Question
I had a skin prick test and saw a huge panel of positives. However, I have had these foods and did not have an allergic reaction. Can I eat these foods? Could some of these be false positives?
Answer

False positives are common and can occur up to 50% of the time. This is why food testing panels are not recommended. If you tolerate the foods without adverse events then the test is a false positive. You can learn more about food allergies here.
