Urinary tract infection is one of the most commonly encountered genitourinary disease in pediatric practice. Diagnosis and management of urinary tract infection is a matter of concern in hospital settings and at community level. This study tries to establish the relevance of urine dipstick analysis and microscopy in detecting UTI. In this study a control group and a study group of equal number ...

Periprosthetic infection (PJI) is one of the most frequent and devastating complications total hip arthroplasty (THA). Early accurate diagnosis PJI allows timely initiation treatment. Various diagnostic tools algorithms for are described. The available serum (ESR, CRP, D-dimer, etc.) synovial (alpha-defensin, leukocyte esterase, D-lactate) biomarkers listed, as well their combinations purpose v...

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...

Bacteriuria is the leading indicator of Urinary Tract Infection (UTI), which detected through urine culture examination. Significant bacteriuria indicates growth microorganisms as much ≥ 100,000 cfu/ml in culture. There are drawbacks to this examination that requires a screening test with short time and lower cost. This study aimed determine differences results nitrite leukocyte esterase using ...

In order to compare the performance of leukocyte esterase and nitrite urine dipstick tests with enhanced urinalysis (uncentrifuged urine white blood cell count/mm(3) plus Gram stain) in detecting asymptomatic bacteriuria in obstetric patients, clean-catch midstream urine specimens were collected from 250 consecutive asymptomatic pregnant women. Ten of the women (4.0%) showed urine culture resul...

BACKGROUND Few studies have evaluated dipstick urinalysis for elderly and practically none present confidence intervals. Furthermore, most previous studies combine all bacteria species in a "positive culture". Thus, their evaluation may be inappropriate due to Yule-Simpson's paradox. The aim of this study was to evaluate diagnostic accuracy of dipstick urinalysis for the elderly in nursing home...

BACKGROUND Urine test strip results are generally reported in categories (i.e., ordinal scaled), but automated strip readers are now available that can report quantitative data. We investigated the possible use of these meters to complement flow cytometry of urine and compared reflectance readings with quantitative determinations of urinary glucose and microalbumin. METHODS We compared URISYS...

Leukocyte Esterase and Hemoglobin Test Strips To the Editor: During a recent evaluation of a new glucose test (1), we also evaluated the effect of ascorbic acid on results for 1

Evaluations of screening tests for bacteriuria have traditionally compared the test results with those of quantitative urine cultures. However, many patients with symptomatic urinary tract infections can have less than 10(5) CFU/ml in their urine. Therefore, the results of urine culture and three screening tests (Bac-T-Screen, Chemstrip LN [which tests for leukocyte esterase and nitrate reducta...
