The lipid panel with ratios is a comprehensive cardiovascular risk assessment tool measuring total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides, along with calculated ratios such as total cholesterol/HDL and LDL/HDL. These ratios provide additional predictive value for atherosclerotic cardiovascular disease (ASCVD) risk beyond individual lipid fractions alone. The panel is a cornerstone of preventive cardiology and is used to guide risk stratification and therapeutic decision-making. Lipoproteins are complex particles that transport cholesterol and triglycerides through the bloodstream; LDL delivers cholesterol to peripheral tissues and is the primary atherogenic fraction, while HDL facilitates reverse cholesterol transport back to the liver. Triglycerides are stored energy substrates synthesized in the liver and absorbed from dietary fat, transported primarily via VLDL and chylomicrons. The balance between atherogenic (LDL, VLDL) and anti-atherogenic (HDL) particles determines net cardiovascular risk, which is why ratios offer mechanistic insight beyond single values.
A lipid panel with ratios measures different types of fats in your blood and calculates how they compare to each other. These comparisons—called ratios—help your doctor understand your overall risk for heart disease and stroke more accurately than looking at each number separately. A higher ratio of 'bad' cholesterol (LDL) to 'good' cholesterol (HDL) suggests more risk, while a lower ratio is generally healthier. Lifestyle factors like diet, exercise, and weight significantly influence these numbers. Your doctor will look at these results alongside your other health information to get the full picture of your heart health.
When elevated: Elevated total cholesterol/HDL or LDL/HDL ratios indicate an unfavorable balance between atherogenic and protective lipoproteins, associated with increased risk of coronary artery disease, stroke, and peripheral arterial disease. High triglycerides with low HDL (atherogenic dyslipidemia) are strongly linked to metabolic syndrome and insulin resistance. Persistently elevated ratios despite lifestyle modification may warrant pharmacologic evaluation. When low: Low or favorable lipid ratios (e.g., total cholesterol/HDL <3.5) are associated with reduced cardiovascular risk and are generally considered a positive finding. Very low LDL in the absence of treatment may occasionally reflect malnutrition, hyperthyroidism, or hepatic dysfunction and warrants clinical correlation. Extremely low total cholesterol has been associated in some studies with non-cardiovascular conditions including certain malignancies and liver disease.
Lipid ratios are moderately relevant to athletes: sustained aerobic training typically improves HDL and lowers triglycerides, improving ratios and cardiovascular resilience. However, ratios are primarily a long-term health and longevity marker rather than a direct performance predictor; they're most useful for athletes monitoring cardiovascular health status alongside training, especially those with family history of early heart disease or those in endurance sports with high training volume.

The Lipid Panel with Ratios test starts at $18.00 at Quest. No doctor's visit and no insurance needed; we do not bill insurance. Fitomics Insider members pay from $15.00.
Fasting is recommended before the Lipid Panel with Ratios test: fast 9 to 12 hours beforehand (water is fine) so the results are usable. This is not a requirement; it is your choice.
Results for the Lipid Panel with Ratios test are typically ready about 7 days after your draw, and up to 11 days for some samples. Your results land in your Insider portal.
No. When you order the Lipid Panel with Ratios test from Fitomics Research Labs, a licensed physician in our 50-state network reviews and signs your requisition after checkout, and it lands in your portal and inbox. Then visit any Labcorp, Quest, or BioReference patient service center for your draw; results post to your Insider portal.
