Which statement is true regarding hemoglobin on the dipstick in a normal urinalysis?

Explanation:
Hemoglobin on the dipstick should be negative in a normal urinalysis. The dipstick detects the heme component of hemoglobin via a peroxidase-like reaction, so if there’s no heme in the urine, there’s no color change. A positive result would indicate the presence of blood in the urine (hematuria) or free hemoglobin/myoglobin, which isn’t expected in a normal sample. Therefore, the true statement is that the dipstick for hemoglobin will be negative.
