Do You Have a Robust Immune System? Find Out with a Lab Test

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.

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.

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.

Vitamin D is an essential nutrient. This simple 25-hydroxyvitamin D blood test can determine whether your levels fall within an optimal range.

One of the most common nutritional insufficiencies is having low blood levels of zinc. Take this test to find out whether your levels are appropriate, or whether you should make changes to your dietary or supplementation choices.

Vitamin C is an important nutrient that we do not create on our own and must get from food—which not all of us do reliably. This test checks for vitamin C deficiency, also known as scurvy.

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.

This panel assesses proteins involved in the production of thyroid hormones. It is possible for antibodies from your own immune system to attack these proteins, rendering them dysfunctional and resulting in fatigue, weight gain, constipation and other symptoms of low thyroid.

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.

Celiac disease is an immune-mediated reaction to gluten, resulting in inflammation and other medical symptoms. This panel includes tests for deamidated gliadin IgA, tissue transglutaminase IgA and serum IgA level.

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.

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.
