1. Study Purpose

   The purpose of this study was to determine the effects of using extension tubing connected to an IV catheter during blood collection and patient anticoagulant therapy on hemolysis rates among coagulation specimens.

   Summary of Findings:

   While some patients in this study were on anticoagulant therapy and others were not, there was no significant difference in rates of hemolysis between specimens from the two groups. There was also no significant difference in the rates of hemolysis (>0 mg/dL) between specimens collected with the use of extension tubing (33%) and without the use of extension tubing (33%).
