Pre Analytical Variables Affecting Laboratory Results Ppt This document discusses the significant role of pre analytical variables in laboratory testing, which account for up to 75% of laboratory associated errors. it classifies these variables into controllable factors (such as patient preparation and sampling techniques) and non controllable factors (such as age and medical conditions). understanding these influences is crucial for improving the. The result of this issignificant gains in analytical performance in terms of precision, accuracy, sensitivity and specificity complementing these gains has been a steady improvement in quality control and quality assurance programs effects of pre analytical variables on the quality of laboratory testing.
Pre Analytical Variables Affecting Laboratory Results Ppt Recognition of pre analytical variables causing changes in laboratory results • in opd, blood was collected with the application of tourniquet and fist clenching • in the ward, blood was collected through an in dwelling catheter • cause of pseudohyperkalemia was repeated fist clenching during tourniquet application intended to make the.

Introduction laboratory analytes subject to several sources of variation biological variation (within and between person variation) pre analytical variation (patient status, specimen collection and transport, specimen processing and delivery to the instrument) analytical variation (bias and imprecision) postanalytical variation (reporting of results) also prepre and postpost. The document discusses preanalytical variables in medical testing that can affect the accuracy of test results, categorized into controllable and uncontrollable factors. controllable variables include test collection, patient preparation, and lifestyle factors like diet and exercise, while uncontrollable variables encompass biological influences such as age, sex, race, and environmental.
