What is the purpose of this test?
Order this Whey Allergy IgE Blood Test to measure the IgE antibody levels in the blood to help detect an allergy to the milk protein whey. 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 is 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.
What causes an allergy to whey?
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.
