Immunofixation blood test

Serum immunofixation

 

The immunofixation blood test is used to identify proteins called immunoglobulins in blood. Too much of the same immunoglobulin is usually due to different types of blood cancer. Immunoglobulins are antibodies that help your body fight infection.

How the Test is Performed

 

A blood sample is needed.

 

How to Prepare for the Test

 

There is no special preparation for this test.

 

How the Test will Feel

 

When the needle is inserted to draw blood, some people feel moderate pain. Others feel only a prick or stinging. Afterward, there may be some throbbing or a slight bruise. This soon goes away.

 

Why the Test is Performed

 

This test is most often used to check the levels of antibodies associated with certain cancers and other disorders.

 

Normal Results

 

A normal (negative) result means that the blood sample had normal types of immunoglobulins. The level of one immunoglobulin was not higher than any other.

 

What Abnormal Results Mean

 

An abnormal result may be due to:

  • Amyloidosis (buildup of abnormal proteins in tissues and organs)
  • Leukemia or Waldenstrom macroglobulinemia (types of white blood cell cancers)
  • Lymphoma (cancer of the lymph tissue)
  • Monoclonal gammopathy of unknown significance (MGUS)
  • Multiple myeloma (a type of blood cancer)
  • Other cancers

 

Risks

 

There is very little risk involved with having your blood taken. Veins and arteries vary in size from one person to another and from one side of the body to the other. Taking blood from some people may be more difficult than from others.

Other risks associated with having blood drawn are slight but may include:

  • Excessive bleeding
  • Fainting or feeling lightheaded
  • Hematoma (blood accumulating under the skin)
  • Infection (a slight risk any time the skin is broken)

    Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. Preparation may vary depending on the specific test.
