(kit for the preparation of technetium Tc 99m-labeled red blood cells)
This information is intended for U.S. healthcare professionals only.
The only FDA-approved in vitro red blood cell Tc 99m labeling agent with typical tagging efficiency of ≥95%.1
Consistently high labeling yields, even in the presence of certain medications.1,2
Excellent target-to-background ratio1 from in vitro labeling helps in obtaining quality images.3,4
Indication & Usage
Ultratag™ RBC (kit for the preparation of technetium Tc 99m-labeled red blood cells) are used for blood pool imaging, including cardiac first pass and gated equilibrium imaging and for detection of sites of gastrointestinal bleeding.
Important risk information
Warnings and precautions
- It is essential that the user follow the directions carefully and adhere to strict aseptic procedures during preparation.
- The contents of the Ultratag™ RBC (kit for 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.
- Ultratag™ RBC (kit for the preparation of 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.
Use in specific populations
- Breastfeeding: should be discontinued because Ultratag™ RBC (kit for the preparation of technetium Tc 99m-labeled red blood cells) is excreted in human milk.
- Safety and effectiveness in pediatric patients have not been established.
Frequently asked questions
Add 370 to 3700 MBq (10 to 100 mCi) sodium pertechnetate Tc 99m (in a volume of up to 3 mL) to the reaction vial, see package insert for additional details.
Safety and efficacy in pediatric patients have not been established.
It is recommended that the labeled red blood cells be administered within 30 minutes of preparation or as soon as possible thereafter. A small study showed that technetium Tc 99m-labeled red blood cells prepared with Ultratag™ RBC have equivalent in vivo labeling efficiency when administered both immediately after preparation (5 patients studied) and at 6 hours after preparation (6 patients studied) with a 24-hour labeling efficiency averaging 97% for both groups.
