Which statement best reflects what the leukocyte test pad on a urine reagent strip measures when read at the appropriate time?

Explanation:
Leukocyte esterase in urine is what the pad detects. The pad contains a substrate that leukocyte esterase cleaves, producing a color change when read at the recommended time. A positive result indicates the presence of white blood cells in the urine, which commonly signals inflammation or infection of the urinary tract (pyuria). This is distinct from the other pads: the glucose pad measures glucose, the blood pad detects occult blood, and the nitrite pad detects bacterial conversion of nitrates to nitrites.
