Frequently asked questions
What is Ultratag?
Ultratag ™ RBC (Kit for the Preparation of Technetium Tc 99m Red Blood Cells Injection) is a sterile, nonpyrogenic, diagnostic kit for the in vitro preparation of Technetium Tc 99m Red Blood Cells Injection. Each kit consists of three separate nonradioactive components: 1. A 10 milliliter reaction vial containing: Stannous Chloride, Dihydrate (SnCl 2 •2H 2 O) – 50 mcg minimum Stannous Chloride, Dihydrate (SnCl 2 •2H 2 O) – 96 mcg theoretical Tin Chloride (Stannous and Stannic), Dihydrate (as SnCl 2 •2H 2 O) – 105 mcg maximum Sodium Citrate, Dihydrate – 3.67 mg Dextrose, Anhydrous – 5.5 mg Hydrochloric Acid – 0.47 mg Prior to lyophilization, the pH is adjusted to 7.1 to 7.2 with sodium hydroxide. The contents of the vial are lyophilized and stored under argon. 2. Syringe I contains: Sodium Hypochlorite – 0.6 mg in Sterile Water for Injection The total volume of this syringe is 0.6 mL. Sodium hydroxide may have been added for pH adjustment. The pH of this solution is 11 to 13. The syringe must be protected from light to prevent degradation of the light-sensitive sodium hypochlorite. 3. Syringe II contains: Citric Acid, Monohydrate – 8.7 mg Sodium Citrate, Dihydrate – 32.5 mg Dextrose, Anhydrous – 12 mg in Sterile Water for Injection The total volume of this syringe is 1 mL. The pH range of this solution is adjusted to 4.5 to 5.5 with sodium citrate or citric acid as needed.
