Immune response
The immune system detects the antigen
Antibodies
When the body detects the antigen and produces
Anaphylactic shock
Cardiovascular collapse and hypotension are present this life threatening response can be referred to
Ige medicated anaphylactic reaction
The type of antibody that is produced specific to anaphylaxis is called immunoglobulin e and is abbreviated as ige
Hypersensitivity
That at some subsequent time when the person is again exposed to that same antigen and ige antibodies are present an anaphylactic reaction can occur
Sensitization
First exposure to an antigen
Histamine
The primary chemical mediator released from mast cells and basophils
Anaphylactoid reaction
Non ige mediated reaction. A reaction with no sensitization is required is
Non ige mediated reaction
Or anaphylactoid reaction
