Yes: Patch testing can detect certain types of food allergies. For anaphylactic type (ige mediuated) food allergies, standard skin prick testing or specific ige blood tests are better at identifying food allergies. For other non-ige mediated reactions such as eosinophilic esophagitis, patch testing can identify some additional food sensitivities. Only have test recommended by a trained md. ...Read more

However, dermatitis herpetiformis is frequently linked to gluten sensitivity. ...Read more
Avoidance &challenge: Every test out there is imperfect. This is because there are many different mechanisms of food sensitivities- some mediated by igg, e, a & m antibodies, some by lymphocytes, some by inability to digest (lactose), some by inability to metabolize (nightshades) and there aren't tests for all of these. Avoiding suspect foods for 5 days to 1 month & challenging to see if you react is still the best test! ...Read more
What are common symptoms of allergy or intolerance to wheat (not celiac disease)? How is allergy/intol determined - thru testing or elimination diet?
Intolerance/immune: Intolerance consists of any undesired effects from from wheat and there is no definite test for it (other than a double-blind food challenge). Allergy to wheat often affects the guts but may cause hives, swelling, nasal congestion, and even rarely anaphylaxis. Allergy can be detected by skin testing or allergy blood test but double-blind food challenge remains the gold standard. ...Read more

Can you explain the differences between celiac disease, gluten intolerance, and wheat or gluten allergy?
Neither: No allergy antibodies in food intolerance. That's what we're looking for with blood and skin testing. So testing can rule-out food allergy in a case of food intolerance. The history and physical examination is usually sufficient to make a diagnosis of food intolerance. If testing is recommended skin testing is much less expensive and perhaps a little more sensitive than blood testing. ...Read more

Maybe: The heart often reacts to whats going on around it. While its not the primary problem the heart can go fast when the body is stressed. This is called reactive tachycardia. A holter (if symptoms are frequent) or a 30 day event recorder ( if only happening a few times a week or month) would be helpful. Blood work along with a complete physical and possibly an echo of heart would also be part of work. ...Read more
Yes and not really: Food allergy is diagnosed by assessing the history (in the context of symptoms), and either allergy skin test or specific ige blood test. These are especially helpful in confirming a patient does not have food allergy if test is negative. Sometimes a food challenge is performed to really assess if the food allergy is present. Lactose intolerance can be diagnosed with a breath hydrogen test. ...Read more
