How to Calculate HDL Ratio
- 1). Get your blood test results or obtain cholesterol data from your chart or physician. The cholesterol level is given in milligrams per 100 milliliters (1 deciliter) of blood, or mg/dL.
- 2). Look for the LDL ("bad") cholesterol value in the report. For instance, say that the LDL equals 150 mg/dL.
- 3). Find the HDL ("good") cholesterol value. As an example, your good cholesterol, HDL, is 90 mg/dL.
- 4). Divide the HDL value by the LDL level to obtain the ratio. For the numbers in the example, the HDL/LDL ratio is 90 / 150 = 0.6.
- 5). Analyze the HDL/LDL ratio; the values below 0.3 represent a risk factor for heart diseases, while values above 0.4 are optimally good.
