How Strong Is Your Immune System? Find Out With a Lab Test

Extensive screen for autoimmune disorders including antinuclear antibodies (ANA), C-reactive protein (CRP), Rheumatoid Factor (RF), Complement C3, Complement C4 and immunoglobins IgA/, IgG/IgM.

If you are suffering with rheumatoid arthritis, your health practitioner may want to measure antibodies known as rheumatoid factors that target aspects of the joints and the immune system.

Panel includes antibodies to Epstein Barr viral capsid antigen (VCA) IgG, Epstein Barr viral capsid antigen IgM and Epstein Barr nuclear antigen (EBNA), which can help identify EBV infection.

What we commonly refer to as herpes, or HHV-6, is composed of two viruses, HHV-6A and HHV-6B. Testing for the virus's IgG antibody is important since a high value may indicate infection or reactivation.

Testing for blood levels of IgG antibodies to cytomegalovirus can indicate past exposure to the virus, which infects an estimated 60-90% of adults. Chronic infection can have a negative impact on the immune system.

The T-Lymphocyte Helper/Suppressor Profile blood test measures T-helper (CD4+) cells and cytotoxic T-cells (CD8+) cells, which are types of white blood cells that are important for immune function.

The anti-SS-A/anti-SS-B blood test detects antibodies that help identify the presence of the autoimmune conditions Sjögren's syndrome and lupus with Sjögren overlap syndrome.

Natural killer (NK) cells are white blood cells in our immune system that help defend us from infection and/or prevent the progression of disease. This test assesses the number of CD3- and CD56+ types of NK cells to monitor immune function and more.

Natural killer (NK) cells are selective white blood cells in our immune system that help defend us from infection and/or prevent the progression of disease. This test assesses the number of CD4+ and CD8+ types of NK cells to monitor immune function and more.

Antinuclear antibody (ANA) blood testing is used in the screening of autoimmune disorders such as rheumatoid arthritis, scleroderma, Sjögren’s syndrome and often used to diagnose systemic lupus erythematosus (SLE).
