TEST ID: Alcat Test for food and chemical sensitivity

DESCRIPTION: Cellular Reactions to Food, Chemicals and Other Substances


Clinical Use

The Alcat Test is now considered the, "gold standard" laboratory method for identification of non-IgE mediated reactions to over 400 different foods, chemicals, and other categories of substances. It is a functional response test and captures the final common pathway of many of the pathogenic mechanisms, immunologic, toxic, and pharmacologic, that underlie non-IgE mediated reactions to foods and chemicals.


Specimen Information

COLLECTION: Whole blood in sodium citrate tube.

SPECIMEN STABILITY: Stable at room temperature for 24-48 hrs.

REJECTION CRITERIA: Blood sample is over 48 hours old; grossly hemolyzed, icteric, and lipemic specimens; improper anticoagulant used.


Method

The impedance method of blood cell counting and sizing. (ROBOCat II)


Results Interpretation

The Alcat Test measures a patient's response to each test substance and then classifies each response as reactive, borderline or non-reactive. Based on these classifications, a customized elimination/rotation diet may be designed to effectively eliminate specific triggers of chronic immune system activation. By reducing the burden of immune triggers it is possible that normal body functions and immune system balance may be improved.
