Signs and symptoms include a runny or stuffy nose, sneezing, red, itchy, and watery eyes, and swelling around the eyes. [1] The fluid from the nose is usually clear. [ 2 ] Symptom onset is often within minutes following allergen exposure, and can affect sleep and the ability to work or study.
Due to this binding, if the amounts of antigen and antibody in the blood are equal, each antibody molecule will be in a complex and be undetectable by standard techniques. The antigen, which is bound as well, will also be undetectable. [9] The antibody or antigen is only detectable in the blood when there is substantially more of one than the ...
Common variable immunodeficiency (CVID) is an inborn immune disorder characterized by recurrent infections and low antibody levels, specifically in immunoglobulin (Ig) types IgG, IgM, and IgA. [2] Symptoms generally include high susceptibility to pathogens, chronic lung disease, as well as inflammation and infection of the gastrointestinal ...
Red eyes, itchy rash, vomiting, runny nose, shortness of breath, swelling, sneezing, and cough: Types: Hay fever, food allergies, atopic dermatitis, allergic asthma, anaphylaxis [1] Causes: Genetic and environmental factors [2] Diagnostic method: Based on symptoms, skin prick test, blood test [3] Differential diagnosis: Food intolerances, food ...
Each antibody binds to a specific antigen in a highly specific interaction analogous to a lock and key.. An antibody (Ab) or immunoglobulin (Ig) is a large, Y-shaped protein belonging to the immunoglobulin superfamily which is used by the immune system to identify and neutralize antigens such as bacteria and viruses, including those that cause disease.

An illustration that shows how antigens induce the immune system response by interacting with an antibody that matches the molecular structure of an antigen. In immunology, an antigen (Ag) is a molecule, moiety, foreign particulate matter, or an allergen, such as pollen, that can bind to a specific antibody or T-cell receptor. [1]
