What are two tests performed in the POL for immunology testing?

1. Immunoglobulin (Ig) assay: Measures the levels of various Ig classes (IgA, IgG, IgM, IgD, and IgE) in the blood. Ig levels can be abnormal in various diseases, such as immunodeficiency, autoimmune disorders, and certain infections.

2. Autoimmune antibodies: Screens for the presence of autoantibodies, which are antibodies that mistakenly attack the body's own tissues. Autoimmune antibodies can occur due to autoimmune diseases like rheumatoid arthritis, lupus, and thyroid diseases.
