4. Recommended Ranges
HDL cholesterol used to be measured through the separation of other lipoproteins through chemical precipitation with divalent ions and coupling it with a cholesterol oxidase reaction or ultracentrifugation. The newer method still uses a combination of the older techniques.
Per the American Heart Association, National Institute of Health, and National Cholesterol Education Program, a level of lower than 1.03 mmol/L is low and the patient has a higher risk of heart disease. Levels between 1.03 mmol/L and 1.55 mmol/L is considered medium. Levels above 1.55 mmol/L is considered to be high and optimal as it decreases the risk of heart disease.
