What is used to label red blood cells?

Currently, red blood cells can be labeled with Tc-99m by in vivo and in vitro techniques.

What is Ultratag?

Ultratag RBC (technetium tc 99m-labeled red blood cells kit) is a diagnostic radiopharmaceutical used for blood pool imaging, including cardiac first pass and gated equilibrium imaging and for detection of sites of gastrointestinal bleeding.

What is blood cell Labelling?

Measurement of total red blood cell (RBC) volume. Measurement of RBC survival time. Identification of RBC destruction sites. Blood pool imaging studies (i.e. gastrointestinal bleeding)

What is Labelling in nuclear medicine?

Nuclear Medicine. Labels. Convenient Identification that Conforms to Government Standards. These labels are used for patients who have received gamma-emitting radionuclides. Printed in magenta ink on yellow background, labels are backed with a special adhesive for temporary adherence, without leaving a sticky residue.

What do you need to know about ultratag RBC?

Ultratag™ RBC (kit for the preparation of technetium Tc 99m-labeled red blood cells) is a sterile, nonpyrogenic, diagnostic kit for the in vitro preparation of technetium Tc 99m-labeled red blood cells. Each kit consists of three separate nonradioactive components:

What’s the dose of ultratag for red blood cells?

UltraTag RBC Dosage and Administration. The suggested dose range of technetium Tc 99m-labeled red blood cells in the average patient (70 kg) is 370 MBq (10 mCi) to 740 MBq (20 mCi). The patient dose should be measured by a suitable radioactivity calibration system immediately prior to administration.

How much sodium pertechnetate is in ultratag RBC?

Mix by gently inverting four to five times. Place the vial in a lead shield fitted with a lead cap and having a minimum wall thickness of 1/8 inch. 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.

What are the components of ultratag Tc 99m?

Each kit consists of three separate nonradioactive components: 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.
