Food reaction test:
What to consider:
- Omalizumab (Xolair ®) is used to treat asthma und allergies and is a so called anti-IgE-antibody, which minimizes the number of IgE antibodies in the blood in case of an allergic reaction.
- Antihistamines reduces the effect of histamine and are used in case of an allergy. If an allergic reaction occurs there is a high concentration of Type E immunoglobulins in the blood. Therefore, it can be assumed that antihistamines have an effect on these IgE levels because they are used in case of allergies. However, there is no scientific documentation on the context.
