Why a blood test matters
There are usually no symptoms. Blood testing identifies high cholesterol and helps assess cardiovascular risk.
More details
High cholesterol usually does not cause reliable warning symptoms such as pain or dizziness. A blood test detects it. Over time, it can increase the risk of blocked arteries, heart problems, and stroke. Discuss testing particularly with diabetes, hypertension, or a family history of cholesterol or heart problems.
The test contains more than one number
The profile includes LDL, HDL, triglycerides, and total cholesterol. Results are interpreted with your risk factors.
More details
A lipid panel usually includes total cholesterol, LDL, HDL, and triglycerides. LDL contributes to deposits in arteries, while HDL carries some cholesterol back to the liver. Triglycerides are another blood fat. Your clinician interprets the whole profile with your other risk factors, not just total cholesterol.
When family history matters
Very high LDL can be inherited. Share family history because relatives may need testing.
More details
Very high LDL can be inherited and present from a young age. Tell your clinician about relatives with very high cholesterol or early heart disease. When familial hypercholesterolaemia is diagnosed, parents, siblings, and children may need testing. Food and activity changes alone are often insufficient treatment.
