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. 13 effects of pre analytical variables on the quality of laboratory testing patient identification it is important to identify a patient accurately so that blood is collected from the correct person. drawing blood from the wrong person, or labeling the correct patients sample with a different patients label can certainly contribute to. Pre analytical variables the monitoring & control of pre analytical variables is difficult because many of the variables are out side the traditional laboratory area. pre analytical variables requires the coordinated effort of many individuals & hospital departments , each of which must recognize the importance of high quality service. The document outlines the impact of various preanalytical and biological variables on laboratory test results, categorizing them into controllable and non controllable factors such as posture, diet, exercise, age, and underlying diseases. it also emphasizes how individual variations and environmental factors can influence these test results, highlighting the importance of understanding these.

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 test variables and how they can affect test results. it describes the three stages of diagnostic testing as pre analytical, analytical, and post analytical. pre analytical variables, such as errors in patient preparation or sample collection, account for 62% of errors. analytical variables related to testing procedures account for 15% of errors, while post analytical.
