In predicting pediatric kidney depth, we are especially interested in that the errors of most estimates are within a narrow range. Therefore, this study was intended to use the proportion of estimates within a range of -5 to 5 mm (P5 mm) to evaluate the formulas and tried to regress a kidney depth formula for children. The enrolled children aged from 1 to 19 years were randomly sampled into gro...

OBJECTIVES The aim of our study was to evaluate, in acute ischemic stroke patients, the diagnostic accuracy of the MRI susceptibility vessel sign (SVS) against catheter angiography (DSA) for the detection of the clot and its value in predicting clot location and length. MATERIALS AND METHODS We identified consecutive patients (2006-2012) admitted to our center, where 1.5 T MRI is systematical...

SIGNIFICANCE This study evaluates the reliability and validity of an automatic method external internal limbal points identification from anterior segment optical coherence tomography (OCT) images in comparison with manual delineation. PURPOSE The purpose this work was to evaluate repeatability precision a previously proposed compare them delineation by experienced clinicians terms limbus diame...

BACKGROUND Comparing four fully automated 25-OH-D immunoassays to a commercially available liquid chromatography-tandem mass spectrometry (LC-MS/MS) method with human serum samples from Finnish population. METHODS 400 samples were analyzed with the Liaison Total Vitamin D, the IDS-iSYS 25-Hydroxy Vitamin D, the ARCHITECT 25-OH Vitamin D, the ADVIA Centaur Vitamin D Total, and a commercially a...

In a previous work, an automated alcohol dehydrogenase method for the quantification of ethanol in whole blood (blood) specimens was presented. In the present work the application of the method to urine specimens has been investigated. Also, method robustness to routine analysis of urine and blood specimens during a period of eight months is shown. The limits of detection and quantification for...

Ves-Matic Cube 200 is fully automated analyzer that performs erythrocyte sedimentation rate (ESR) measurement using the standard ethylenediaminetetraacetic acid blood sample tube, thus markedly reducing the analytical time and avoiding the need for an extra blood sample. The aim of this study was to assess the automatic Ves-Matic Cube 200 system for the measurement of ESR in comparison with the...

Abstract Objectives We evaluated analytical performance, functionality, reliability, and comparability of cobas ® pure integrated solutions (Roche Diagnostics) under routine-like conditions. Methods The study was conducted in Europe Asia (five sites). Seventy-six applications covering ion selective electrolytes (ISE), clinical chemistry (CC), immunochemistry (IC) analytes were assessed using El...

BACKGROUND For TDM of mycophenolate acid (MPA), the Roche Total Mycophenolic Acid® assay based on the inhibition of recombinant inosine monophosphate dehydrogenase (IMPDH) has been shown to be a simple and reliable alternative to chromatographic methods. We have adapted this assay on the ABX Pentra 400 analyzer (HORIBA). OBJECTIVE To investigate the analytical performances of the Roche Total ...

OBJECTIVES Blood lactate measurements are common as a marker of skeletal muscle metabolism in sport medicine. Due to the close equilibrium between the extracellular and intramyocellular space, plasma lactate is a more accurate estimate of muscle lactate. However, whole blood-based lactate measurements are more convenient in field use. The purpose of this investigation was therefore (1) to estab...

OBJECTIVES To evaluate performance characteristics of the newly available handheld combined glucose and ketone meter for beta-hydroxybutyrate measurement. DESIGN Laboratory method evaluation. MAIN OUTCOME MEASURES Accuracy of beta-hydroxybutyrate measurement and effect of acetoacetate interference at clinically important beta-hydroxybutyrate levels. RESULTS Deming regression analysis of b...
