Immunological testing programs include humoral immunity testing, cellular immunity testing, tumor marker testing, autoantibody testing, infection immunity testing, other immunity testing and other aspects of the examination program. 1. Humoral immunity test: (1) Immunoglobulin: reflecting the body’s humoral immune function status, helping to identify and diagnose infectious diseases, immunoproliferative diseases and immunodeficiency diseases. (2) Complement system: including total complement hemolytic activity test, complement C1, complement C3 test, helps to diagnose rheumatoid arthritis, systemic lupus erythematosus, malignant tumors and other diseases. 2. Cellular immunity test: mainly detects T-cell subpopulation, B-lymphocyte differentiation antigen, cytokine, natural killer cell immunity test, which is used to judge cellular immunity function. 3. Tumor marker test: such as protein tumor marker, enzyme tumor marker, hormone tumor marker and other tests, which are of great value for tumor diagnosis, efficacy and recurrence judgment. 4. Autoantibody test: including rheumatoid factor, anti-nuclear antibody, anti-tissue cell antibody and other tests, which can be used to diagnose rheumatic immune diseases, hyperthyroidism and other diseases. 5. Infection immunity test: including bacterial, viral, parasitic and other infections. 6. Other immunological tests: such as calcitoninogen test, C-reactive protein test, specific lgE test, etc. It is recommended that patients in need of immunological testing to the hospital, the examination program can be specific to the doctor for detailed consultation.
