How Accurate Are SPTs?

A MyFoodAllergyTeam Member

I was diagnosed with a peanut allergy when I was about 18 months old. My mom gave me peanut butter on crackers, but I didn't eat the snack, I just played with it and broke out in hives. She gave me a bath and the hives went away. I had a skin prick test when I was about 3 that confirmed a peanut allergy. I've never had a reaction to any food since, but I've also avoided all peanuts and nuts. I will usually eat food that says "May Contain Peanuts" on the label. I've never had an itchy mouth, never had any hives, never had any symptoms of any type of allergic reaction at any restaurant, anyone's house, anywhere at all. I recently heard skin prick tests are only 50% accurate. Is it possible that I was misdiagnosed? How likely is it that I've successfully avoided any peanuts and traces of peanuts for about 3 decades with zero reactions? Is this the norm, or is this unusual? Just wondering. :) Thanks in advance for any advice/opinions!

Blood tests are not accurate at all. Skin tests tend to be better indicators. But the best are oral food challenges, which I was freaked out to do. However, I did it - and am so glad I did. I know I am able to tolerate more than I thought. I was so scared that I would literally die from the tiniest crumb.

perfectly possible you have grown out. 20% of children grow out of it at around 7 years old. After that it is normally considered life long. I would have another test .

you can also have a blood test done. my son tested possitive for a nut allergy on both, and even if someone eats peanut butter and hugs him, he has a reaction.

For new member, STP tests at 3. Maybe an updated test would be a good thing. Put your mind to rest. If you have no symptoms, Im thinking a full blood work up would be wise. You can have celiac and not be diagnosed, but still be damageing your body. You may be anemic, low on iron, vitamin d, calcium, etc. In my case I wasnt diagnosed untill after aome high stress periods kicked it up enough to have symptoms excellerate and have new ones start. Iv had several drs who didnt catch it because of out dated educations.
