A normal lab report only tells you whether a single value is in or out of range. Predictive indices look across multiple markers to calculate your actual disease risk - years before symptoms appear.
Your report computes 17 of these indices automatically, including HOMA-IR, FIB-4, and Framingham CVD risk. No extra tests needed.

Frequently Asked Questions
What are predictive clinical risk indices in a blood test report?
Predictive clinical risk indices are validated formulas derived from blood biomarkers that quantify your risk for specific conditions. For example, HOMA-IR predicts insulin resistance, FIB-4 predicts liver fibrosis risk, and the Framingham Cardiovascular Score estimates your 10-year heart disease probability — all computed from your standard blood test without any extra panels.
What is HOMA-IR and what does it mean?
HOMA-IR (Homeostatic Model Assessment of Insulin Resistance) is calculated as (Fasting Insulin × Fasting Glucose) / 405. A value above 2.5 indicates insulin resistance, which is a precursor to Type 2 diabetes even when fasting glucose appears normal. It is one of the most clinically useful indices for detecting early metabolic disease before it shows up in standard tests.
How many risk indices does Smart Health Report calculate?
Smart Health Report computes 17 validated clinical indices: HOMA-IR, FIB-4 (liver fibrosis), Framingham CVD Score, TyG Index (insulin resistance), AIP (atherogenic index of plasma), NLR (neutrophil-to-lymphocyte ratio), eGFR (kidney function), Uric Acid Risk Index, and 9 more — all derived from your standard blood test data, each with peer-reviewed citations.
