Peanut sensitivity is often confused with peanut allergy. Unlike peanut allergy (which produces IgE antibodies), an individual produces IgG and IgA antibodies against peanut antigens in peanut sensitivity. Peanut sensitivity symptoms, like all other food sensitivity symptoms, are often delayed (takes hours to days), hence diagnosis of the exact sensitivity is nearly impossible and often misdiagnosed.
Peanut sensitivity is rarely outgrown with age. The best solution to reduce peanut-related incidences is to avoid peanut-containing food. But, it is highly unfeasible to completely avoid peanut containing foods, since most processed foods use peanuts as a food ingredient. Hence, there is a high possibility that you may get accidental exposure anytime you eat from a restaurant. Peanut sensitivity is not life-threatening like peanut allergy, but can develop into allergy and other future health problems if not diagnosed early. Also, early detection of peanut sensitivity will help to identify a proper individualized management plan and enable confidence in dietary and social activities.
Only healthcare providers licensed in their state may order laboratory testing.
