Dipstick studies getting leukocyte esterase (the brand new enzyme produced by neutrophils) try secondary that is the lowest priced test that detects pyuria with an allergy from 72–97% and good specificity away from 41–86%, since organisms other than uropathogens may also write leukocyte esterase.30
