Cholesterol & Heart Health
Cholesterol and triglycerides are blood lipids. Their levels form part of a broader cardiovascular risk assessment.
Why is this important?
Understanding the purpose and limits of laboratory information can support a more informed conversation with a qualified healthcare professional.
How laboratory testing relates
A lipid assessment may include total cholesterol, LDL, HDL, and triglycerides. Results are interpreted with age, health history, blood pressure, smoking, diabetes, and other factors.
Before testing
Preparation is test-specific. Follow the instructions given for the exact test and contact the laboratory if fasting, timing, medicines, or specimen collection is unclear. Do not stop medicines unless a qualified professional tells you to.
