Healthy cholesterol levels have been defined by the NHS as the following:
– Total cholesterol: 5 mmol/L or below
– HDL (good cholesterol): 1 mmol/L or above
– Non-HDL including LDL (bad cholesterol): 4 mmol/L or below
– Fasting triglycerides (when you’re asked not to eat for several hours before the test): 1.7 mmol/L or below
– Non-fasting triglycerides (when you eat as normal before the test): 2.3 mmol/L or below
Note that different laboratories will have slightly different normal reference ranges for these measurements.
