Egg vitellus
Egg Yolk (Egg vitellus) is a laboratory test that measures allergen-specific IgE antibodies to egg yolk proteins. The test helps identify sensitization to this food allergen and determine the possible cause of allergic reactions occurring after the consumption of eggs or foods containing egg yolk. Test results should be interpreted in conjunction with the patient's clinical history and symptoms.
Indications
The test is recommended for individuals who develop the following symptoms after consuming eggs or foods containing egg yolk:
- skin rash, hives, or itching;
- swelling of the lips, tongue, or face;
- nausea, abdominal pain, vomiting, or diarrhea;
- nasal congestion, sneezing, or difficulty breathing after consuming the food;
- suspected egg allergy;
- monitoring sensitization in patients with a known egg allergy.
Method
Determination of allergen-specific IgE antibodies to Egg Yolk (Egg vitellus) by immunoassay.
Procedure
The test is performed using a venous blood sample. The laboratory measures the presence and concentration of allergen-specific IgE antibodies to egg yolk proteins. The detection of these antibodies indicates sensitization to this allergen; however, it does not always confirm clinically significant allergy. The results should be interpreted together with the patient's symptoms and medical history.
Preparation:
- No special preparation is required.
- Fasting before blood collection is not required.
- The use of antihistamines does not affect the test result, as the analysis is performed on a blood sample and measures allergen-specific IgE antibodies.
- Patients are advised to inform their physician about any medications they are taking and any history of allergic reactions to ensure accurate interpretation of the results.
