  • HDL cholesterol:
    • male 0.9 to 1.4 mmol/l
    • female 1.2 to 1.6 mmol/l

  • total cholesterol to HDL:cholesterol ratio
    • positive cardiac risk factor if ratio 4

Patient advice (1)

  • an ideal level of high-density lipoprotein (HDL) is above 1mmol/L. A lower level of HDL can increase your risk of heart disease

  • your ratio of total cholesterol to HDL may also be calculated. This is your total cholesterol level divided by your HDL level. Generally, this ratio should be below four, as a higher ratio increases your risk of heart disease.
