Pre Analytical Variables Of Lab Testing Summary preanalytical phase is an important component of total laboratory quality. current efforts towards the standardization of preanalytical phase has increased the awareness of the effect of this critical component on laboratory results. Summary pre analytical variables play a crucial role in influencing the accuracy of test results in medical lab and phlebotomy practice in the united states. factors such as specimen collection, handling, transportation, and patient preparation can impact the reliability of laboratory tests.
Pre Analytical Variables Of Lab Testing Introduction a large number of variables can potentially affect the results of a laboratory test and these can be divided into: pre analytical variables analytical variables post analytical variables there is increasing evidence that an awareness of the significance of the pre analytical variables that can potentially affect a lab test, will ensure the reliability of the final result. The laboratory total testing process begins with the preanalytical phase and concludes with the postanalytical phase. due to improvements in analytical techniques and effective quality programs, most errors now occur in the pre and postanalytical phases, areas that laboratory professionals sometimes perceive as being ‘out of our control’. Mples different preanalytical variables were categorized separately. results and conclusion: out of 33303 samples analysed over a period of 6 months pre analytical errors were seen in 1.38% (n=461) samples, with the commonest er keywords: preanalytical variables, pre analytical errors, hospital laboratory services, quality assurance. Most errors affecting laboratory test results occur in the pre analytical phase, primarily because of the difficulty in achieving standarized procedures for sample collection.

Most errors affecting laboratory test results occur in the pre analytical phase, primarily because of the difficulty in achieving standarized procedures for sample collection. Pre analytical variables account for 32% 75% of laboratory errors pre analytical variables refers to any and all procedures that occur during sample collection, prior to sample analysis. this involves patient identification, physical sample collection, sample transportation to the testing site and sample preparation. The awareness towards recognition by pre analytical errors and introduction of strategies to achieve total laboratory quality is finally within our reach to improve the biochemistry results and leading to good patient care. key words: pre analytical, variables, accuracy.
