The preanalytical phase, encompassing at large all those activities necessary to obtain a suitable biological specimen, is an essential part of the total testing process [1]. Several lines of evidence attest that uncertainties, poorly standardized and even misleading preanalytical procedures produce the vast majority of problems in diagnostic testing, wherein up to 60%–70% of laboratory errors ...

INTRODUCTION The educational program for health care personnel is important for reducing preanalytical errors and improving quality of laboratory test results. The aim of our study was to assess the level of knowledge on preanalytical phase in population of biomedicine students through a cross-sectional survey. MATERIALS AND METHODS A survey was sent to students on penultimate and final year ...

Remarkable technical advances have permitted analytical measurement of thyrotropin (TSH) and estimates of free thyroxine (FT4) with precision, accuracy, and favorable economics. Combined with an increased appreciation of the key insights into the pituitary-thyroid relation, preanalytical considerations infrequently introduce confounding variables. In reviewing thyroid data, preanalytical consid...

The cobas® Liat® Influenza A/B and respiratory syncytial virus assay was tested on nasopharyngeal aspirates. resolution of invalid samples performed using a preanalytical step. can be used aspirates with processing step, slightly diminished performances in detecting but not for influenza.

BACKGROUND In view of increasing attention focused on patient safety and the need to reduce laboratory errors, it is important that clinical laboratories collect statistics on error occurrence rates over the whole testing cycle, including pre-, intra-, and postanalytical phases. METHODS The present study was conducted in 2006 according to the design we previously used in 1996 to monitor the e...

Background: The complexity of the preanalytical (PA) phase has precluded standardisation of PA processes, despite its impact on sample quality, laboratory effi ciency, or patient & healthcare worker safety. The BD Laboratory Consulting Services™ Preanalytical Review audits PA procedures and practices in hospitals in diff erent countries. Processes were assessed from storage of blood collection ...

Point-of-care testing sites continue to increase in number due to the availability of easy-to-use devices that make it possible to provide test results very quickly relative to the central laboratory services. There is, however, mixed review regarding the accuracy and reliability of POCT results for patient care. It is indicated that most of the test-result-quality concerns are due to complianc...
