Medical Definition of Sensitised culture
1. A live culture of an organism to which a specific antiserum is added; after the mixture is incubated for several minutes (during which the antibody in the serum combines with the organisms), the excess serum is removed by means of centrifugation, washing in physiologic saline solution, and recentrifugation; the sensitised organisms may then be resuspended in physiologic saline solution.
