A urinalysis (UA) is a set of tests that detect cells and substances (e.g. crystals, casts) in the urine done as part of a health exam or to help detect a urinary tract infection, kidney disorder or other condition.
You may have an infection. 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. A simple dipstick test as part of a urinalysis can detect the presence of this enzyme.
