Enter Lab & Clinical Values

IDF 2005 + CKM 2026 · Fasting lab values required · mg/dL units

All calculations are local — no patient data stored. Fasting lipid panel required for accurate TG & FPG values.
Ethnicity (waist cutoffs)
Sex
Waist Circumference (cm) MANDATORY IDF GATE Measured at navel level, standing, after gentle expiration. This is the required central obesity criterion — without it, IDF MetS cannot be diagnosed regardless of other criteria.
📌 IDF South Asian — ♂: ≥90 cm diagnostic · ♀: ≥80 cm diagnostic | Caucasian — ♂: ≥102 cm · ♀: ≥88 cm
Fasting Triglycerides (mg/dL) Fasting sample required. AHA 2026: TG ≥150 triggers PREVENT-ASCVD risk estimate + ApoB measurement recommendation. mmol/L × 88.57 = mg/dL
On TG-lowering medication?
HDL Cholesterol (mg/dL) AHA 2026: In MetS/CKM, Non-HDL-C and ApoB are preferred over LDL-C. Enter Total Cholesterol too for auto-calculation of Non-HDL-C.
📌 Non-HDL-C = TC − HDL-C (AHA 2026 preferred marker)
On HDL-raising medication?
📌 CKM targets use LDL-C. Friedewald may underestimate if TG ≥150.
Blood Pressure (mmHg) IDF MetS criterion: ≥130/85 mmHg or antihypertensive treatment. ESC 2024 "Elevated BP" = 130–139/85–89 mmHg also flagged.
On antihypertensive medication?
Fasting Plasma Glucose (mg/dL) 8-hour fast required. IDF criterion: ≥100 mg/dL (5.6 mmol/L). Prediabetes 100–125 · Diabetes ≥126. mmol/L × 18.02 = mg/dL
📌 Prediabetes 5.7–6.4% · Diabetes ≥6.5%
On antidiabetic medication?
Renal Markers (CKM Staging) CKD advances CKM stage from 1→2. Microalbuminuria (urine ACR >30 mg/g) is a CKM Stage 2 indicator and adds +2 risk amplifier points per AHA 2026.
Established CVD / Prior Event Prior MI, stroke, TIA, PCI, CABG, or known coronary/peripheral artery disease classifies patient as CKM Stage 4 if MetS/DM/CKD is also present.
Risk Amplifiers Select all that apply. Non-diagnostic but clinically scored per AHA 2026 CKM framework. Lp(a) ≥125 nmol/L carries 40% increased ASCVD risk — AHA 2026 mandates one-time screening in all adults.

⚕️ Metabolic syndrome diagnosis requires clinical confirmation. Lab values (fasting TG, HDL-C, FPG) must be from a certified laboratory after ≥8-hour fast. This tool uses IDF 2005 criteria with South Asian waist cutoffs and AHA/ACC 2026 CKM staging. Non-HDL-C and ApoB targets per AHA 2026 COR 1 recommendations. It does not replace clinical judgment, physician diagnosis, or pharmacotherapy decisions. Use Martin-Hopkins or Sampson-NIH equation for LDL-C when TG ≥150 mg/dL.
