STUDY OBJECTIVE In the present study, we evaluated the leukocyte esterase (LE) area of a reagent strip designed for urinalysis for the semiquantitative measurement of the percentage of polymorphonuclear neutrophils (PMNs) in BAL fluid. DESIGN Prospective. The relative PMN counts (obtained by conventional microscopy and expressed as a percentage of a 500 cell count) of consecutive BAL fluid sa...

We examined 288 urine samples, using test strips, sediment microscopy, and culture. The ability of the leukocyte esterase and nitrite test strips to detect or exclude urinary tract infection, as defined by a positive culture, was evaluated by probability analysis. We found that the diagnostic efficiency of the esterase-nitrite combination was similar to that of sediment microscopy. Moreover, on...

OBJECTIVE To determine the sensitivity, specificity, Positive Predictive Value (PPV) and Negative Predictive Value (NPV) of Urine Nitrite (NIT) and Leukocyte Esterase (LE) test compared with urine culture for diagnosis of UTI. STUDY DESIGN Validation study. PLACE AND DURATION OF STUDY Department of Microbiology, Army Medical College, Rawalpindi, from January 2013 to December 2013. METHODO...

The examination of. urine specimens constitutes a major portion of the work of a clinical microbiology laboratory. Although the prevalence of urinary tract infection varies for different patient populations, most urine specimens are culture negative. In this laboratory only 12% of paediatric urines show evidence of urinary tract infection. The availability of a rapid reliable screening test for...

In the present study, the effect of intrauterine infusion of Zataria multiflora extract on the clinical endometritis was investigated. Vaginal examination, transrectal palpation and ultrasonography were used to inspect the genital tract at 30-40 days in milk and two weeks later the same approach was applied. Cows with clinical endometritis were randomly divided into three treatment gro...

BACKGROUND Periprosthetic joint infection (PJI) is a complication of total joint arthroplasty (TJA). The leukocyte esterase (LE) strip test and histology are diagnostic methods for PJI. The aims of this study were to determine the sensitivity and specificity of the LE strip test and to compare it with histology in the diagnosis of PJI. MATERIAL AND METHODS Between January and December 2015, 93 ...

deficiency. It is not applicable to newborn or mass screening with use of ifiterpaper specimens, but is satisfactory for liquid urine screening. In one variant of sulfite oxidase deficiency, due to a defect of its molybdate cofactor metabolism, the concentration of uric acid in serum is decreased. Thus, an unexplained low serum uric acid, especially in a young patient with neurologic abnormalit...

Esterolytic activity of three enzymic cholesterol reagents was evaluated with use of human serum-based reference materials. Primary cholesterol standards were used to calibrate the enzymic methods, and incomplete cholesteryl ester hydrolysis was measured as the bias between the enzymic cholesterol values and corresponding reference values. The average biases observed with eight reference specim...
