass on an adrenal-protocol CT (unenhanced, enhanced ~60 s, and 15-minute delayed phases).
- Adrenal incidentaloma work-up (ESE/ENSAT 2023: CT category & 1-mg DST)Classifies an adrenal incidentaloma by unenhanced CT attenuation, size and homogeneity, and interprets the 1-mg overnight dexamethasone suppression test, per the 2023 ESE/ENSAT guideline.
- Aldosterone-to-renin ratio (primary aldosteronism screen, Endocrine Society 2025)Interprets a morning seated aldosterone and renin (activity or concentration) against the 2025 Endocrine Society positive-screen definition for primary aldosteronism.
- Burch–Wartofsky Point Scale (thyroid storm)Point scale (BWPS) supporting the clinical diagnosis of thyroid storm in a thyrotoxic patient, from temperature, heart rate, atrial fibrillation, heart failure, GI–hepatic and CNS dysfunction and a precipitating event.
- Calculated free & bioavailable testosterone (Vermeulen)Free testosterone and bioavailable (non-SHBG-bound) testosterone from total testosterone, SHBG and albumin by the Vermeulen mass-action equation.
- CANRISK (Canadian Diabetes Risk Questionnaire)Risk of prediabetes or undiagnosed type 2 diabetes in adults 40 years and older, from questionnaire items (paper-based CANRISK score, 0–86).
- Clinical Activity Score (CAS, thyroid eye disease / Graves’ orbitopathy)Seven-item activity score for Graves’ orbitopathy; CAS ≥3/7 defines active disease (EUGOGO 2021).
- DKA / HHS diagnosis and DKA severity (2024 consensus)Applies the 2024 ADA/EASD/JBDS/AACE/DTS hyperglycaemic-crises criteria to classify DKA (with severity), HHS or mixed DKA/HHS in adults.
- Estimated average glucose from HbA1c (ADAG)Converts an NGSP/DCCT-aligned HbA1c (%) to estimated average glucose in the same units as glucose meters.
- Glucose management indicator (GMI) from CGM mean glucoseApproximate A1C expected from the CGM-derived mean glucose (≥10–14 days of data); compare with the laboratory A1C.
- HOMA-IR & HOMA-%B (Matthews 1985)Insulin resistance and β-cell function estimated from fasting glucose and insulin (original linear approximation).
- LDL cholesterol (NIH / Sampson equation)Calculated LDL-C from a standard lipid panel; more accurate than Friedewald with hypertriglyceridaemia (valid to TG 9.0 mmol/L) and at low LDL-C.
- QUICKI (quantitative insulin sensitivity check index)Insulin sensitivity from fasting glucose and insulin; correlates with the euglycaemic clamp better than HOMA in the derivation study.
