Pre Analytical Variables In Coagulation Testing Pdf Coagulation Many preanalytical variables may affect the results of routine coagulation assays. while advances in laboratory instrumentation have partially addressed the laboratory's ability to recognize some of these variables, there remains an increased reliance on laboratory personnel to recognize the three p …. 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 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 events associated with sample collection and processing, as well as post analytical events related to the reporting and interpretation of test results. 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. 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. The frequency of pre analytical errors has been estimated to be as high as 5% of all blood collections for coagulation testing, with notable variations among medical disciplines.1 spurious hemolysis can be prevalent in emergency departments, while clotted samples can be common in neonatal and pediatric settings.

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. failure to recognize or address these pre analytical variables may lead to inaccurate or misleading test values, resulting in patient mismanagement. Abstract there are many preanalytical variables (pav) that are known to affect coagulation testing. the more commonly acknowledged pav addressed by the clinical laboratory tend to start with their influence on blood collection, but realistically coagulation pav starts with the patient, where the laboratory has less influence or control.
