Allergen - Whey by EIA, Serum

Overview

The Allergen - Whey by EIA test measures specific IgE antibodies against whey proteins in the blood. Whey is a major protein component of cow's milk and is commonly found in dairy products, infant formulas, protein supplements, and processed foods. This test helps identify sensitization to whey and assists in the diagnosis of milk protein allergy.

Why This Test Is Done

• Evaluate suspected whey or milk protein allergy
• Investigate symptoms occurring after consumption of dairy products
• Assess allergic reactions in infants, children, and adults
• Support allergy diagnosis and dietary management plans
• Monitor individuals with known food allergies

Symptoms of Whey Allergy

• Skin rash, itching, or hives
• Eczema flare-ups
• Swelling of lips, face, tongue, or throat
• Nausea, vomiting, or abdominal pain
• Diarrhea
• Wheezing, coughing, or shortness of breath
• Nasal congestion or runny nose
• Severe allergic reactions (anaphylaxis) in rare cases

Sample Required

Sample Type: Serum

Test Method

Method: Enzyme Immunoassay (EIA)

Preparation

• No fasting is usually required.
• Inform your healthcare provider about any medications or known allergies.
• Follow specific instructions provided by your physician or laboratory.

Understanding the Results

• Negative Result: No significant IgE sensitization to whey detected.
• Positive Result: Indicates sensitization to whey proteins and may suggest an allergic response when exposed.
• Results should always be interpreted along with clinical history and symptoms.

Who Should Consider This Test?

• Individuals experiencing allergic symptoms after consuming milk or dairy products
• Infants and children with suspected milk protein allergy
• People with unexplained skin, respiratory, or digestive allergic symptoms
• Patients requiring confirmation of specific food allergens
