A positive finding of the enzyme leukocyte esterase in urinalysis indicates the presence of white blood cells in the urine. This normally suggests inflammation of some sort, often from a urinary tract infection.lthough a urinary tract infection is the most common cause of leukocyte esterase in urinalysis some other and rarer causes for the positive result with a negative microorganism culture do exist. [2] These include:
Leukocytes are white blood cells that protect the body from infections and certain diseases. White blood cells in the urine are detected by measuring the amount of leukocyte esterase in the urine.Esterase is an enzyme that is produced by white blood cells, and it is the identifying factor in detecting leukocytes.eukocytes are white blood cells that protect the body from infections and certain diseases.
