BACKGROUND Total joint arthroplasty (TJA) has been one of the most rewarding interventions for treating patients suffering from joint disorders. However, periprosthetic joint infection (PJI) is a serious complication that frequently accompanies TJA. Our study aimed to investigate the application of the leukocyte esterase (LE) strip in the diagnosis of PJI. MATERIAL AND METHODS From October 2014...

OBJECTIVE To study the accuracy and clinical application of the dipstick leukocyte esterase test in the detection of pyuria in young febrile children suspected to have urinary tract infection. DESIGN Prospective study. SETTING Regional hospital, Hong Kong. PATIENTS Urine samples were taken from 215 children younger than 2 years who were suspected to have urinary tract infection (fever wit...

Abstract Background The purpose of the study is to evaluate performance and agreement rapid point-of-care (POCT) urine dipstick testing in emergency department (ED) a laboratory-automated platform. Methods A total 30 specimens were collected from at our hospital simultaneously tested for urinalysis (UA) on POCT Siemens Clinitek Status+ analyzer using Multistix 10SG strip. In laboratory, we perf...

Background: Despite improvement in sterilization techniques, peri-prosthetic joint infection (PJI) is the most fearsome complication after hip and knee arthroplasties. Various strategies have been devised from time to diagnose treat PJI. Recently, Leukocyte esterase alpha-defensin are identified as markers of active synovial fluid. Therefore, kits designed detect these two during surgery. If fo...

Procedure and Notes • Use only well mixed, non-centrifuged urine, which should not be older than 4 hours. First morning urine is recommended. Protect the samples from light. • If the samples cannot be tested immediately, they should be stored at 2...4°C and brought to room temperature (15...25°C) before testing. • Collect specimen in clean, well rinsed containers, free of detergents. Do not add...

This paper presents a rotary device designed for facile delivery of multiple reagents to a paper strip for multistep assays. Its purpose is to allow users to easily perform multistep assays and achieve sensitive detection. While the test strip remains stationary, rotating the top piece of the device aligns the reagent and absorbent pads to each end of the paper strip and initiates fluid flow. F...

The effect of changes in packed cell volume was studied in two commonly used reagent strip methods (Dextrostix and Reflotest) of measuring blood glucose and in a filter paper blood spot method. It was found that the results with both the reagent strip methods were greatly haematocrit-dependent. Attention is drawn to the possibility of false diagnoses of hypoglycaemia in haemoconcentrated patien...

PURPOSE This study was to determine if dip stick assays of children's saliva for leukocyte esterase or protein (Serim Research Corporation, Elkhart, Ind) reflect the presence or severity of gingival or periodontal diseases in children. METHODS The study included 13 children with periodontitis [study group] and a control group of 17 children without periodontitis. The saliva leukocyte esterase...
