In certain cases, other metrics might be more appropriate:
- Body Weight: While less precise, body weight is often used when BSA calculations are impractical or unnecessary.
- Body Mass Index (BMI): BMI is sometimes used as a supplementary tool to BSA, especially in populations where body composition plays a significant role in drug metabolism.
- Allometric Scaling: This method considers the size and metabolic rate differences across species and is often used alongside BSA in toxicological assessments.
