What does the Immunofix ELP Serum test identify?

The Immunofix ELP (Electrophoresis) Serum test specifically focuses on identifying abnormal immunoglobulins in the serum. This test is commonly utilized to assist in diagnosing conditions related to protein disorders, such as multiple myeloma and other monoclonal gammopathies where an abnormal proliferation of immunoglobulin-producing cells occurs. The results of this test can reveal the presence and type of abnormal immunoglobulins, which is crucial for determining the nature of certain diseases and guiding treatment options.

In the context of the other options, the identification of normal proteins in serum pertains to standard serum protein electrophoresis rather than the specific abnormalities looked for in the Immunofix ELP test. Alpha-fetoprotein levels and beta-HCG levels are tumor markers primarily used for cancer screening, diagnosis, and monitoring, and they are not the focus of the Immunofix ELP Serum test. Hence, the correct answer accurately reflects the purpose and function of the test in a clinical setting.
