You perform tagged RBC studies by: 1. draw blood from a person who has a suspected internal bleed 2. A radioactive chemical is mixed with the blood 3. The blood is reinjected into the person again 4. When the person is scanned, the doctor can tell where the bleed is in the body because the scan can detect the radiactive RBCs as they come out of damaged body tissue
