Order a whey allergy IgE blood test to detect an allergy to whey. This test measures the amount of allergen-specific antibodies in a blood sample. Whey is the liquid remaining after milk has been curdled and strained. It is one of two main proteins in milk, making up 20% of the protein in cow's milk.
Whey is the cloudy yellowish liquid expelled from cheese curds during the cheese-making process, and the liquid strained from fresh yogurt. Acidic whey, also known as sour whey, comes from yogurt and soft cheeses such as cottage or mozzarella. Sweet whey comes from harder cheeses produced with rennet, such as cheddar and swiss.
An allergy to whey triggers a reaction in an individual's immune system. The body views certain substances as toxic and produces IgE antibodies to these contaminants. These antibodies cause histamine to be released, which will cause the symptoms of an allergic reaction.
Allergy symptoms vary from one individual to the next ranging from mild to severe reactions, which can be experienced within minutes to hours after exposure. Common symptoms of a whey allergy may include one or more of the following symptoms:
- Runny nose
- Red eyes
- Watery eyes
- Stomach pain
