Calculates urine anion gap (UAG = uNa + uK - uCl) to differentiate distal renal tubular acidosis from GI bicarbonate loss in patients with hyperchloremic non-anion gap metabolic acidosis.
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.

Each component has a specific meaning:
Note: Interpret the urine anion gap result against the clinical thresholds and context described above.
Enter the GI bicarbonate loss in patients for the patient or scenario you are assessing. Calculates urine anion gap (UAG = uNa + uK - uCl) to differentiate distal renal tubular acidosis from GI bicarbonate loss in patients with hyperchloremic non-anion gap metabolic acidosis. Use the urine anion gap result to inform your clinical assessment.
