Immunofixation - blood

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.

Blood test

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.
