Pre Analytical Variables In Coagulation Testing Pdf Coagulation Page 5 of 6 f [mls12ba] module 4 pre analytical variables and coagulometry 2. thrombin generation assays (tga) measure the phased kinetics of thrombin generation from initiation and peak generation through downregulation and inactivation whole measurement of the process: from generation of thrombin until the clot dissolves. Variables during sample collection during the pre analytical phase, in case of haemostasis testing for patients with a positive history of haemorrhagic diathesis, certain steps regarding the preparation of patients and the execution of sampling (specimen collection, transportation, sample preparation and storage) are of special importance.
Pre Analytical Variables In Coagulation Testing 01 Pdf 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 purpose of this article is to identify the preanalytical variables associated with coagulation related testing and provide laboratory practice recommendations in an effort to improve the quality of coagulation testing and accuracy of result reporting. many preanalyticalvariables mayaffect the resultsof routine coagulation assays. Pre analytical variables associated with patients, specimen collection, specimen transportation, and specimen processing and storage can cause significant differences in the values obtained from routine and specialized coagulation testing. All coagulation tests critically depend on the quality of the plasma specimens obtained. pre analytical variability is a common source of errors in coagulation testing, as clotting assays are.

Abstract the use of modern laboratory instrumentation with high levels of test reliability and appropriate quality assurance measures will lead to very few analytical errors within hemostasis testing. nevertheless, incorrect or inappropriate test results are still reported, often due to events outside the control of the laboratories performing the tests. this is due primarily to pre analytical. Many misleading results in blood coagulation arise not from errors in testing but from carelessness in the pre analytical phase. pre analytical factors influencing the reliability of laboratory testing are commonplace. control is critical, since this has a direct influence on the quality of results and their clinical reliability.
