Estimate your Body Mass Index (BMI) by using the chart below. Consult your physician to obtain a more accurate value.
BMI is a measure of your body shape based on your weight and height. When mass is measured in pounds, and height is measured in inches, it can be calculated with the following formula:
BMI = 703 x (mass/height2).
A potential donor with a BMI greater than 28 will need to undergo additional testing to determine if donation will cause them harm. The chart above is to be used for estimation purposes only.
