Which BSA formula is most accurate?

The Mosteller formula is most commonly used in clinical practice due to its simplicity and good accuracy. The DuBois formula is the original and still widely used, while Haycock may be more accurate for children.

Why is BSA used for drug dosing?

BSA correlates better with metabolic rate and organ function than weight alone, making it more accurate for dosing medications, especially chemotherapy drugs where precise dosing is critical.
