Calculates eGFR using the 4-variable MDRD Study Equation: 175 × (SCr)^-1.154 × age^-0.203 × 0.742 (females) × 1.212 (Black race), with CKD staging and implications for drug dosing.
BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).
BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.
