What is the normal pH value range for urine?

The normal pH value range for urine typically falls between 4.5 to 8.0. This range reflects the body's ability to regulate urine pH through various metabolic processes and factors such as diet, hydration, and health status.

Urine can be more acidic in response to high-protein diets or metabolic conditions, while a more alkaline pH may occur in vegetarians or due to certain medications. The range of 4.5 to 8.0 encompasses these variations, making it the most accurate representation of normal urine pH levels.

Other ranges provided do not appropriately capture the typical variations found in urine. For example, a narrower range of 5.5-7.0 would not account for instances where urine is more acidic or alkaline. Therefore, the broader range is essential for recognizing the diversity of urine pH influenced by dietary and physiological changes.
