Normal urinalysis nitrite level is:

Normal urinalysis nitrite level is:

• A. Negative
• B. Trace
• C. Not detected
• D. Positive

Answer: (A)

Nitrite in urine is produced when certain bacteria reduce nitrates that are normally present in urine. In a healthy person, there aren’t bacteria in the urinary tract producing nitrite, and there isn’t always enough time in the bladder for any nitrate-to-nitrite conversion to occur. Because of that, nitrite is not detected, so the normal urinalysis nitrite result is negative. A positive result would point to a nitrate-reducing bacterial infection, whereas trace or not detected imply little to no detectable nitrite—negative remains the typical finding in a normal sample. Remember, some UTIs caused by organisms that don’t reduce nitrate can still occur even if nitrite is not detected.
