  • It is essential that the user follow the directions carefully and adhere to strict aseptic procedures during preparation.
  • The contents of the kit are intended only for use in the preparation of technetium Tc 99m-labeled red blood cells and are NOT to be administered directly to the patient.
  • The contents of this kit are not radioactive. After sodium pertechnetate Tc 99m is added, however, adequate shielding of the final preparation must be maintained.
  • Technetium Tc 99m-labeled red blood cells must be handled with care to ensure minimum radiation exposure to the patient, consistent with proper patient management, and to ensure minimum radiation exposure to occupational workers.
  • The labeled red blood cells must be reinjected only into the patient from whom the blood was drawn.
  • Nuclear medicine procedures involving withdrawal and reinjection of blood have the potential for transmission of blood borne pathogens. Procedures should be implemented to avoid administration errors and viral contamination of personnel during blood product labeling.
  • The labeled red blood cells be administered within 30 minutes of preparation or as soon as possible thereafter.
  • Radiopharmaceuticals should be used only by physicians who are qualified by specific training in the safe use and handling of radionuclides.


  • Breastfeeding: should be discontinued because Technetium Tc 99m is excreted in human milk.
  • Safety and effectiveness in pediatric patients have not been established.
