What is the lowest recorded urine pH indicated?

The lowest recorded urine pH is typically around 4 pH. Urine pH can vary widely based on diet, metabolic state, and hydration levels. A pH of 4 indicates a highly acidic urine, which can occur in conditions like acidosis, dehydration, or a diet high in protein.

Urine pH values lower than 4 are rare and may occur under specific pathological conditions, but in general practice and normal physiological conditions, 4 is often accepted as the lowest typical value encountered. Other values, such as 6, 5, or even 7, reflect more neutral or slightly acidic states, which are commonly found in urine but do not represent the extreme acidity seen at a pH of 4. Thus, identifying 4 pH as the lowest recorded urine pH level aligns with established clinical knowledge regarding urine acidity.
