What is BSA?
BSA stands for Body Surface Area It is a measure of the surface area of the human body.
It is used clinically for dosage calculation. This is mainly applied in Chemotherapy, Glucocorticoid dosing, IV Fluid administration, Cardiac Index measurement and one of Renal function Measure of GFR (Glomerular Filteration Rate)
There are many formulae to calculate BSA. Du bois formula and the simplified formula given by Mosteller are the more popular ones.
BSA which is Area is measured in units of sq meter (m 2)
