A strong immune system requires a balance between activation and regulation—too weak, and we succumb to infections; too strong, and we face autoimmunity.
The Immune Function BioMap evaluates immune cell function, inflammation levels, antibody response, and essential nutrient status, giving a comprehensive picture of immunity.
Did you know: over 70% of the immune system lives in the gut. When your gut isn’t right, you’re not right.
BioMap included tests are listed below.

CBC examines the three major components of blood: RBCs, WBCs, and Platelets.
Tested biomarkers: 33
To assess immune function via CBC, prioritize WBC count, neutrophils, lymphocytes, and eosinophils—these biomarkers offer the clearest and earliest signals of immune imbalance.
WBC Count: broad indicator of immune system activity; elevated in infection/inflammation, low in immune suppression.
Neutrophils: first-line defense against bacteria and acute inflammation; elevated in bacterial infections or stress.
Lymphocytes: reflect viral response, adaptive immunity; low in chronic stress, high in viral infections.
Eosinophils: key in allergic responses, asthma, and parasitic infections — often overlooked, but insightful in immune dysregulation panels.

Ferritin is well known as the primary storage protein for iron, but it also plays a key role in the immune system—both in supporting and regulating immune responses.
Immune cells like T cells, B cells, and macrophages rely on iron to proliferate and function. Low ferritin = low iron = weakened immune response (fatigue, poor wound healing, greater infection risk)
Additionally, many pathogens (bacteria, viruses) need iron to replicate. During infection or inflammation, the body raises ferritin levels to sequester iron and keep it away from microbes This is why ferritin levels often go up during infection or inflammation—even if your iron levels are low. This is part of the innate immune defense, known as "nutritional immunity."

hs-CRP (high-sensitivity C-reactive protein) is a key marker of systemic inflammation and plays an active role in the innate immune response
hs-CRP acts as both a marker and a modulator of immune activity, helping the body recognize and respond to infection and tissue damage while offering insight into chronic inflammatory conditions.
hs-CRP is a much more sensitive version of the CRP test, able to detect very low levels of CRP in the blood. It’s often used to detect low-grade, chronic inflammation (e.g., in cardiovascular disease, autoimmune conditions).

IgG is the most abundant antibody in the human body and plays a central role in long-term immune defense.
Produced later in the immune response, it helps neutralize pathogens, activate other immune cells, and build immunological memory.
IgG levels provide valuable insight into both past exposures and the immune system’s ongoing ability to recognize and respond to threats.

Reference range: 50–300 mg/dL
IgM is the first antibody produced by the immune system in response to a new infection.
Found primarily in the blood and lymphatic fluid, it plays a critical role in early immune defense, helping to neutralize pathogens before more specialized antibodies are produced.
Due to its early appearance, IgM is often used as a marker of recent or acute infection.
-
Reference range: 47–310 mg/dL
IgA is a type of antibody primarily found in the mucosal linings of the respiratory and digestive tracts.
It serves as the body's first line of immune defense, neutralizing pathogens before they can enter the bloodstream.
IgA plays a key role in protecting against infections in the lungs, gut, sinuses, and saliva.

Vitamin D is known for its role in maintaining bone health, but it is also a key player in immune regulation, and low levels can significantly impair your body’s ability to fight infections, regulate inflammation, and prevent autoimmune dysfunction.
Vitamin D is your immune system’s thermostat—it activates the defenses when needed, and calms them down when they’re overreacting. Deficiency weakens your ability to fight infection and increases your risk of chronic and autoimmune diseases.
When vitamin D is low, your innate immune system becomes sluggish—slower to detect and kill invaders.
