Preanalytical Variables in Hemostasis Testing Webinar

Many pre-analytical variables (PAVs) may affect the results of routine coagulation assays. To improve the precision and accuracy of laboratory testing, it is critical to identify these variables and realize their potential impact. Additionally, advances in laboratory instrumentation have improved the reproducibility and sensitivity of the analytical phase, therefore creating greater dependence on specimen integrity. During this presentation, you will learn about the most important factors that may impact the integrity of a coagulation sample: from blood collection, sample preparation and transportation to specimen related interfering substances and their effect on the final result. 
At the end of this session you will be able to:
Identify proper sample collection
Identify proper coagulation sample preparation
Explain the effect of pre-analytical variables on coagulation results
Define the effect of time and temperature on coagulation results
