Effects of sequential reagent addition on technetium-99m red blood cell labeling efficiency using the UltraTag kit.

OBJECTIVE The purpose of this study was to investigate how the reagent-adding sequence affects 99mTc red blood cell (RBC) labeling efficiency using the UltraTag RBC kit. METHODS The package insert for preparation and quality control was followed during the experiment. The reagent-adding sequences were then altered during preparation. RESULTS If acid… (More)
