What should you know about a cholesterol blood test?

A lipid or cholesterol panel may include total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides. These substances help the body in different ways, while an excess of some blood fats can contribute to fatty deposits inside arteries. The report is read using the laboratory range and the pattern of results, not one number alone.

Your clinician may also consider age, blood pressure, smoking, diabetes, family history, kidney health and previous cardiovascular problems. A cholesterol result does not diagnose Anaemia, Brucellosis, Chronic Fatigue Syndrome, Chronic Kidney Disease, Coeliac Disease, Crohn's Disease, Dengue Fever or Glandular Fever.

Ask whether fasting was needed for your particular panel and follow the laboratory's instructions for future samples. Share your medicines, supplements, diet pattern, activity level and family history. Lifestyle advice may include changing the balance of foods, regular movement, stopping smoking and managing related conditions. If medicine is recommended, discuss how it works, how it is monitored and what to do if side effects appear; do not stop it independently.

A cholesterol result is usually not an emergency by itself. Seek urgent help for chest pressure, severe breathlessness, sudden weakness on one side, trouble speaking or sudden loss of vision, because these symptoms may signal an acute cardiovascular problem. Arrange routine follow-up to review an unexpected result or a strong family history of early heart disease.

Ask which parts of the panel need attention, what your overall cardiovascular risk means, whether a repeat test is useful, and how food, activity or medicine could change the plan.
