Prausnitz-KÑŒstner reaction
- Prausnitz-KÑŒstner reaction
- a type I hypersensitivity reaction produced in a nonatopic subject by intradermal injection of serum from an atopic subject, followed 12 or more hours later by an injection of antigen into the same site; the presence of specific IgE antibody in the transferred serum results in a classic wheal and flare reaction to the antigen. Once the standard method of demonstrating IgE, this test is no longer used because of the risk of transmitting hepatitis and because serum IgE can now be measured by in vitro assays, e.g., RAST and RIST. Called also P-K r. or test and Prausnitz-KÑŒstner test.
