Overview
Beta-lactoglobulin (BLG) is a protein found in cow's milk and a common allergen for those with milk allergies. A blood test can measure an individual's BLG specific immune response to identify a milk allergy. This test is helpful when someone experiences allergic reactions to milk but doctors need to confirm the culprit and differentiate it from lactose intolerance.
Luckily for those that are allergic to beta-lactoglobulin is that it is heat sensitive, meaning while they cannot have it cold, when it is cooked or baked the allergy is either not triggered or much more tolerable.
An allergy to b-lactoglobulin will cause a person to experience symptoms such as rash, itching, hives, swelling around the face or throat, nausea, cramps, diarrhea, and constipation when they consume milk or products containing milk. Many people develop a milk allergy early in life. Some people's allergies subside as they grow older but some persist into adulthood.

- Hives or skin rashes
- Itching/swelling (especially of the lips/face/tongue/throat)
- Severe dizziness
- Trouble breathing
- Fast heartbeat

- Rapid or increased pulse
- Swollen throat or lump, making it difficult to breathe
- Low blood pressure
Extreme dizziness or loss of consciousness
Specific IgE measures the concentration of circulating allergen specific IgE for food allergen Beta-Lactoglobulin (Milk protein).
This test requires a blood sample. A tourniquet (elastic) band is placed tightly on the upper arm. The patient is then asked to make a fist. This helps in the build-up of blood filling the veins. The skin is disinfected before needle insertion and the blood sample is collected in vacutainer.
Both: Negative: < 0.35 IU/ml
Both: Positive: => 0.35 IU/ml
Detection of IgE antibodies indicates an increased likelihood of allergy to Beta-Lactoglobulin (Milk protein) that may be responsible for eliciting signs and symptoms. A negative result indicates that the symptoms are not due to Beta-Lactoglobulin (Milk protein) allergies and other differential diagnoses must be considered.
