Our Total IgE test is useful on its own or in combination with an IgG, IgG4, or IgGA antibody assessment as an overall indicator of IgE levels. Elevated levels of the antibody has been tied to allergic response. This measurement is included in all IgE food and aeroallergen panels.
US BioTek runs all IgE panels on a sophisticated FDA-approved immunoassay analyzer that utilizes enzyme-amplified chemiluminescence technology. Chemiluminescence provides lower detection limits than conventional ELISA, making it particularly suitable for IgE detection, which can be hard to detect due to its short half-life compared to other immunoglobulins.
