Urine pH

The pH test measures how acidic or basic the urine is. High acidity can point to acidosis, gout, infection, high protein, infection and other problems while very basic urine can indicate infection, low stomach acid and ingestion of alkalizes.

Urine pH changes throughout the day which is why a first morning urine void is important when assessing pH levels. The first morning urine should be more acidic and the urine can get more alkaline throughout the day. Acidic urine in the morning shows the body is able to concentrate urine overnight. As the day progresses the pancreas secretes bicarbonate during pancreatic activity to slowly alkalize the urine towards the later part of the day. Finding the balance of acid and alkalinity of the urine is important at assessing digestive function and metabolic problems in the body.
