The Necessity of Using Heparin in the UltraTag RBC Kit When Tagging Blood for a Nuclear Medicine Study.

Unlabelled: The purpose of this research was to evaluate the need to use heparin when preparing an UltraTag red blood cell (RBC) kit for a nuclear medicine study.

Methods: Nonheparinized blood samples (n = 15) and heparinized blood samples (n = 15) were added to UltraTag RBC kits. The samples were examined for macroscopic blood clotting and microscopic platelet clumping.
