An RBC (Red Blood Cell) Scan for GI (Gastrointestinal) Bleeding, also known as a GI Bleeding Scan, is a specialized nuclear medicine test used to detect, locate, and often determine the severity of active bleeding within the gastrointestinal tract. This scan is critical as rapid diagnosis and treatment can prevent complications and, in severe cases, save lives.

In an RBC Scan, a small amount of a patient's blood is removed, tagged with a radioactive substance, and then re-injected into the body. This tagged blood travels through the bloodstream and a gamma camera captures images over time, highlighting areas of active bleeding.
To ensure the most accurate results, it's important to follow certain instructions when preparing for an RBC Scan for GI Bleeding:
Fasting is typically required for several hours before the test.
Medications that can affect the gastrointestinal system, such as antacids, PPIs, or anti- inflammatory drugs, may need to be paused. Always consult your doctor about your medications.
Notify your doctor if you're pregnant or breastfeeding as the radioactive material used may present risks.
Alert your doctor to any allergies, especially if you have had a reaction to radiographic contrast materials.
During this scan, a small amount of your blood will be drawn, mixed with a radioactive material, and then re-injected into your body. A special camera will then take images of your body at different intervals to track the movement of the tagged red blood cells and pinpoint any active bleeding.
This scan is crucial for diagnosing active gastrointestinal bleeding, particularly when other tests have not provided clear results. It can guide treatment decisions and help prevent serious complications associated with gastrointestinal bleeding.
You may need this scan if you have symptoms of gastrointestinal bleeding, such as bloody or black stools, vomiting blood, or unexplained abdominal pain. Your doctor will decide based on your symptoms and overall health condition.
The frequency of this scan depends on your individual health condition. It's not a routine test, but is used when there is a suspicion of gastrointestinal bleeding.
While the scan is generally safe, it does involve exposure to a small amount of radiation. Rarely, there may be an allergic reaction to the radioactive tracer. Inform your doctor about any allergies or if you're pregnant or breastfeeding.
Abnormal results may indicate active gastrointestinal bleeding. Your doctor will discuss these findings with you and may recommend additional tests or treatments.
If your results are abnormal, discuss them with your doctor who may refer you to a gastroenterologist or surgeon, depending on the source and severity of the bleeding.
RBC Scan for GI Bleeding is a vital tool for diagnosing and managing active bleeding within the gastrointestinal tract. It's important to understand this test, follow preparation instructions, and discuss any concerns with your doctor. Remember, early diagnosis and intervention can significantly improve the prognosis for gastrointestinal bleeding.
