During review of a urinalysis, which value would be considered abnormal?

• A. Specific gravity 1.03
• B. Urine pH 3.0
• C. Absence of protein
• D. Absence of glucose

Answer: (C)

Interpreting a urinalysis hinges on normal reference ranges. Normal urine pH is typically around 4.5 to 8.0, and normal urine should not have protein or glucose detectable; specific gravity around 1.005–1.030 is common depending on hydration.

A urine pH of 3.0 is far below the normal range, indicating unusually acidic urine. That makes it the abnormal finding. The other values listed—specific gravity near 1.03, absence of protein, and absence of glucose—are all consistent with normal urinalysis results (presence of protein or glucose would be the abnormal findings in those contexts).
