Abstract
Food or chemical allergy and intolerance is determined by comparing an analysis for a given analyzable constituent of a polymorphonuclear leukocyte with and without incubation with the incriminated food or chemical. Allergy or intolerance to the food or chemical under consideration causes the leukocytes to break down releasing the analyzable constituent and permitting its presence to be determined.

A method of determining a food or chemical allergy or intolerance in a human individual comprising:
- (a) incubating a suspension of the individual's polymorphonuclear leukocytes with the food or the chemical suspected of causing an allergy or intolerance;
- (b) assaying the supernatant of said suspension for an intracellular constituent of said leukocytes, said constituent being released to the supernatant due to lysis of the leukocytes in a positive test;
- and
- (c) comparing the results of step (b) with the results of an assay of a second suspension of the individual's leukocytes which is unchallenged by the given food or chemical.
