Serum refers to a blood test that measures Asparagus-specific IgE antibodies in your serum (blood). It is used to determine whether your immune system is sensitized to asparagus and may be causing allergic reactions. The test is commonly performed using an enzyme immunoassay (EIA/FEIA) method.
What does it check?
It helps evaluate suspected allergy symptoms after exposure to asparagus, such as:
Itching or hives
Swelling of lips or throat
Wheezing or breathing difficulty
Stomach pain, nausea, or vomiting
Rarely, severe allergic reactions (anaphylaxis)
Sample required
Serum (blood sample)
Important note
A positive IgE result does not always mean you have a clinical allergy. It indicates sensitization to asparagus, and the result should be interpreted along with your symptoms and medical history.
