The nettle allergy test is a blood test that checks for an allergic response to nettle pollen or nettle plant proteins. It is ordered when a person has symptoms such as sneezing, runny nose, itchy eyes, or hives after being around nettles or during nettle pollen season.
What it measures
- Specific IgE to nettle pollen — Measures antibodies your immune system makes against nettle pollen.
- Specific IgE to nettle plant extract — Measures antibodies against proteins from the nettle plant itself.
- Total IgE — A general measure of allergic tendency, sometimes included for context.
- Cross-reactive allergens — Checks for similar proteins in other plants that may cause related symptoms.
Who it is for
This test is usually ordered by an allergist, immunologist, or primary care clinician for people with unexplained allergy symptoms that may be linked to nettle exposure.
Preparation
No fasting or special preparation is needed. Tell your clinician about any antihistamines or other medications you take, as some can affect test results.
Results and what they mean
Results are reported as a number or class for each specific IgE marker, often alongside a reference range. A clinician interprets these results together with your symptoms and history. This information is general and not medical advice; discuss your results with a qualified healthcare professional.
