What should you know about a lipid profile basic test?

The panel commonly includes total cholesterol, HDL cholesterol, LDL cholesterol and triglycerides. These particles have different roles: LDL can contribute to fatty deposits in artery walls, while HDL helps carry cholesterol away for processing. Triglycerides are another form of fat carried in the blood. One result does not tell the whole story. Age, blood pressure, diabetes, smoking, family history, kidney health and medicines can change how a clinician interprets the panel.

Follow the laboratory or clinician’s instructions about food, drinks and medicines. Some lipid tests can be taken without fasting, while a fasting sample may be requested for particular questions or an unexpectedly high triglyceride result. Do not stop prescribed medicine unless the prescriber tells you to. Keep a record of recent illness, major diet changes and supplements, because these details may help explain a result. Your clinician may suggest a repeat test, lifestyle changes or a treatment discussion such as statin therapy.

Arrange routine follow-up if the report is outside the range shown by the laboratory, or if you have been asked to review cardiovascular risk. Seek urgent help for chest pressure, severe breathlessness, fainting or sudden weakness, because these symptoms need assessment regardless of a lipid result.

Ask which lipid value needs attention, what your overall cardiovascular risk means, whether the sample needed fasting, and when a repeat test is appropriate.
