Frequently Asked Questions
What is Body Surface Area (BSA) and why is it used in medicine?
Body Surface Area is the measured or calculated surface area of a human body. In clinical medicine and oncology, BSA provides a far more accurate physiological index than simple body weight for calculating chemotherapy dosages and cardiac index.
Which clinical BSA formulas are calculated by this tool?
The tool computes BSA using the world’s leading clinical equations: Mosteller (standard worldwide), Du Bois & Du Bois, Haycock, Gehan & George, and Boyd formulas.
What is the standard adult body surface area average?
The average adult male BSA is approximately 1.9 m², and the average adult female BSA is approximately 1.6 m².
