Harmonization encompasses all efforts made in a search for differences in policies and procedures and minimizing these. Since it reduces variability and errors, harmonization certainly leads to the quality improvement in every system. During the 3rd EFLM-BD European Conference on Preanalytical Phase held during 20 – 21 March in Porto (Portugal), representatives of many member societies of Europ...
Blood gas testing is a commonly ordered test in hospital settings, where the results almost always have the potential to dictate an immediate or urgent response. The preanalytical steps in testing, from choosing the correct tests to ensuring the specimen is introduced into the instrument correctly, must be perfectly coordinated to ensure that the patient receives appropriate and timely therapy ...
In the January issue of Jpn J Clin Oncol, Wang et al. (1) found that preoperative carcinoembryonic antigen (CEA) levels are an independent prognostic factor in non-metastatic colorectal cancer patients after curative surgery. As the authors correctly pointed out, the prognostic significance of CEA is controversial in these patients. In order to explain the contradictory results that can be foun...
BACKGROUND Management and traceability of biospecimen preanalytical variations are necessary to provide effective and efficient interconnectivity and interoperability between Biobanks. METHODS Therefore, the International Society for Biological and Environmental Repositories Biospecimen Science Working Group developed a "Standard PREanalytical Code" (SPREC) that identifies the main preanalyti...
BACKGROUND We sought a practical method to calculate preanalytical uncertainties. In clinical chemistry measurements, the combined preanalytical uncertainty is a function of the magnitude and probability distribution of the different uncertainty sources and the number of such sources. METHODS Results from an optimal practice for handling of the blood samples (termed the standard method) were ...
While analytical standards have been developed by established quality control criteria, there has been a paucity in the development of standards for the preanalytical phase. Only recently recommendations have been published regarding the quality of samples including the definition of the optimal sample size, the use of anticoagulants and stabilizers, stability criteria regarding transport and s...
European Federation of Clinical Chemistry and Laboratory Medicine (EFLM) Working group for preanalytical phase (WG-PRE) has recently launched a series of conferences on preanalytical phase. First such meeting was held in Parma (Italy) in the spring of 2011 and the second one took place in Zagreb (Croatia) during 1-2 March 2013. The Zagreb audience had the opportunity to enjoy a focused and chal...
Phlebotomy is one of the most complex medical procedures in the diagnosis, management and treatment of patients in healthcare. Since laboratory test results are the basis for a large proportion (60-80%) of medical decisions, any error in the phlebotomy process could have serious consequences. In order to minimize the possibility of errors, phlebotomy procedures should be standardised, well-docu...
Research of new diagnosis or prognosis biomarkers is a major challenge for the management of patients with complex pathologies like cancer. Clinical proteomics is one of the recent approaches to identify these biomarkers in biological fluids. Over the last five years, many problems related to the variability and the quality control of these analyses have been observed. This was notably related ...
Evaluating the kinetics of cell-free DNA (cfDNA) in the blood of cancer patients could be a strong auxiliary component to the molecular characterization of cfDNA, but its potential clinical significance is obscured by the absence of an analytical consensus. To utilize quantitative cfDNA assessment with confidence, it is crucial that the preanalytical phase is standardized. In a previous publica...
