Shows the balance between “bad” LDL and “good” HDL cholesterol to help frame heart health.
The LDL to HDL ratio is a calculated value, not a separate blood test. It compares LDL cholesterol, which can build up in artery walls, with HDL cholesterol, which helps clear cholesterol away.
The formula is: LDL cholesterol ÷ HDL cholesterol, in the same units.
Cardiovascular risk depends not just on how much LDL you have but on the balance between harmful and protective cholesterol. This ratio captures that balance in a single number.
A higher ratio means LDL outweighs protective HDL, which is linked with greater risk of atherosclerosis and heart disease. 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, which vary by lab and overall risk:
These are general guides. Modern guidelines focus more on absolute LDL and non-HDL targets, so read the ratio with a clinician.
LDL is often calculated and becomes unreliable when triglycerides are high. Both components are affected by recent meals and by lipid-lowering medication. Acute illness can temporarily lower cholesterol and distort the ratio.
Read with its components, LDL and HDL cholesterol, and alongside total cholesterol, triglycerides and non-HDL cholesterol.
What does my LDL/HDL ratio mean? A higher ratio suggests more LDL relative to HDL, which is less favorable. A lower ratio suggests a more favorable balance; always interpret with your full lipid panel.
Do I need to fast for this test? Fasting is usually not required, but follow your lab’s instructions. Keeping the same preparation each time helps compare results.
What can affect the result? Recent fatty meals, alcohol, illness, hard workouts, dehydration, pregnancy, and medicines or supplements that change lipids can all shift the ratio.
How often should I check it? Many people check along with routine cholesterol tests. Your clinician may suggest a repeat after lifestyle changes or medication adjustments.
How long do results take? Results are usually ready in about 7 days.
What should I discuss with my clinician? Talk about LDL-C, non-HDL-C, and ApoB, your overall risk, and simple steps to improve heart health.
