WBC (nuclear) scan

The health care provider will occasionally request that antibiotics be stopped before this test.

How the test will feel:

There is a sharp prick from the needle during blood sampling and again when the blood is returned to you. The scan itself is painless, although the table that you are asked to lie on may be hard or cold. You do not feel the radioactive material.

Why the test is performed:

WBC scan is most often performed when the health care provider suspects a hidden infection. It is particularly useful for suspected infection or inflammation within the abdomen. This test may be advised when there is suspected pyelonephritis, abscess, or osteomyelitis. It also may be advised when there is an unexplained fever, particularly after surgery.
