pH
Description
- 4.5 to 8.0
Clinical significance
- Normal urine pH is slightly acidic, with usual values of 6.0 to 7.5, but the normal range is 4.5 to 8
- In persons with hyperuricosuria, acidic urine can contribute to the formation of stones of uric acid in the kidneys, ureters, or bladder
- Kidneys play an important role in maintaining the acid-base balance of the body. Therefore any condition that produces acids or bases such as acidosis or alkalosis or ingestion of acidic or basic foods can directly affect urine pH
- Some substances dissolved in urine precipitate out to form crystals when the urine is acidic, other when the urine is basic. By modifying urine pH through diet or medications, the formation of these crystals can be reduced or eliminated
