Assess your diabetes risk with this screening tool

A tool that calculates the likelihood of developing type 2 diabetes based on various risk factors.

A tool to assess diabetes risk and provide screening recommendations.

A decision-tree style helper that suggests the likely diabetes type based on obesity, ketosis, and initial treatment.

Convert between A1C (DCCT/IFCC) and estimated average glucose (mg/dL / mmol/L). Type any one value; the rest auto-calc.

Estimate insulin resistance from fasting insulin (mIU/L) and fasting glucose (mmol/L).

Compute LPIR (0–100) from NMR lipoprotein measures: VLDL size/particles, LDL size/small LDL-P, HDL size/large HDL-P.

Estimate insulin sensitivity from fasting insulin (μIU/mL) and glucose (mg/dL).

Estimate 7.5-year diabetes risk from age, BMI (via height/weight), labs, BP, sex, ethnicity, and family history.

Correct serum sodium for hyperglycemia using Emmett (2013). Supports mg/dL or mmol/L glucose.

Correct serum sodium for hyperglycemia using Hillier (1999): Na + 0.024 × (glucose − 100).

Correct serum sodium for hyperglycemia using Katz (1973): Na + 0.016 × (glucose − 100).

Estimate 5-year fracture risks using clinical factors plus BMD T-score.

Estimate 5-year fracture risks using clinical factors and age (no BMD T-score).

Dx requires insulin resistance (IGT or IFG) + at least one other: BMI ≥25, TG/HDL, BP ≥130/85, glucose IGT/IFG (not DM), or other IR features.

1 point each: abdominal obesity, TG, HDL, BP, fasting glucose (or on Rx). Metabolic syndrome present if total ≥3.

1 point each: abdominal obesity, TG ≥150, low HDL, BP ≥130/85, fasting glucose ≥110. Metabolic syndrome present if total ≥3.

Dx requires plasma insulin >75th percentile + ≥2 of: abdominal obesity, TG/HDL abnormal, BP ≥140/90 or on Rx, glucose IGT/IFG (not DM).

Required: abdominal obesity (population-specific waist) + ≥2 of: TG ≥150 or Rx, low HDL (sex-specific) or Rx, BP ≥130/85 or Rx, glucose ≥100 or DM.

Required: insulin resistance (IGT, IFG, T2DM, or reduced sensitivity) + ≥2 of: abdominal obesity, dyslipidemia, high BP, microalbuminuria.

Fracture Index is a measure of fracture risk that incorporates Bone Mineral Density (BMD)—a known indicator of bone strength—together with risk factors, age band, and BMD T-score to estimate 5-year nonvertebral, hip, and vertebral fracture risks.

Fracture Index estimates fracture risk using clinical risk factors and age, without requiring Bone Mineral Density (BMD).

ORACLE combines Age, BMI, HRTx, prior fracture, and UBPI into a single risk estimate; thresholds: ≤0.26 lower risk, 0.26–0.32 high risk (50% spec), >0.32 high risk (sens 76%).

ORAI uses Age, Weight, and Estrogen use to select women for bone densitometry. Score ≥9 → higher risk.

SCORE = Race + Rheumatoid Arthritis + Fracture history + Estrogen + (3×Age/10) − (Weight/10). Bands: 0–6 Low, 7–15 Moderate, ≥16 High risk.

OST = 0.2 × (Weight − Age). Bands: −20 to −1 High risk; −1 to 3 Moderate; 4 to 20 Low.

OST = 0.2 × (Weight − Age). Bands: −20 to −4 High, −3 to 1 Moderate, >1 to 20 Low.
