Micro-organisms like Staphylococcus saprophyticus use up all your you to definitely chemical, which makes the fresh new nitrite test much less beneficial. Dipstick analysis for leukocyte esterase (brand new chemical created by neutrophils) try indirect and is the most affordable check it out finds pyuria that have an allergic reaction out of 72–97% and you may an effective specificity off 41–86%, as the bacteria aside from uropathogens also can develop leukocyte esterase.30
