what is a high cholesterol number
Blood cholesterol is measured in units called millimoles per litre of blood, or mmol/L. As a rough guide, the total levels should be: 5 mmol/L or less for healthy adults. 4 mmol/L or less for those at high risk. LDL levels should be: 3 mmol/L or less for healthy adults. 2 mmol/L or less for those at high risk.
