BACKGROUND Efficient laboratory service is the cornerstone of modern health care systems. Scientific innovations have contributed to substantial improvements in the field of laboratory science, but errors still prevail. These errors are classified as preanalytical, analytical and postanalytical, depending upon the time of presentation. METHODS The data for 67,438 routine venous blood specimen...

INTRODUCTION Studies about vitamin D [25(OH)D] stability in plasma are limited and preanalytical variables such as tube type may affect results. We aimed to evaluate effect of storage conditions, sample type and some preanalytical variables on vitamin D concentration. MATERIALS AND METHODS Blood samples from 15 healthy subjects were centrifuged at different temperatures and stored under diffe...

The recent emergence of methods for rapidly profiling large numbers of protein markers by use of mass spectrometry (MS) has raised hopes for the rapid identification of novel cancer biomarkers (1 ). In particular, MSbased assays using surface-enhanced laser desorption/ ionization (SELDI) have been used to compare serum proteomic patterns from healthy and diseased individuals in hopes of finding...

Point-of-care testing (POCT) represents one of the fastest growing segments of the diagnostics market. Although major advances have been made in the instrumentation and methods used for POCT, further development and enhancements appear to be necessary to meet the challenges presented by the difficult testing environments in which these devices are used. In addition, the varied experience and tr...

Abstract Background and aims We assessed the possibility to rule out negative urine cultures by counting with UriSed 3 PRO (77 Elektronika, Hungary) at Helsinki Uusimaa Hospital District. Materials methods Bacteria of automated microscope was verified reference phase contrast microscopy against growth in culture. After acceptance into routine, results bacteria leukocyte from 56 426 specimens ei...

The clinical laboratories worldwide have faced numerous obstacles due to the COVID-19 pandemic. In midst of this outbreak, mistakes that occur during preanalytical phase sample collection, transportation, and processing can result in unfavorable outcomes. Therefore, aim investigation was ascertain contrast rate at which blood specimens are rejected by a laboratory analyze compare types errors p...
