Definition & Meaning of "immunofixation blood test"

What is a "immunofixation blood test"?

A immunofixation blood test is a procedure used to identify specific types of proteins in the blood, particularly abnormal ones that can be a sign of diseases such as multiple myeloma or other blood disorders. During the test, a blood sample is mixed with antibodies that attach to these proteins, creating a pattern that is then analyzed to detect the presence and type of abnormal proteins. This test helps doctors diagnose and monitor conditions related to abnormal protein production.
