The validity of the leukocyte esterase reagent test strip in detecting significant leukocyturia.
This prospective trial demonstrated that the best possible definition for a positive leukocyte esterase test (Chemstrip 9) is + or ++. With use of this definition, the sensitivity in detecting significant leukocyturia is 83% and the specificity is 70%. The use of this test strip could reduce screening costs in registering obstetric patients.
