Re-evaluating peanut allergy: when it can be reassessed

Why re-evaluation is needed

Allergy status can change with age and changes in the body. Some people with peanut allergy may show improved tolerance years later, or may be able to tolerate peanut products in certain processed forms. Whether a change has occurred needs to be judged through proper assessment, not by testing yourself.

Factors usually considered in re-evaluation

• The time since the last clear reaction and how severe that reaction was
• Trends in relevant test results
• Age and reactions after past accidental exposure
• Whether it is possible to complete the assessment in a medical setting and manage any possible reaction

The right approach

Go to follow-up visits at the times your doctor arranges, and bring your symptom records and past test results. Until your doctor clearly agrees, you should still strictly avoid peanuts and peanut products, and pay attention to ingredient lists and cross-contact. If accidental exposure happens and a reaction occurs, record it promptly and seek medical assessment; this will affect later re-evaluation arrangements. For anyone who has had a severe reaction, any reintroduction should be done in a medical setting with emergency care available.
