*4.1.12 Leucocyte esterase reagent strip*

Several studies have shown the usefulness in the use of leucocyte esterase reagent strip in diagnosing spontaneous bacteria peritonitis and in urinary analysis with sensitivity ranging from 80 to 93% and specificity 93–98% [45]. The negative predictive value is markedly high from 97 to 99%, a good measure for an ideal tool to rule out SBP [45]. Recent development has discovered an ascite-specific reagent strip with a cut-off value of 250 cells/mm3 which would further enhance diagnostic accuracy [46].
