What can cholesterol tests find out?
Cholesterol tests can measure total cholesterol, good cholesterol (HDL), bad cholesterol (called LDL or non-HDL), and triglycerides, which are fatty substances similar to bad cholesterol.
HDL cholesterol helps to clear out cholesterol from the arteries, but LDL cholesterol can cause clogging in arteries.
Cholesterol tests can be carried out at GP surgeries and some pharmacies and will normally involve either a finger prick test or a small blood sample being taken for tests.
As high cholesterol is usually symptomless, cholesterol charity Heart UK recommends all adults go for a cholesterol test to check their levels.
