Can you test negative for a food allergy but actually be allergic?

False negative test results can occur, but they're pretty rare, thankfully. So, especially when somebody doesn't have a very good history of having reactions to foods, we tend to believe our negative test results in both skin testing and blood testing.

The gold standard to diagnose food allergy or to rule it out, is the oral food challenge. So, when the clinical history is indeterminate, or the testing is indeterminate, or we have somebody with known food allergy, and we feel that they may have developed tolerance over time, through repeat testing, the best test is to have a supervised graded oral food challenge, where you eat gradually increasing amounts of the food, in the presence of an allergist. If no symptoms occur after you've ingested the predetermined serving size, then it's very unlikely that you're allergic to that food and you can include it in your diet.

So, if you have concerns about food allergy and you have a negative test, please talk about next steps with your allergist. On the flip side, if the history is not very suggestive for food allergy either because somebody has never knowingly eaten a food or experienced a reaction to a food and we have a negative test result, then yes, we should believe those results almost all the time.

i started not feeling well and we couldnt figure out why, long story short we found my GF has mold in the walls of her house, it ruined my clothes and alot of things as I am hypersensitive - she has since sold the house and we have tried to move into another place but she had brought a few things after she agreed to get rid of everything , that is what the doc had said was the only solution .. i have ruined several cpaps and spent several thousand dollars on new cpaps .. she came to stay with me one night and i could tell something she had on was bothering me ,, i used the cpap that night and now everytime I use it i get a headache.. so looks like now I need ANOTHER cpap, has anything else dealt with something like this? its been quite the nightmare to say the least.. at this point i am considering cutting ties because it seems the stuff is everywhere in her car etc and its been affecting my health / wallet, and it seems I am super allergic as it affects me immediatlely.   I have a camper that I put stuff in from her house and now I cant even go inside the camper and we have to sell it, this is unreal and has caused so much stress, anxiety along with not feeling well.

any advice is appreciated.

tx in advance.
