What is the normal pH range for urine?

• A. 4-6
• B. 5-9
• C. 7-12
• D. 3-4

Answer: (B)

Urine pH shows how acidic or alkaline the urine is, and the kidneys can adjust this balance based on diet and overall acid-base status. In most clinical references, the normal urine pH falls roughly between 5 and 9. This range covers the wide variability seen with different meals and hydration. Values well below 5 are very acidic, while values near or above 9 are very alkaline; both extremes are uncommon in healthy individuals and may prompt investigation for infection, stone risk, or metabolic changes. The selected range is the best fit for what’s considered normal, while the other ranges either exclude normal samples or include values that are not typically seen in healthy urine.
