It was shown in the preceding paper that incubation of the rabbit polymorphonuclearleukocyteswith phosphonate esters leads to an irreversible inhibition of the ability of the leukocyte to respond to the chemotactic factor. This "cell-dependent inhibition" was attributed to the inactivation by the phosphonates of an esterase existing in or on the leukocyte in an already activated state. As shown...

For 422 male patients with symptoms indicative of a urinary tract infection, nitrite and leukocyte esterase activity dipstick test results were compared with results of culture of urine samples. The positive predictive value of a positive nitrite test result was 96%. Addition of results of the leukocyte esterase test did not improve the diagnostic accuracy of the nitrite test.

We evaluated 230 body fluid samples, of which 131 were peritoneal effluents and 99 were other body fluids. Of these, 63 dialysates were culture positive, and 54 (85.7%) of these 63 were leukocyte esterase positive. Of 99 other body fluids, 8 were both culture positive and leukocyte esterase positive.

background: the study was conducted to estimate and compare the validity and performance of two screening methods for uri­nary schistosomiasis: the interview - reporting blood in urine- and detecting microhematuria by reagent strip. methods:  in year 2003, 515 schoolchildren from five schools in abyan and taiz governorates in yemen, were in-terviewed by healtworker for hematuria, and then urine...

For the rapid and simple diagnosis of schistosomiasis, a reagent strip assay for detection of circulating cathodic antigen (CCA) in urine was developed. The test was based on a previously developed sandwich enzyme-linked immunosorbent assay (ELISA) using a combination of two anti-CCA monoclonal antibodies. For the reagent strip assay, as the capture matrix, monoclonal antibody was coated onto a...

The results of a study of a screening test for urinary tract infection (UTI) in infants under 18 months is reported. Two hundred and forty three urine specimens were tested in the laboratory using AMES Multistix 8SG reagent strips read by photometer. The strips included three potential markers for urinary tract infection: leucocyte esterase, nitrite, and protein. The predictive value of a posit...
