Lithium Renal Clearance as Fraction of GFR

Calculate lithium renal clearance as a percentage of GFR to assess tubular reabsorption efficiency and predict lithium accumulation risk in patients with chronic kidney disease.

Clinical Guidance

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.
