Normal urinalysis leukocyte esterase level is:

Normal urinalysis leukocyte esterase level is:

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

Answer: (D)

Leukocyte esterase on a urinalysis dipstick reflects white blood cells in the urine. In a healthy person, there are few or no white blood cells, so the test line should not appear—it's negative. A negative result means no significant pyuria and makes infection or inflammation less likely. Positive or even trace results suggest the presence of leukocytes (pyuria) and warrant further clinical evaluation, but the normal finding is negative. Not measured isn’t applicable in standard urinalysis.
