Formula & Mathematical Methodology: TyG Index & Atherogenic AIP Formula

TyGIndex = ln( (TriglyceridesmgdL × FastingGlucosemgdL) / 2 )
TGtoHDL = TGmgdL / HDLmgdL
TyG_Index = ln( (Triglycerides_mg_dL × FastingGlucose_mg_dL) / 2 ); TG_to_HDL = TG_mg_dL / HDL_mg_dL
  • fastingTriglyceridesMgDl: Fasting Triglycerides Mg Dl (mg/dL)
  • fastingGlucoseMgDl: Fasting Glucose Mg Dl (mg/dL)
  • hdlCholesterolMgDl: Hdl Cholesterol Mg Dl (mg/dL)

Rounding: Clinical scores round to statutory integer or decimal precision; physiological metrics round to 2 decimal places.

Worked Example: Clinical / Physiology Scenario: TyG Index & Atherogenic AIP

Evaluate cardiometabolic insulin sensitivity via TyG Index, TG/HDL ratio, and AIP.

  1. Enter lab values, anthropometric measurements, or performance test metrics.
  2. Evaluate the reference equation: TyG_Index = ln( (Triglycerides_mg_dL × FastingGlucose_mg_dL) / 2 ); TG_to_HDL = TG_mg_dL / HDL_mg_dL.
  3. Inspect the primary classification, supporting indices, and 3 SVG charts.
Result: Computes TyG Index & Atherogenic AIP via TyG_Index = ln( (Triglycerides_mg_dL × FastingGlucose_mg_dL) / 2 ); TG_to_HDL = TG_mg_dL / HDL_mg_dL.

Frequently Asked Questions

How does the Triglyceride-Glucose (TyG) Index & Atherogenic Index of Plasma (AIP) Calculator compute its result?

It evaluates TyG_Index = ln( (Triglycerides_mg_dL × FastingGlucose_mg_dL) / 2 ); TG_to_HDL = TG_mg_dL / HDL_mg_dL directly in your browser and updates three custom SVG visualizations in real time.

Can I use Goal Seek to solve backwards for a target lab value or pace?

Yes. Click "🎯 Goal Seek" in the results toolbar to solve backwards for any numeric input parameter.

Are my health and biometric inputs kept private?

Yes. All calculations run 100% locally on your device with zero external transmission.

Triglyceride-Glucose (TyG) Index & Atherogenic Index of Plasma (AIP) Calculator: inputs, method, and how to read the result

Evaluate cardiometabolic insulin sensitivity via TyG Index, TG/HDL ratio, and AIP.

Choose inputs for the case you are checking

The defaults are illustrative. Replace them with values for your case and keep the units shown beside each field.

  • Fasting Triglycerides Mg Dl: Fasting Triglycerides in mg/dL.
  • Fasting Glucose Mg Dl: Fasting Plasma Glucose in mg/dL.
  • Hdl Cholesterol Mg Dl: HDL Cholesterol in mg/dL.

What the calculation includes

With the default values shown, Triglyceride-Glucose (TyG) Index is 8.85 TyG. The calculation follows TyG Index & Atherogenic AIP Formula; the formula and variable definitions above show how the inputs combine.

One-input check: With the other defaults held constant, changing Fasting Triglycerides Mg Dl from 145 mg/dL to 160 mg/dL changes Triglyceride-Glucose (TyG) Index from 8.85 TyG to 8.95 TyG. This is a comparison inside the calculator's stated model, not a prediction.

Where to use caution

  • Uses peer-reviewed clinical and sports physiology formulas.
  • For educational and informational reference only; clinical scores do not replace physician judgment or laboratory reference ranges.

Scope: Global Clinical & Sports Science Consensus Check the assumptions and limitations against your situation before relying on the estimate.
