A simple ratio comparing triglycerides to HDL cholesterol, adding context to heart and metabolic health.
The triglyceride to HDL cholesterol ratio (TG/HDL) is a calculated value, not a separate blood test. It compares triglycerides, a type of fat in the blood, with HDL cholesterol, the protective cholesterol.
The formula is: triglycerides ÷ HDL cholesterol, in the same units.
A high triglyceride level combined with low HDL is a hallmark of insulin resistance and metabolic dysfunction. The TG/HDL ratio captures this pattern in one number and is often used as a simple, low-cost marker of insulin resistance and cardiometabolic risk.
A higher ratio points toward insulin resistance, small dense LDL particles and greater cardiovascular risk. A lower ratio is more favourable.
Aniva reads your result against research-backed ranges, not just the lab's wide normal. The reference shown below is specific to this biomarker.
Interpretive thresholds in SI units (mmol/L), which vary by population:
In conventional units (mg/dL) the common cutoff for higher risk is around 3 or above. Cutoffs differ by sex and ethnicity, so read with a clinician.
Triglycerides rise sharply after eating and vary day to day, so a fasting sample gives the most stable result. The thresholds differ between ethnic groups, performing less well in some populations. Alcohol and lipid-lowering medication also affect both components.
Read with its components, triglycerides and HDL cholesterol, and alongside fasting glucose, HOMA-IR and the full lipid panel.
What does the triglyceride/HDL ratio show? It compares triglycerides to protective HDL. Higher results may point toward insulin resistance or a more atherogenic pattern.
Are there standard cutoffs? No. This measure is not guideline-endorsed; no standardized cutoffs. Interpret with your full lipid panel and overall risk.
Do I need to fast? Fasting is not required for most people. If triglycerides are high or variable, your clinician may repeat a fasting lipid panel.
What can affect my result? Recent sugary or fatty meals, alcohol, hard exercise, illness, pregnancy, dehydration, and some medicines can change triglycerides or HDL.
How often should I test? Many people check lipids yearly or as advised. Recheck sooner after lifestyle changes or if results shift unexpectedly.
How long do results take? Results are usually ready in about 7 days. Your report will show both triglycerides and HDL used to calculate the ratio.
