What is the normal hemoglobin level on dipstick in urine?

• A. Positive on dipstick
• B. Negative on dipstick
• C. Trace
• D. High

Answer: (B)

Normal urine should not have detectable hemoglobin on a dipstick. The dipstick detects heme via a peroxidase-like reaction, so if there is no blood or heme present, the result stays negative. A positive result would indicate the presence of blood or myoglobin, while a trace could come from contamination or very small amounts that aren’t typical of a normal urine sample. A high reading points to more substantial blood or hemoglobin in the urine. So, the best interpretation for a normal finding is negative on the dipstick.
