C3d Food Sensitivity Add-On

C3d is a stable marker of complement activation linked to IgG 1–3–mediated inflammatory food sensitivity reactions. When paired with IgG, IgG4, and IgA testing, it helps practitioners identify clinically relevant immune responses and prioritize dietary triggers.

Specimens are tested in duplicate on ELISA platform. We follow a diligent process to extract the key component from each analyte to ensure the antibody present in the patients’ serum will bind to it, and validate with positive and negative controls. The IgG and/or IgA antibodies, once bound to antigen, are detected through spectrophotometric analysis wherein the values are directly proportional to the concentration of the analytes in the sample.
