OBJECTIVE The performance of automated flow cytometric urinalysis is not well described in pediatric urinary tract infection. We sought to determine the diagnostic performance of automated cell counts and emergency department point-of-care (POC) dipstick urinalyses in the evaluation of young febrile children. METHODS We prospectively identified a convenience sample of febrile pediatric emerge...

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...

A positive dipstick urinalysis (i.e., leukocyte esterase test and/or nitrite test) did not reliably detect significant bacteriuria in 479 ambulatory women with suspected uncomplicated urinary tract infection; 18.9% of the urine samples that demonstrated significant bacteriuria would have been rejected by the laboratory based on a negative urinalysis screen.

UF-100 flow cytometer and urine strip results were cross-interpreted to predict culture outcomes. The best negative predictive value was obtained with bacteria at > or =1,000/microl, white blood cells at > or =20/microl, or leukocyte esterase positivity. Nine of 24 false negatives were clinically significant. Thus, UF-100 and urine strip results do not accurately predict the outcome of cultures.

Background: The most common infections among all age groups are the urinary tract infections, mostly among pregnant women. Aim and Objective: To screen pregnant women for ASB with wet mount, reagent strip test such as UROCOLOR 10, by which both nitrite and leukocyte esterase was detected. Materials and methods: This was a multi-centric study conducted at Government Hospital Nizamabad and CKM ho...

BACKGROUND Spontaneous bacterial peritonitis (SBP) is a common and important clinical problem and is life-threatening in decompensated liver disease. Ascites fluid test by leukocyte esterase test strip has been recently proposed as an effective and rapid method to diagnose SBP in patients with cirrhosis. OBJECTIVES This study aimed to evaluate sensitivity and specificity of leukocyte esterase...
