Formula & Mathematical Methodology: LDL & Lipid Ratios Reference Equation

LDL = TotalChol − HDL − (Triglycerides / 5)
NonHDL = TotalChol − HDL
LDL = TotalChol − HDL − (Triglycerides / 5); NonHDL = TotalChol − HDL

Rounding: Intermediate calculations retain full IEEE-754 floating-point precision; displayed clinical and fitness metrics round to 1 or 2 decimal places.

Worked Example: Benchmark Scenario: LDL & Lipid Ratios

Derive LDL cholesterol, Non-HDL-C, Total/HDL ratio, and TG/HDL ratio.

  1. Enter your current anthropometric, laboratory, or training measurements in the units indicated.
  2. Substitute the values into the reference formula: LDL = TotalChol − HDL − (Triglycerides / 5); NonHDL = TotalChol − HDL.
  3. Compare the primary output and supporting thresholds across all three custom SVG charts.
Result: Evaluates LDL & Lipid Ratios using LDL = TotalChol − HDL − (Triglycerides / 5); NonHDL = TotalChol − HDL.
