Hello Lisa, Thank you for asking at HCM. There are two types of allergy tests - skin prick test (which you have been undergone) and serum tests (ImmunoCAP or RAST). I suggest you not to be worried by test results. These tests are not 100%. They only complement a clinician s decision about diagnosis of your food allergy. If you are dermographic, skin testing will give you what we call false positives (means even if test is positive you are not allergic to it). So in a dermographic person, skin testing is not a reliable test. So forget the results of skin test if you are dermographic!! Diagnosis of food allergy requires a very detailed history about your symptoms & your diet, right from very beginning when you had your first allergy symptoms. This requires a detailed consultation. After suspecting the foods you may be allergic to, you may be advised serum allergy tests to support the diagnosis. The best diagnosis of food allergy is by food challenge which is done at specialized allergy centers. I would suggest you to keep a food diary in which you can keep note of food taken (including ingredients) and every symptoms you developed, with time & date. This will help you and your doctor to suspect what is it that may be causing symptoms. Common food allergies are milk, wheat, peanut, tree nuts, soy, eggs, fish & shellfish. But one can be allergic to any other food substances from routine diet. Also, I should tell you that there are other gastrointestinal disorders which may mimic food allergy and there is food intolerance (in simple words it means one cannot tolerate some foods) also. A gastroenterologist consultation would be helpful to you if you don t have food allergy. So I would suggest you not to think that you are allergic to all foods! Also I would suggest you to take an antihistamine (levocetirizine or cetirizine or fexofenadine) and montelukast daily to control your symptoms. Wish you best of the health. Regards.
