Urine pH
Panel: Urinalysis & Urine Tests · All urinalysis tests
Typical adult reference range
| Conventional units | 4.5–8.0 |
| SI units | — |
Ranges vary between laboratories and methods — compare your result with the range printed on your own report.
What a high or low result can mean
High urine ph: high values can be seen with some urinary infections, a vegetarian diet, and certain kidney tubular disorders.
Low urine ph: low values may occur with a high-protein diet, diarrhea, or metabolic acidosis.
These are associations, not a diagnosis: the same result can have several causes, and your clinician interprets it with the rest of your results and history.
◆ Kidney note
This test is closely tied to kidney health, and it is one a kidney specialist (nephrologist) watches closely. On this site, kidney-related results are a special focus: see the kidney and dialysis medicines in our Drug Guide and the kidney condition hubs for the wider picture.
