Also Known As
Milk Allergy Test, Allergen Profile for Milk
Purpose of the Dairy Allergy Test
A blood test for dairy allergy helps diagnose allergic reactions to milk and other dairy products. Positive results allow for the prescription of antihistamine medication.
Beta-lactoglobulin (f77) IgE (2852)
Casein (f78) IgE (2853)
Cheddar Cheese (f81) IgE (2858)
Cheese, mold type (f82) IgE (2859)
What Does the Dairy Blood Test Measure?
Dairy allergy testing detects immunoglobulin E (IgE), which is an antibody released in high amounts to fight off allergens in the body. Allergens are generally harmless, but the immune system mistakenly tags them as harmful substances.
For dairy products like whole milk, cheese, yogurt, etc., the allergic reaction is usually triggered by the alpha S1-casein protein found in the cow’s milk, leading to the production of increased IgE. However, in some cases, other milk proteins are identified as the culprits.
The following are the specific tests included in a dairy allergy test panel.
- Alpha-lactalbumin test
- Beta-lactoglobulin test
- Casein test
- Cheddar Cheese
- Cheese, mold type
Who Should Take a Blood Test for Milk Allergy?
You should take the test for dairy allergy if symptoms appear for over two weeks. If allergic reactions show up after consuming dairy, inform your doctor to confirm the medical connection.
Here are milk allergy symptoms to check out:
- Watery eyes
- Abdominal pain
- Nasal congestion
- Nausea and vomiting
- Coughing and wheezing
- Skin rashes (hives) and itchiness
- Diarrhea or loose stool with blood
- Swollen lips, face, tongue, and other body parts
It’s important to test for dairy allergy at the onset of the symptoms. Otherwise, you might increase your risk of anaphylaxis, which is a potentially fatal shock caused by allergies. This can be characterized by low blood pressure, weak pulse, breathing difficulty, narrow airways, severe digestive distress, rapid skin rash, and even death.
Dairy Allergy Blood Test Preparation
No special preparation is necessary prior to blood sample collection.
Dairy Allergy Test Panel Results
In the panel report, specific IgE is shown for each marker (alpha-lactalbumin, beta-lactoglobulin, casein, cheese, and milk). If your test results show a value higher than 0.10 kU/L, it confirms the elevation of IgE, which suggest milk or dairy allergy.
Getting such test results will direct your healthcare provider to prescribe antihistamine medications and restrict dairy consumption.
