Which analyte is not measured by a standard urine dipstick?

• A. Glucose
• B. BUN
• C. Total protein
• D. Blood

Answer: (B)

Urine dipsticks are designed to screen for substances that appear in urine and reflect kidney function and metabolic status. They include pads that detect glucose, protein, and blood, among other components. Glucose appears in urine when blood glucose is high, protein shows up as proteinuria, and blood indicates present red cells or hemoglobin. BUN (blood urea nitrogen) is a marker measured in the blood to assess renal function and hydration; it is not assessed by a standard urine dipstick. To evaluate BUN, you’d use a blood chemistry test, not the dipstick.
