Leukocyte Esterase is used in a urine test for presence of white blood cells abnormalities associated with infection. Urine tests reveal the presence of granulocyte esterases. The esterases cleave a derivatized pyrazole amino acid ester to liberate derivatized hydroxy pyrazole. This pyrazole then reacts with a diazonium salt to produce a purple color. White blood cells in the urine usually indicate a urinary tract infection. Human leukocytes esterase test detects human esterase, an enzyme released by white blood cells. Human White blood cells are produced in the bone marrow and help to defend the body against infectious disease and foreign materials as part of the immune system. Human Leukocytosis is very common in acutely ill patients. It occurs in response to a wide variety of conditions, including viral, bacterial, fungal, or parasitic infection, cancer, and exposure to certain medications or chemicals. Human leukocytes are used in routine dipstick tests and urine controls. If this Human leukocyte test is positive, the urine should be examined microscopically for the presence of white blood cells and other abnormalities associated with infection.
