Reference Range
No reference range is reported for urine pH. Although urine pH normally ranges between 6.5 to 8.5 in healthy individuals, it varies with food consumption. Urine with a pH >6.0 is suggestive of alkali contamination or the presence of urea splitting bacteria. In a patient with metabolic acidosis, a urine pH >5.5 suggests a failure of urinary acidification which may indicate renal tubular acidosis.
