FAQs
How is the rice allergy test performed?
During this blood test, a healthcare professional will take a small amount of blood from a vein in your arm using a small needle, which is then collected in a test tube or vial. This procedure lasts for less than a few minutes
What are the risks associated with the rice allergy test?
There are no known risks associated with this test. During a blood test, one may experience minor pain or bruising where the needle was inserted, but most symptoms will subside quickly
What is the turnaround time (TAT) for the IgE-based rice allergy blood test?
Test results of an IgE-based blood test are usually available after 2-3 working days. Test results might be mailed or made available online through health portals. Your doctor might also contact you by phone or email to review your test findings or arrange a follow-up appointment
How can rice allergy occur?
9-, 14-, and 31-kDa protein bands are the main allergens present in rice. An allergic person's immune system reacts when they consume rice or rice-related products. The immune system produces IgE antibodies to fight against these allergens because it perceives certain proteins or chemicals as harmful. Unfortunately, these antibodies lead to the release of the chemical histamine, that results in the symptoms of an allergic reaction
Are babies prone to rice allergy?
Yes, rice allergy is usually present in infancy. Be mindful, while feeding rice to your baby. It is advisable to consult your healthcare provider before introducing rice into your baby’s diet
