Whey

This test measures the level of specific antibodies in your blood that react to whey, a primary protein found in cow's milk. It helps determine if your immune system views whey as harmful, which is useful for investigating symptoms like hives, stomach pain, or breathing trouble after consuming dairy. This testing helps doctors distinguish a potential milk protein allergy from other digestive issues. However, it cannot predict the severity of a future allergic reaction or diagnose lactose intolerance on its own.
