Allergen, Food, Egg White
Also known as: EGG
Use
This test is used to detect allergen-specific IgE antibodies to egg white, which can help diagnose allergies related to egg white consumption. The quantification of allergen-specific IgE allows clinicians to assess the likelihood of clinical reactions in patients. Classifications of the IgE levels provide insights into the potential severity of allergic reactions.
Special Instructions
The test is performed using serum separator tubes, and it's crucial to separate serum from cells and transfer it to the appropriate transport tube within 2 hours of collection. This is essential for accurate allergen measurement. Multiple allergen orders should follow specific specimen collection instructions provided at the laboratory's resource site.
Limitations
Allergen-specific IgE levels may not always correlate with the severity of allergic reactions, as individual clinical responses can vary. Moreover, a negative result does not exclude the possibility of an allergic reaction, and clinical correlation with patient history and in vivo tests is essential. The test may also not identify all allergens relevant to a patient's symptoms.
