Lipid Panel & Ratios
Enter your cholesterol and triglyceride values. See not just where each number falls, but the ratios that actually reveal your metabolic risk.
Your lipid panel
Enter the four values from your most recent fasting lipid panel.
What this means
What to consider
Medications that may affect your results
Statins (atorvastatin, rosuvastatin) lower LDL and triglycerides, and may modestly raise HDL. Your unmedicated lipid profile would likely show higher LDL and TG values.
Fibrates (fenofibrate, gemfibrozil) primarily lower triglycerides and can raise HDL. If you are on a fibrate, your TG:HDL ratio reflects the medicated state.
Niacin (vitamin B3 at therapeutic doses) raises HDL more than most other interventions and lowers TG.
Fish oil / Omega-3 (prescription or supplement) lowers triglycerides. Effect is dose-dependent.
If you are taking lipid-modifying medications, your results reflect the medicated state. Discuss trends and targets with your healthcare provider.
About this tool
Ratio Formulas
TC:HDL = Total Cholesterol / HDL. LDL:HDL = LDL / HDL. TG:HDL = Triglycerides / HDL.
All ratios calculated in mg/dL. If entered in mmol/L, values are converted first (cholesterol ×38.67, triglycerides ×88.57).
Optimal Thresholds (mg/dL)
TC:HDL — optimal below 3.5, borderline 3.5-5.0, elevated above 5.0.
LDL:HDL — optimal below 2.5, borderline 2.5-3.5, elevated above 3.5.
TG:HDL — optimal below 2.0, borderline 2.0-3.0, elevated above 3.0 (this ratio is the strongest lipid-based proxy for insulin resistance).
Known Limitations
Reference ranges can vary by lab. LDL is typically calculated via the Friedewald equation and may be inaccurate when triglycerides exceed 400 mg/dL. A single lipid panel is a snapshot; trends over time are more meaningful. Fasting state (8-12 hours) recommended for accurate triglyceride values.
