The antigen leukocyte cellular antibody test (ALCAT) is a proprietary test created and promoted by American Medical Testing Laboratories and Cell Science Systems, of Deerfield Beach, Florida. They market the procedure as an in-vitro screening test for adverse reactions to specific foods, food additives, food colourings and other chemicals. The test has been reformulates several times. IT is generally considered to be an unproven test(1). “These results have been shown to not be reproducible, give different results when duplicate samples are analysed blindly, don’t correlate with those from conventional testing, and ‘diagnose’ food hypersensitivity in subjects with conditions where food allergy is not considered to play a pathogenic role.”(3) A recent supportive study can certainly be characterized in this way(2).
