Background and Aim: We attempted to estimate the Diagnostic Performance of 2D-Shear wave elastography(2D-SWE) Transient elastography (TE) in predicting esophageal varices patients with compensated cirrhosis. It was then compared each other non-invasive modalities estimation liver stiffness. Methods: 108 cirrhosis underwent B-mode ultrasound, 2D-SWE, TE endoscopy. The diagnostic performance thes...

BACKGROUND HIV infection is a concern in the army troupes because of the risk behaviour of the military population. In order to allow regular access to CD4+ T cell enumeration of military personnel as well as their dependents and civilians living with HIV, the Senegalese Army AIDS program is implementing PIMATM Alere technology in urban and semi-urban military medical centres. Validation such d...

The use of a mouthpiece to measure ventilatory flow with a pneumotachograph (PNT) introduces a major perturbation to breathing ("instrumental/observer effect") and suffices to modify the respiratory behavior. Structured light plethysmography (SLP) is a non-contact method of assessment of breathing pattern during tidal breathing. Firstly, we validated the SLP measurements by comparing timing com...

OBJECTIVES To evaluate the Bio-Rad D-100®, an HPLC analyzer for glycated hemoglobin (HbA1c) determination, and to compare its performance with the Menarini HA-8180V® and Sysmex G8®. METHODS Method comparison was performed according to Clinical and Laboratory Standards Institute (CLSI) EP9-A2 guidelines. We selected 100 samples from the routine laboratory workload and analyzed them in duplicat...

OBJECTIVES To compare intraocular pressure (IOP) measurements made by Goldmann applanation tonometry (GAT) and dynamic contour tonometry (DCT). METHODS IOPs were measured by GAT and DCT in 63 eyes of 63 healthy subjects. A comparison was made by intraclass correlation coefficient. Passing-Bablok plot was constructed to establish the existence of systematic and/or proportional biases. Multivar...

Methods: Thirteen analytes were measured using serum from dogs and cats. Observed total error (TEo) was calculated based on coefficient of variation (CV) and bias. TEo was compared with allowable total error (TEa). Canine and feline samples were collected and measured in five small clinical sites and one reference site. Passing-Bablok regression and Bland-Altman analysis were used to compare PT...

Dentin permeability was measured alternatively with two methods: a 10-microl capillary method with visual evaluation (PC) and a motorized automatic measuring device (Flodec, FD), both interposed in a simulated perfusion system. Eight human third molar coronal fragments were connected to systems, and their permeability to distilled water measured at 0, 5, 10, 15, 20, 25, and 29 cm H(2)O pressure...

Method comparison is commonly performed by laboratory specialists to assess the comparability of two methods. The quality of method comparison study determines the quality of the results and validity of the conclusions. The key to the successful method comparison is therefore a well-designed and carefully planned experiment. The question to be answered by the method comparison is whether two me...

INTRODUCTION Sample type recommended by the manufacturer for the digoxin Abbott assay is either serum collected in glass tubes or plasma (sodium heparin, lithium heparin, citrate, EDTA or oxalate as anticoagulant) collected in plastic tubes. In our hospital samples are collected in plastic tubes. Our hypothesis was that the serum sample collected in plastic serum tube can be used interchangeabl...
