Hi, welcome to the ehealth forum and I am glad to help you.
You want to know about ua leuk est.
UA stands for urinalysis and leuk est stands for leukocyte esterase.Leukocyte esterase is a urine test to look for white blood cells and other signs associated with infection.
Leukocyte esterase is a screening test used to detect a substance that suggests there are white blood cells in the urine, which may mean you have a urinary tract infection.
This test is part of the routine urine dipstick test. If this test is positive, the urine should be examined under a microscope for white blood cells and other abnormalities associated with infection.
Hope this helps. Take care.
