Which BSA formula is most accurate?

The Mosteller formula (√(H×W/3600)) is simplest and widely used. DuBois and Haycock are more accurate for extreme body sizes.

When is BSA used in medicine?

BSA is used for chemotherapy dosing, cardiac index calculation, glomerular filtration rate, pediatric dosing, and nutritional support.

Average adult BSA is approximately 1.7-1.8 m² (1.73 m² for a standard 70 kg, 170 cm adult).

Calculate BSA using Mosteller formula (√(height×weight/3600)) and DuBois formula — essential for drug dosing.
