Why is the Test Performed?

Leukocyte esterase is a screening test used to detect an enzyme that suggests the presence of leukocytes (white blood cells), and probably a urinary tract infection. This test is part of the routine dipstick test. If this test is positive, the urine should be examined microscopically for the presence of white blood cells and other abnormalities associated with infection.
