This ratio is determined by dividing the HDL cholesterol into the total cholesterol. If a person has a total cholesterol of 200 mg/dL and an HDL cholesterol of 40 mg/dL, his or her total/HDL cholesterol ratio would be 5:1. The goal is to keep this ratio below 5:1, with the ideal being below 3.5:1.his ratio is determined by dividing the HDL cholesterol into the total cholesterol.

The test is called the lipoprotein profile and it indicates the total cholesterol levels in your body including HDL and LDL. The ideal total cholesterol level for women without a coronary heart disease should be not less than 200 mg/dL.If the total cholesterol level goes beyond 240 mg/dL then it is considered as high blood cholesterol. Remember even the cholesterol levels at the borderline (200-239 mg/dL) increase the risk of heart disease.tudies indicate that by age 45, most of the women develop high level of total cholesterol (200 milligrams per deciliter mg/dL) than men. It is generally advised that men have a HDL level at or above 40mg/dL and women have their HDL level at a minimum of 50mg/dL.
