Chromic Chloride Cr-51
Chromic Chloride Cr-51 is a radiopharmaceutical agent containing the radioactive isotope Chromium-51, used primarily in nuclear medicine for diagnostic studies. It is utilized to evaluate red blood cell survival and splenic function, as well as to detect gastrointestinal bleeding sites by tagging the patient's own red blood cells with radioactive chromium. This agent is administered intravenously and imaging is performed to track the tagged cells through the body.
A radioactive diagnostic agent used to assess red blood cell lifespan, splenic function, and detect sites of internal bleeding.

Primarily used for red blood cell survival studies to diagnose hemolytic anemia, evaluation of splenic function and size, and localization of gastrointestinal bleeding sites. Also used in大红细胞标记研究.
Chromium-51 binds to hemoglobin within red blood cells, tagging them with a radioactive marker. The tagged cells can then be tracked using gamma camera imaging to assess their survival, distribution, and rate of destruction.
This is a radioactive pharmaceutical requiring specialized handling, administration by qualified nuclear medicine personnel, and compliance with radiation safety regulations. Patients should be informed about radiation exposure. Contraindicated in pregnancy unless absolutely necessary. Blood samples must be handled appropriately for labeling.
