For best results, use tc99m from a generator eluted within 24 hours. The eluate should be used within 2 hours of elution.
Reconstitution Instructions:
- Snap off the plastic lid and place in appropriate lead shielding. Wipe the septum with 70% isopropyl alcohol and allow it to dry.
- Using a 10 mL syringe, draw up 100 mCi of tc99m (in approximately 2 mL) and inject into the ECD Buffer, being sure to withdraw an equal amount of gas from the vial to neutralize pressure.
- With a sterile syringe, inject 3 mL of 0.9% sodium chloride into the reaction vial to dissolve the contents. Remove an equal volume of air to maintain pressure within the vial. Shake the contents of the vial for a few seconds.
- With another sterile syringe, immediately (within 30 seconds) withdraw 1 mL out of the reaction vial and inject it into the buffer vial. Discard the reaction vial
- Swirl the contents of the buffer vial for a few seconds and allow this mixture to stand for 30 minutes at room temperature.
- Examine the vial contents for particulates and discoloration prior to patient administration. It should be clear of any particulates.
It is recommended that the kit be stored refrigerated until use; at such time the product should be aseptically withdrawn
Storage and Handling
This kit should be stored in the refrigerator prior to reconstitution and the reaction vial protected from light.
