Preanalytic Variables in Special Coagulation Testing
Clinical Implications
Conclusion
October 2008
In conclusion, I hope that I have been able to highlight the importance of preanalytic variables that affect results of coagulation testing and have been able to emphasize the importance of the specimen collection, processing and transport as being major factors among multiple variables.
Hopefully with this education effort, we may be able to reduce the number of clotted specimen events that will in the end benefit the most important person, the patient. Thank you for your attention.
