The HDL-C test assesses your risk for cardiovascular diseases by measuring high-density lipoprotein cholesterol, which is beneficial for heart health. This test is often part of a lipid panel that also includes total cholesterol, LDL cholesterol, and triglycerides. Regular screening can detect potential heart issues early, especially if you have risk factors like high blood pressure or diabetes. It is a routine procedure for both children and adults without cardiovascular symptoms. Regular cholesterol level checks help identify potential concerns at an early stage.
Monitoring cholesterol levels over time is crucial in patients with a history of prior abnormal cholesterol where ongoing testing is essential to track lipid profiles. It is also essesntial after initiating any cardiovascular risk reduction treatment where lifestyle changes or medications are recommended to improve cholesterol levels, ongoing testing helps assess the response to the prescribed treatment.
HDL-C testing is recommended for adults with risk factors such as smoking, high blood pressure, diabetes, or a family history of heart disease, children with a family history of high cholesterol or heart disease, individuals with a prior diagnosis of heart disease or abnormal cholesterol levels and patients starting treatment to reduce cardiovascular risk.
The test involves drawing a blood sample, typically from a vein in your arm, in a procedure called venipuncture. For accurate results,especially if measuring LDL cholesterol as well, fasting for up to 12 hours maybe required. At-home tests involve a finger prick to collect a small blood sample.
HDL-C results are reported in milligrams per deciliter(mg/dL). A higher HDL-C level is desirable. Above 60 mg/dL is excellent and associated with lower cardiovascular risk and below 40 mg/dL (or 50 mg/dL in females) is considered low and increases the risk of heart disease and stroke. Your doctor will also consider your total cholesterol, LDL levels, and other health factors to provide a comprehensive assessment.
If your HDL-C levels are low or if you have other cardiovascular risk factors, your doctor may recommend lifestyle changes like adopting a heart-healthy diet, increasing physical activity, quitting smoking, and reducing alcohol intake. You may be provided medications like statins or other cholesterol-lowering drugs to improve your lipid profile. Regular follow-up tests will be required to track your cholesterol levels and adjust treatments as necessary. Discussing your HDL-C test results with your doctor can help you understand your cardiovascular health and take proactive steps to reduce your risk of heart disease.
