Urine pH
Urine pH tells how acidic or alkaline the urine is. It depends on diet, metabolism and kidney function; it helps in understanding stones and certain metabolic conditions.
| Rating | Range | What it means |
|---|---|---|
| Worth improving | below 5 | Acidic urine. Usual in a concentrated morning sample; context matters. |
| Good | 5 – 8 | Within range (urine pH 5–8). |
| Worth improving | 8 and above | Alkaline urine. Possible infection or diet; context matters. |
Why it matters
ECLM: depends on diet/metabolism; extremes require context (stones/infection).
If it’s low
Acidic (low pH) urine accompanies a diet rich in meat, fasting or certain metabolic disorders; prone to other types of stones (uric acid).
If it’s high
Alkaline (high pH) urine can accompany certain urinary infections or a diet rich in vegetables; it is prone to certain types of stones.
What to do
pH on its own rarely requires action. With recurrent stones a doctor takes it into account in dietary advice.
