ALCAT Diet

Also Known As: ALCAT, Antigen Leukocyte Cellular Antibody Test, ALCAT Diet

The antigen leukocyte cellular antibody test (ALCAT) is a procedure created by American Medical Testing Laboratories and now marketed by Cell Science Systems, of Deerfield Beach, Florida, also known as ALCAT Diagnostic Systems. They marketed the procedure as an in-vitro screening test for adverse reactions to specific foods, food additives, food colourings and other chemicals, between 1984 and 1986. Since this time the original test method has been modified.

Journal articles, reviews, and allergology associations' position papers have characterized the ALCAT as an "unproven method" for diagnosing allergies, advised against its use, and concluded that relying upon the results of this test may lead to inappropriate advice and treatments.[1][2][3][4] A review by Gerez et al writes that itis an inappropriate modality for testing food allergy in clinical practice mainly because of its poor reproducibility, as well as its a lack of scientific and clinical proof of efficacy.

Researchers from Dubai published an uncontrolled, unblinded primary study asserting the effectiveness of custom diets based on individual ALCAT "food sensitivity" test results for weight loss.[7]
