ALCAT Testing

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. It markets this test as a screening test for adverse reactions to specific foods, food additives, food colorings and other chemicals. The test has been reformulated several times. It is generally considered to be an unproven test.  “These results have been shown to not be reproducible, give different results when duplicate samples are analyzed 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.”  A recent supportive study is also open to being characterized in this way.
