Allergy - Fig Test in Delhi

Allergies are basically hypersensitivity caused by exposure to a particular antigen or allergen resulting in a marked increase in reactivity to that antigen on subsequent exposure, sometimes resulting in harmful immunologic consequences. This overreaction by the immune system seldom results in symptoms such as sneezing, itching, rashes or even difficulty in breathing and swallowing too. One can even develop hypersensitivity to drugs and certain biological materials. Severe allergic reactions such as anaphylaxis and angioedema of the glottis can cause systemic shock and even death in some cases. This commonly requires immediate therapy with subcutaneous epinephrine or IV steroids.
