Total IgE is a single blood test to identify or eliminate whether a patient has classical IgE allergy issues. IgE is produced in the body as a response to allergens, parasitic infections and other disorders. For example, if a patient presents with a skin rash, hives and/or asthmatic symptoms, testing for elevated levels of total IgE can help a practitioner confirm that these symptoms are due to an allergic reaction. High total IgE may indicate a high probability of sensitization and could be useful in deciding whether further investigation is warranted. Follow-up tests can then be performed to determine the specific cause of the allergy. If the total IgE result is abnormal, consider testing for IgE antibodies to specific foods, inhalants, chemicals etc. These IgE panels are available on request.
If total IgE is within normal limits, consider other possibilities such as :
Whereas approximately only 2-5% of the population has a classical allergy to a food, it is also estimated that more than 70% of the population has some form of adverse reaction to one or more foods or additives, manifesting in a broad range of disorders such as; migraine headaches, weight gain, fatigue, hyperactivity/ADD, arthritis, respiratory and skin disorders, recurring ear infections in children, depression, IBS and various others.
Some patients (who are NOT IgE positive) produce strong, clear IgG antibody responses to “trigger foods” and are identified by the 40 or 93 food profiles (NB: the IgG tests can be carried out either by finger prick or venous sample).

Total IgE requires an unanticoagulated (clotted) serum sample
IgG Food Profiles require either an unanticoagulated serum sample OR a fingerprick sample.
