How to Test for Peanut Allergy at Home: A Comprehensive Guide.

We have always known that peanuts are a very good source of protein, good fat, and fiber. 100 grams of peanuts have 26 grams of protein and many sports professionals consume peanuts in various forms.

Peanuts are not just for athletic purposes but it is also an essential ingredient for many in their comfort foods like jam and peanut butter toast and many other dishes. However, in the U.S.A. 6.1 million people have peanut allergies and if you are one of them then you must avoid peanuts at all costs.

Now, let’s understand on how to test for peanut allergy at home (in case its false positive).

An allergy test only shows you the possibility of having a certain allergy. It’s like the typical “be aware of wild animals” warning sign. It doesn’t mean that there will be a wild animal on the street BUT there’s definitely a chance of it happening. In your case though if you confess you have been eating peanuts your entire life then you could say there was no wild animal but you still saw the warning sign (positive blood test).

Your blood might simply show more IgE/IgG antibodies – making the result be positive – yet it never tells you directly if you have an actual allergy against a certain type of food or not. It’s only there for a rule-out and not for an actual answer.

It was most likely a false positive. If you never had any troubles eating peanuts then I don’t see any reason to stop. If you have your doubts though and want to know if you can actually have an allergic reaction I would recommend you doing a skin prick test (since it shows an actual visible physical reaction) or even better an Oral challenge test where you’ll eat bits of peanuts with doctors around. Those are usually really expensive though. Good luck fellow allergic!!

If you are sure about your allergy but have experienced some discomfort after consuming peanuts then you must test for a peanut allergy. Testing for an allergy is not a very elongated procedure and now you can test your peanut allergy from the comfort of your home. Let’s understand on how to test for peanut allergy at home.

  3. Food allergy- Food allergies are the most severe and life-threatening which can also cause shortness of breath, hives, cramping, or even anaphylaxis.

Standard Procedure for an at-home peanut allergy test

A peanut allergy test is diagnosed when IgE or immunoglobulins E is found in excessive amounts in your blood. Ig E is a crucial part of identifying peanut allergy as when a person with peanut allergy is exposed to peanuts or foods that consist of peanuts the body releases IgE antibodies to bind peanut protein which mistakenly identifies as allergens.

After the procedure of binding protein, IgE produces histamine that triggers a reaction in your immune system which is why when an allergy test is conducted the level of IgE is measured.
However, there is a standard that one should follow before doing to understand how to test for peanut allergy at home:

  • Step 1- Control peanut exposure. Start by consuming a small amount of peanut butter or a similar peanut-containing product. Observe any immediate allergic reactions such as hives, itching, swelling, or difficulty breathing.
