FAQ
What does this test measure? IgE antibodies specific to rice proteins in your blood, indicating allergic sensitization.
How accurate is this test? Highly reliable when combined with symptoms; correlates well with clinical allergies (EAACI 2023).
Can I eat rice before the test? Yes, no dietary restrictions needed—continue your normal eating habits.
What if my results are positive? Consult an allergist for next steps, including elimination diets or further testing.
How common are rice allergies? Rare in Western countries (0.7-2% of population) but higher among people with other allergies (Thermo Fisher 2025).
More Details
What is the purpose of this test?
The Rice Allergy IgE Blood Test measures immunoglobulin E (IgE) antibodies specific to rice proteins in your blood. When your immune system views rice as harmful, it produces these antibodies, leading to allergic symptoms ranging from mild skin reactions to severe respiratory issues. This test provides objective evidence of rice sensitization, helping you and your healthcare provider determine if rice is causing your symptoms (Mayo Clinic 2025).
Who would benefit from this test?
This test is valuable for anyone experiencing unexplained allergic reactions that might be rice-related. Health-conscious consumers seeking clarity about chronic symptoms, individuals with atopic dermatitis or asthma, and those with family histories of food allergies particularly benefit. The test is also useful for monitoring existing rice allergies over time and supporting elimination diet decisions with concrete laboratory evidence (NIH 2023).
When should I order a Rice Allergy IgE Blood Test?
Order this test if you experience recurring allergic symptoms after eating or handling rice products. Common symptoms include skin reactions (hives, itching), digestive issues (diarrhea, cramping, vomiting), or respiratory problems (coughing, wheezing, shortness of breath). The test is also recommended before starting elimination diets or when your healthcare provider suspects rice allergy based on your symptom patterns and medical history.
How do I interpret the results?
IgE < 0.35 kU/L – Negative
- What it means: No rice allergy detected
- Typical action: Rice consumption likely safe
IgE 0.35–0.70 kU/L – Borderline
- What it means: Minimal sensitization
- Typical action: Monitor symptoms, consider avoiding rice
IgE 0.70–17.5 kU/L – Positive
- What it means: Likely rice allergy
- Typical action: Avoid rice, consult allergist
IgE > 17.5 kU/L – Strongly positive
- What it means: High allergy risk
- Typical action: Strict rice avoidance, emergency plan recommended
Results should always be interpreted alongside your clinical symptoms and discussed with a healthcare provider for personalized recommendations.

Pre-test preparation
No special preparation is required for this blood test. You don't need to fast or adjust medications unless specifically advised by your healthcare provider. Simply continue your regular diet and routine, then visit any Walk-In Lab location for a quick blood draw. The procedure takes just minutes and uses standard laboratory collection methods (Mayo Clinic 2025).
How often should I get tested?
- Initial screening for suspected rice allergy – Once, then as needed
- Monitoring known rice allergy – Every 1–2 years or if symptoms change
- After allergen avoidance periods – 6–12 months to assess sensitization levels
- Before considering rice reintroduction – Consult allergist for timing
Why early detection matters
Identifying rice allergies early prevents severe reactions and improves quality of life. Undiagnosed rice allergies can lead to chronic symptoms affecting skin, digestion, and breathing. Since rice appears in many unexpected foods—from certain beers and wines to baby foods and baked goods—knowing your allergy status helps you make informed dietary choices and avoid accidental exposures that could trigger dangerous anaphylactic reactions.
