Dermal hypersensitivity reaction is an exaggerated immune response in the skin to certain substances or allergens. This reaction can lead to symptoms such as redness, itching, swelling, and rash at the site of contact with the allergen. Common causes include contact dermatitis, eczema, or allergic reactions to chemicals, plants, or certain metals.
An Arthus reaction is a hypersensitivity reaction involving the in situ formation of antigen/antibody complexes after the intradermal injection of an antigen.
A transfusion reaction is typically an acute hypersensitivity reaction to foreign red blood cells, which can occur immediately or within a few hours of the transfusion. Subacute hypersensitivity reactions usually take days to develop after exposure to the antigen, unlike the immediate onset of symptoms seen in transfusion reactions.
This is the hypersensitivity to a drug or other substance without any relation with thr immunological response.
Anaphylaxis is the term that describes an exaggerated life-threatening hypersensitivity reaction to a previously encountered antigen. It can lead to symptoms such as difficulty breathing, swelling, and a drop in blood pressure, requiring immediate medical attention.
IgE is the immunoglobulin associated with hypersensitivity reactions, such as allergies. When an allergen triggers the production of IgE antibodies, it can lead to a rapid immune response that causes symptoms like hives, itching, and even anaphylaxis.

Hypersensitivity
Hypersensitivity is also known as allergic reaction, exaggerated immune response, or allergic sensitivity.
Type IV
An Arthus reaction is a hypersensitivity reaction involving the in situ formation of antigen/antibody complexes after the intradermal injection of an antigen.
A transfusion reaction is typically an acute hypersensitivity reaction to foreign red blood cells, which can occur immediately or within a few hours of the transfusion. Subacute hypersensitivity reactions usually take days to develop after exposure to the antigen, unlike the immediate onset of symptoms seen in transfusion reactions.
they are all hypersensitivity reaction
It is an allergy
