IMMUNOLOGY

Detailed explanation-1: -The Th2 immune response, culminating in eosinophilia and IgE production, is not only characteristic of allergy but also of infection by parasitic worms (helminths).

Detailed explanation-2: -IgE-mediated food allergies cause your child’s immune system to react abnormally when exposed to one or more specific foods such as milk, egg, wheat or nuts. Children with this type of food allergy will react quickly-within a few minutes to a few hours.

Detailed explanation-3: -Common allergic reactions, such as hay fever, certain types of asthma, and hives are linked to an antibody produced by the body called immunoglobulin E (IgE). Each IgE antibody can be very specific, reacting against certain pollens and other allergens.

Detailed explanation-4: -The IgE Response is a Physiological Immune Response to Helminth Infection. The parallels between allergy and the immune response to parasitic worms (helminths) have been noted for some time.

Detailed explanation-5: -An allergen-specific immunoglobulin E (IgE) test is a blood test that measures the levels of different IgE antibodies in a person’s blood. Allergen-specific IgE tests are sometimes used to diagnose and better manage food allergies. They can also be helpful for environmental allergy diagnosis in some cases.

Detailed explanation-6: -An allergy blood test measures a substance called immunoglobulin E (IgE) in your blood. IgE is an antibody that your body makes. If you have allergies, you may have more IgE in your blood than normal. Allergies are a common, long-term condition that involves your immune system.
