Cow milk

Allergen f2 corresponds to proteins of cow’s milk (Bos taurus) and is used to identify sensitization to this food product. The test is based on measuring specific IgE antibodies in blood serum and allows diagnosis of immediate-type allergic reactions. The most relevant allergens include casein, β-lactoglobulin, and α-lactalbumin. It is used both for targeted diagnostics and as part of extended allergy panels.

Indications

• Suspected allergy to cow’s milk or dairy products
• Skin reactions (rash, itching, urticaria, atopic dermatitis)
• Gastrointestinal symptoms (abdominal pain, diarrhea, vomiting)
• Respiratory symptoms (rhinitis, cough, bronchospasm)
• Reactions in infants to milk formulas
• Allergic reactions of unclear origin
• Extended allergy diagnostics

Procedure

Venous blood sampling is performed to determine the level of specific IgE to allergen f2 (cow’s milk).
The analysis is carried out in a laboratory, and results are reported in quantitative or semi-quantitative form depending on the method used.
