Milk Protein Component Allergy IgE Blood Test
The Milk Protein Component Allergy test measures IgE Antibodies for the whey and casein proteins found in cow’s milk to screen for allergic reactions.
This test measures IgE Antibodies for the Alpha-lactalbumin (f76) IgE, Beta-lactoglobulin (f77) IgE, which are two forms of Whey protein, and Casein (f78) IgE commonly found in cow’s milk to screen for allergic reactions.
The watery part of soured milk that separates from the curds during the cheese-making process is called whey protein. This protein is also a popular dietary supplement used by bodybuilders, athletes, and others who want additional protein in their diet. Two common forms of whey protein in milk and milk products are alpha-lactalbumin and beta-lactoglobulin. The other protein commonly found in milk and milk products is casein, which makes up around 80% of the proteins in milk. Casein protein also gives milk its defining white color. Like whey protein, casein is also offered as a dietary supplement that helps with recovery and reduces muscle breakdown by releasing amino acids.
In an individual with a milk protein allergy, the body's immune system, which usually combats infections, overreacts to the proteins in milk. This reaction is because the body thinks these proteins are harmful invaders like bacteria or viruses when the person drinks or eats a milk product. So the immune system responds by working very hard to combat the invader by producing IgE antibodies. But unfortunately, this causes an anaphylactic shock.
Symptoms of a milk protein allergic reaction can be mild or severe. A milk protein allergy can be potentially life-threatening. These symptoms may include:
- itching or tingling
- watery or swollen eyes
- abdominal cramps
- trouble breathing
- loss of consciousness
Milk protein allergy is common among children. However, some children with a milk allergy outgrow it as they age. Yet, some individuals do not outgrow these symptoms, which continue into adulthood. Individuals may order this test if they are experiencing or previously experienced allergy symptoms within 48 hours of consuming milk or milk products.
