The flaxseed allergy test is a blood test that checks for an allergic response to flaxseed. It is ordered when a person has had symptoms such as hives, swelling, or difficulty breathing after eating or touching flaxseed, and the cause is unclear.
What it measures
- Flaxseed-specific IgE — Your immune system makes this antibody when it reacts to flaxseed proteins.
- Total IgE — A general measure of allergic tendency, not specific to flaxseed.
- Other seed-specific IgE — May include sesame, sunflower, or poppy seed to check for related allergies.
Who it is for
This test is typically ordered by an allergist, immunologist, or primary care clinician for people with unexplained allergic symptoms after exposure to flaxseed.
Preparation
No fasting or special preparation is required. Tell your clinician about all medications, especially antihistamines, as they may affect results.
Results and what they mean
Results are reported as a level of flaxseed-specific IgE, often with a reference range. A clinician interprets the result along with your symptoms and history. This is general information, not medical advice; discuss your results with a qualified healthcare professional.

Frequently asked questions
What does a positive result mean?
It means your blood contains antibodies that react to flaxseed. It does not always mean you will have symptoms, so a clinician uses it with your history.
Do I need to avoid flaxseed before the test?
No. Avoiding flaxseed is not required before the test. Continue your normal diet unless your clinician says otherwise.
How long does it take to get results?
Typical turnaround is 1 to 3 business days after the sample reaches the lab.
Can this test alone diagnose a flaxseed allergy?
No. It is one piece of information. A clinician may also consider your symptoms, a food diary, or other tests.
