This Platinum Plus ALCAT Test Kit tests for 250 food intolerances, 30 food additives/colorings and environmental chemicals, 50 functional foods and medicinal herbs and 20 molds that can activate the immune system, and 20 antibiotics/anti-inflammatory agents. It measures changes in size and volume of white blood cells in response to challenges with foods. This is a tolerance test, not an allergy test. Note: This is a pre-paid shipping test kit that will be mailed and it requires a blood draw. Please contact your local hospital, clinic or phlebotomy service for lab specimen collection.
