Urine pH, also called urine pH, is a relatively important indicator in urine routine, reflecting a performance of human kidney function. The kidney will have a certain role in regulating the acid-base balance of the body, and the body can excrete a large amount of acidic or alkaline substances through urine, which is used to maintain the acid-base balance. The pH of normal urine is about 4.5-7.9. If you consume a lot of protein, it may produce acidic urine, and if you consume a lot of vegetables or fresh fruits, the urine will often be alkaline. So as long as the pH of urine is between 4.5 and 7.9, it can be considered normal.
