Abscess scan - radioactive
Definition
Radioactive abscess scan uses white blood cells tagged with radioactive indium and x-rays to find abscesses in the body.
Alternative Names
Radioactive abscess scan; Abscess scan
Why the Test is Performed
This test is used to identify an abscess in the body when a person has signs and symptoms of sepsis, or your health care provider wants to know the cause of surgical complications.
White blood cells are the body's means of fighting infection, and this test enables your health care provider to follow these cells and see if they are accumulating around a site of infection. It is expected that there will be groupings of white blood cells in the liver, spleen, and bone marrow, but if groupings of cells exist elsewhere, an abscess or other inflammatory process is possible.
How the Test is Performed
Blood is drawn from a vein, usually from the inside of the elbow or the back of the hand. The puncture site is cleaned with antiseptic. An elastic band is placed around the upper arm to apply pressure and cause the vein to swell with blood.
A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. During the procedure, the band is removed to restore circulation. Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.
The blood sample is then sent to the lab where they isolate the white blood cells (WBCs), and tag them with the radioactive substance, indium. The cells are then reinjected through another venipuncture.
You will have an appointment to return after 24 - 48 hours for the nuclear medicine scan component of this test in which clustering of WBCs outside the liver, spleen and bone marrow will be identified.
How to Prepare for the Test
You must wear a hospital gown and remove all jewelry.
Inform the health care provider if you are pregnant. This procedure is NOT advised if you are pregnant. If you are a premenopausal woman, you should use some form of birth control during the course of this procedure.
How the Test Will Feel
When the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.
The nuclear medicine scan is painless. There may be some discomfort lying flat and still on the scanning table for a short period of time.
Risks
- Some bruising may occur at the site of injection
- There is always a slight chance of infection when the skin is broken
There is low-level radiation exposure. Radioactive injections are monitored and regulated to provide the minimum amount of radiation exposure needed to produce the image. Most experts feel that the risk is very low compared with the benefits.
Pregnant women and children are more sensitive to the risks of the x-ray.
Considerations
Inform your health care provider if you have or had any of the following:
- Gallium (Ga) scan within the previous month (could interfere with test results)
- Hemodialysis (may cause a false negative)
- Hyperglycemia (may cause a false negative)
- Total parenteral (through an IV) nutrition (may cause a false negative)
- Steroid therapy (may cause a false negative)
- Long-term antibiotic therapy (may cause a false negative)
Normal Results
Normal findings would show no abnormal accumulation of white blood cells.
What Abnormal Results Mean
An accumulation of white blood cells outside of the normal areas indicate either an abscess or other type of inflammatory process.
