Preanalytic Variables in Special Coagulation Testing
Clinical Implications
Clotted Specimens as a Percentage of Test Volume
October 2008
Over a period of about one year, data was collected and analyzed. As shown, between 0.4 and 0.7 percent of all our specimens were clotted. This might not seem like a large number until one looks at the data in absolute terms.
