Immunity test items include humoral immunity test, cellular immunity test, tumor marker test, autoantibody test and other tests. Patients need to choose the appropriate tests according to their own needs. 1. Humoral immunity test: It can detect whether the humoral immunity of the patient is impaired through serum immunoglobulin such as IgG, IgA, IgM, IgE and serum complement test. 2. Cellular immunity test: It is through the detection of the number and functional changes of T cells, B cells and NK cells, so as to understand the cellular immunity situation and detect whether the patient suffers from immunological diseases, such as hereditary immunodeficiency disease, AIDS, and so on. 3. Tumor marker test: Tumor marker test is done by drawing blood, which can reflect the presence of tumor chemicals, and is currently used in clinical screening for cancer. 4. Autoantibody test: such as anti-dsDNA, anti-Sm, anti-U1-RNP, anti-SSB, rheumatoid factor, etc., which play an important role in the screening and diagnosis of autoimmune diseases. 5. Others: Immunity test items also include infection immunity test, transplantation immunity test and so on. Patients should take into account their own situation and ask their doctors when the test results come out. Once the disease is diagnosed, it is recommended to actively cooperate with the doctor to take relevant treatment measures. In daily life, patients need to ensure adequate sleep and do not overwork.
