An abscess occurs when pus collects due to an infection. AbscessAn abscess is a collection of pus in any part of the body. In most cases, the area around an abscess is swollen and inflamed.Read Article Now Book Mark Article How the Test is Performed Blood is drawn from a vein, most often on the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood. Next, the provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm. The puncture site is covered to stop any bleeding. The blood sample is then sent to a lab. There the white blood cells are tagged with a radioactive substance (radioisotope) called indium. The cells are then injected back into a vein through another needle stick. RadioisotopeA positron emission tomography (PET) scan is a type of imaging test.

Others feel only a prick or sting. Afterward, there may be some throbbing.The nuclear medicine scan is painless. It may be a little uncomfortable to lie flat and still on the scanning table. This most often takes about an hour. Why the Test is Performed The test is rarely used today. In some cases, it may be helpful when doctors cannot localize an infection. The most common reason it is used is to look for a bone infection called osteomyelitis. It is also used to look for an abscess that may form after surgery or on its own. Symptoms of an abscess depend on where it is found, but may include:Fever that has lasted a few weeks without an explanation Not feeling well (malaise) Pain Other imaging tests such as an ultrasound or CT scan are often done first.
