What is the purpose of this test?

The 30 Food Additives, Colorings, & Preservatives Panel - ALCAT Test Kit is a diagnostic test that evaluates immune reactions by stimulating leukocytes. It is designed to identify sensitivities to 30 different food additives, preservatives, and food colorings, which are known to cause adverse reactions in some individuals. The panel is particularly useful for people who experience unexplained symptoms, such as headaches, digestive problems, and skin rashes, after consuming certain foods or beverages.

The test is conducted by exposing the patient's white blood cells (leukocytes) to the specific food additives, preservatives, and colorings. If the person is sensitive to any of these substances, the leukocytes will release histamine and other inflammatory compounds, indicating an immune response. The panel measures the extent of this response and provides a detailed report of the patient's sensitivities to each of the tested additives.

It is important to note that this test cannot be ordered for patients who are younger than six months old. Also, it is recommended that patients consult with a healthcare provider before ordering the test to ensure appropriate testing and interpretation of results.
