The reproducibility of the cytotoxic food test was studied with aliquots of the same blood sample done in duplicate, as well as repeatedly retesting the same patient. The effect on the test of ingestion of foods and of sublingual food drops was studied. The cytotoxic food test is found unreliable as a diagnostic test. It fluctuates considerably from day to day and from week to week without relation to the foods ingested or to the administration of sublingual food drops. The cytotoxic food test and sublingual provocative food test are both unreliable for diagnosis of food allergy.
