The cytotoxic food test was not found to be an accurate method for diagnosing atopic reactions to foods. Claims that the test correlated with other untoward reactions to foods (eg, headache, diarrhea, fatigue) could not be corroborated. The test itself is time-consuming, dependent on subjective interpretation, and inconsistent in results when repetitive runs are performed on the same patient.
