What is this test?
This test looks for IgE antibodies directed against wormwood, also known as Artemisia absinthium. It is reported as positive, negative, or another qualitative interpretation. The code is marked as deprecated, so the laboratory may use a different test or reporting method.
Why might I need this test?
A clinician may order this test when symptoms such as sneezing, wheezing, hives, or swelling occur after exposure to wormwood or related plants. It can help identify whether wormwood is a possible allergen.
How is the test performed?
A laboratory sample is tested for allergen-specific IgE using an immunoassay or a comparable allergy-testing method. The exact specimen and method are not clearly identified by this code, so they should be confirmed with the testing laboratory.
How do I prepare for the test?
Preparation depends on the laboratory method. Follow the clinician's or laboratory's instructions, including any advice about temporarily stopping allergy medicines. Do not stop prescribed medicines unless your clinician specifically tells you to do so.
Reference range
Adult: 10-40 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
A positive result indicates that IgE directed against wormwood is detectable and may support allergic sensitization. It does not by itself confirm that wormwood causes a person's symptoms, because sensitization and clinical allergy are not always the same. A negative result makes a wormwood allergy less likely but does not completely exclude it.
Short name
Wormwood IgE
