Hypersensitivity Reactions
Another name for Type I hypersensitivity.
What is anaphylactic hypersensitivity?
A type of allergy testing that is less expensive and more sensitive than serological tests.
What is direct skin testing?
Common lab test for type II hypersensitivity reactions.
What is a direct antiglobulin test or Coombs test?
Another name for type IV hypersensitivity.
What is delayed hypersensitivity?
The most widely used tumor marker and is often elevated in patients with prostate cancer.
What is Prostate-specific antigen (PSA)?
In Type I hypersensitivity, IgE antibody is produced and bind to these.
What are mast cell and basophils?
A type of allergy testing used to detect a number of common triggers like ragweed, trees, grasses, mold, animal dander, foods and insect venom.
What is Allergen-Specific IgE Testing?
Type III hypersensitivity differs from Type II hypersensitivity because of this.
What is antigen solubility?
Contact dermatitis like poison ivy or hypersensitivity pneumonitis are examples of this type of hypersensitivity.
What is type IV hypersensitivity reaction?
A clinical application of tumor markers where the response to cancer treatment is observed. Effective treatment is indicated by the decreasing levels of the marker over time.
What is monitoring?
Allergy symptoms are a result of this.
What is degranulation?
Also known as antibody-mediated cytotoxic hypersensitivity.
What is type II hypersensitivity?
A hypersensitivity reactions that occurs when an animal has a large amount of ciruclating antibody and is exposed to the antigen intradermally, resulting in localized deposition of immune complexes.
What is and Arthus reaction?
The best marker for ovarian cancer.
What is CA-125?
A clinical application of tumor markers to identify a cancer in asymptomatic individuals in a population.
In Type 1 hypersensitivity, the T cell subset that predominates, resulting in release of cytokines IL-4 and IL-13, which initiate production of IgE.
What are Th2 cells?
A type of hypersensitivity where IgG and IgM antibodies are directed against antigens on a cell surface resulting in cell damage, inhibition of cell function or over-stimulation of cell function.
What is Type II hypersensitivity?
A type III hypersensitivity reaction that results from the buildup on antibodies to animal serum used in passive immunization.
What is serum sickness?
A tumor marker used to detect breast cancer.
What is CA 15-3?
Biological substances that are increased in the blood, body fluids, or tissues of patients with a particular types of cancer. Used in cancer screening and diagnosis, determining patients prognosis, and monitoring patients response to therapy.
What are tumor markers?
Typical reaction following contact with pet dander or insect venom.
What is a wheel-and-flare reaction?
Transfusion reactions, hemolytic disease of the newborn, and autoimmune hemolytic anemia are examples of this type of hypersensitivity.
What are Type II hypersensitivity reactions?
Type IV hypersensitivity differs from the other 3 types of hypersensitivity because these play a major role in its manifestations.
What are sensitized T cells?
CA 19-9 is a tumor marker for this type of cancer.
What is pancreatic cancer?
A tumor marker associated with colorectal, breast and lung cancers.
What is carcinoembryonic antigen (CEA)?
