Heart cholesterol test: what should you know?

A lipid profile commonly reports total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides. These are interpreted together rather than as a diagnosis on their own. The result is considered alongside age, blood pressure, diabetes, smoking, family history, and previous cardiovascular problems. Some people have no symptoms from raised cholesterol, which is why testing may be offered during routine care.

Follow the laboratory's instructions about food, drinks, and regular medicines; do not stop a prescription unless your clinician tells you to. Bring relevant medical and family history to the appointment. Your clinician may suggest changes to eating habits, activity, smoking, or alcohol, then arrange a repeat test when appropriate. If medicine is advised, [Statin Therapy](/treatments/medical-management/statin-therapy/) is one option that may be discussed. Read about the [Cholesterol Test](/treatments/diagnostics-and-screening/cholesterol-test/) itself for preparation details.

A cholesterol test is not an emergency test. Seek urgent help for chest pressure, severe breathlessness, sudden weakness, or trouble speaking, because these symptoms need immediate assessment regardless of a cholesterol result. Arrange routine follow-up if you are unsure how to interpret a result or have not received a plan.

Ask what each part of the result means for you, whether you need a fasting sample, when to repeat testing, and how your overall risk affects the choice between lifestyle changes and medicine.
