How to diagnose high cholesterol
Unfortunately, most people will not experience symptoms of high cholesterol, so the only way to measure blood cholesterol levels is to get a blood test.
“Your GP or practice nurse will take a blood sample, usually by pricking your finger or you might be asked to go for a blood test at your local hospital,” explains the British Heart Foundation (BHF).
According to the BHF, your blood is then checked for levels of good (HDL) cholesterol, bad (non-HDL) cholesterol and triglycerides (another type of blood fat), as well as getting a total cholesterol result.
HDL cholesterol is often dubbed the “good” cholesterol because it counters the harmful effects of LDL cholesterol.
