What is HDL?
HDL ("good" cholesterol) carries excess cholesterol away from arteries back to the liver for disposal, helping to protect against artery narrowing.
HDL is one of the few blood markers where higher is generally better (up to a point). Regular aerobic exercise is one of the most effective ways to raise HDL.
Why might HDL be high?
Higher HDL is generally considered protective against cardiovascular disease. Very high HDL (above 100 mg/dL) can occasionally be seen with certain genetic conditions, but mildly high values are typically a positive finding.
This information is educational. A single out-of-range result is rarely the whole picture — a healthcare professional can interpret your numbers alongside your overall health and history.
Context questions that matter
- →Was this result slightly or clearly outside the reference range?
- →Were related markers also high or low?
- →Is this new compared with previous tests?
- →Could recent illness, exercise, fasting, alcohol, supplements, or medication affect it?
- →Do you have symptoms that should be discussed with a clinician?
Markers often reviewed together with HDL
Clinicians rarely look at one number in isolation. These markers usually accompany HDL on a lipid panel panel and help put the result in context.
Lifestyle considerations
- •Aerobic exercise is one of the most effective ways to raise HDL
- •Quitting smoking and reducing refined carbohydrates can also improve HDL levels
Questions to ask your doctor
- →What does this mean together with LDL, HDL, triglycerides, non-HDL cholesterol and ApoB if available?
- →Should this be repeated fasting, or interpreted with my overall cardiovascular risk?
- →Are family history, blood pressure, glucose or other risk factors important here?
Don't guess from one flagged result.
Start with the most relevant panel and see how your markers fit together in plain English.
Frequently asked questions
What does high HDL mean?
+
Higher HDL is generally considered protective against cardiovascular disease. Very high HDL (above 100 mg/dL) can occasionally be seen with certain genetic conditions, but mildly high values are typically a positive finding.
What is HDL?
+
HDL ("good" cholesterol) carries excess cholesterol away from arteries back to the liver for disposal, helping to protect against artery narrowing.
Is one cholesterol marker enough to understand cardiovascular risk?
+
Usually no. LDL, HDL, triglycerides, non-HDL cholesterol and ApoB (when available) are read together with age, blood pressure, glucose, smoking status and family history. A single marker rarely tells the whole story.
Should lipid results be fasting?
+
Many lipid markers can be interpreted non-fasting, but triglycerides and some follow-up decisions may depend on fasting status. Check the lab's note on the report, or ask your doctor whether your specific test was meant to be fasting.
What supports healthy HDL levels?
+
Aerobic exercise is one of the most effective ways to raise HDL. Quitting smoking and reducing refined carbohydrates can also improve HDL levels
