Immunology tests are laboratory tests that evaluate the immune system's function and responses. They help diagnose and monitor various immunological disorders, autoimmune diseases, allergies, and infections. These tests assess different aspects of the immune system, including the presence of specific antibodies, immune cell counts, and cytokine levels. Here are some common types of immunology tests:

1. Antibody Tests:

   • Antibody Titer: Measures the concentration of specific antibodies in the blood to assess immunity to a particular pathogen or vaccine.
   • Antinuclear Antibody (ANA) Test: 
   • Ds DNA Test
   • AntiCCP
   • Rheumatoid Factor (RF) Test:

2. Complement Tests:

   • Complement C3 and C4: Measure the levels of complement proteins in the blood. Abnormal levels can indicate autoimmune diseases and immune complex disorders  

3. Allergy Tests:

   • Specific IgE Blood Test: Measures the level of allergen-specific IgE antibodies in the blood to identify allergen triggers.

4. Autoimmune Disease Panels:

   • Systemic Lupus Erythematosus (SLE) Panel: Combines multiple tests to aid in the diagnosis of lupus.
   • Antiphospholipid Antibody Panel: Detects antibodies associated with antiphospholipid syndrome, which increases the risk of blood clots.

5. Immunoglobulin (Ig) Testing:

   • Quantitative Immunoglobulin (IgG, IgA, IgM) Measurement:  

These immunology tests are crucial for diagnosing and managing conditions related to the immune system and play a vital role in guiding treatment decisions and monitoring disease progression. The choice of specific tests depends on the clinical symptoms and suspected conditions of the patient.
