Urine pH
Urine pH measures the acidity or alkalinity of urine and normally ranges from about 4.5 to 8.0, shifting with diet, medications, and acid-base balance. Persistently acidic urine favors uric acid and cystine stone formation, while alkaline urine promotes struvite and calcium phosphate stones and may suggest urinary tract infection with urease-producing bacteria or renal tubular acidosis.
