Advanced blood test to identify and measure specific IgE antibodies against various allergens.

Immune function testing measures the activity and composition of your immune system's key players — including natural killer (NK) cells, T-cells, B-cells, and immunoglobulins. NK cells are your body's first line of defense against viral infections and abnormal cells. Lymphocyte subset analysis breaks down your immune cell populations to identify deficiencies or imbalances that may explain recurrent infections, slow healing, or increased susceptibility to illness. These tests are valuable for people with chronic infections, autoimmune conditions, or those seeking to optimize immune resilience as part of a longevity protocol.

Who Is This For?

People with recurrent infections or slow recovery from illness. Those with autoimmune conditions wanting immune system monitoring. Longevity-focused individuals tracking immune health. Anyone post-illness wanting to assess immune recovery.

What's Included

Immune cell population analysis
NK cell activity measurement
Results with reference ranges
Clinical interpretation

Preparation Required

No fasting typically required. Avoid intense exercise for 24 hours before testing as it temporarily alters immune cell counts. Inform the clinic of any immunosuppressive medications.

Biomarkers Tested

1
Immunoglobulin E (IgE) ng/mL

Immunoglobulin E (IgE) is a protein associated with allergic reactions that is normally found in very small amounts in the blood. IgE functions as part of the body's immune system (its defence against 'intruders').
