Tannin Allergy Test
Yes: Skin allergy testing can check for number of allergens. These include environmental and food allergens. ...Read more
Allergies occur when your immune system is triggered by envirionmental factors it should ignore--for example, pollen in the air, or dander on a cat or dog--and creates cells to fight against them. An allergic reaction typically causes itching, congestion, or drainage, and ...Read more
No: Appropriate allergy testing is guided by the patients history and physical examination. Based upon this one's allergist will make a decision what to be tested for. The test, particularly for outdoor allergens is based upon the common allergens is that particular agricultural zone. Does this mean that all allergens will be tested no. ...Read more
Easy: Skin testing for pollen allergy entails: cleaning the skin with alcohol, number the skin to keep track of the different allergens tested, a "prick" with skin test device that has a drop of the allergen on the tip and then waiting 15-20 minutes to see if a reaction occurs. The skin test feels like a mosquito bite it is really quite painless. ...Read more
Can environmental allergies (food, pollen, dust mites, contrast dye, penicillin) cause a high positive ANA?
I have seen this: While the +ANA is suggestive of SLE there can be other causes - other connective tissue disease, autoimmune thyroid disease, auto immune hepatitis to name some. I have seen a lot of people with + ANAs who only have as another problem a history of allergic reactions and I am convinced that thee allergic reactions can cause a + ANA. Everyone can have very low titters (amount) of ANA. ...Read more
Nearly everything: Immunocap ige is the most commonly employed method to test allergy after allergy skin testing. It can be tested to nearly all allergens available. Blood test for allergy is meaningful when strongly positive but has a high false-negative rate when compared to allergy skin testing. The allergens used in the blood testing are often different from those used in allergy skin testing. ...Read more
Does desensitization vaccination works for allergic asthma?I got positive skin prick tests for 4-5 allergens....
Yes: It is effective about 80% of the time. However I'd doubt that getting allergy shots for 4-5 allergens would work for you since most people are allergic to dozens of airborne allergens except in the case of occupational exposure. ...Read more
Wallnut allergy: Not that i know of. A skin patch test by dermatologist or allergist is routine. ...Read more
Is an IGE allergy blood test as accurate as a skin test? My skin test from 1 year prior to IGE blood test showed additional allergens.
Likely complementary: Although prick skin test is considered better in detecting food allergies the results of blood tests are complementary. I often order the blood test first in a case of a food suspected of causing anaphylaxis. If the result is negative or equivocal, then I would proceed with a skin test prior to a food challenge. The results are at times discrepant. ...Read more
Flushing reaction after eating foods,no commonality yet,throat weird.Mastocytosis negative,blood allergy test neg, food allergy on back neg.What is it?
Postive, high, rast test results - only hayfever and animal reactions though? Are rast tests reliable?
RAST vs skin tests: The reason allergists prefer skin tests to rast tests is because the skin tests show your body's biological response to allergens. Rast tests only measure the amount of antibody and do not predict its clinical binding and symptom-provoking abilities. That said, no test is perfect. All have to be compared to your experience and correlated with your history. Allergists spend more time doing this. ...Read more
If food allergy prick test is negative (mild redness) and blood rast test negative is it mean you are not allergic to foods?So y get reaction to foods
Not 100%: If both tests are negative, the chance of being allergic to that food is very very small. However when the history of a food allergy is strong, and the tests were negative, i often ask the patient to bring in the fresh food for the testing instead of relying on commercial food extracts. If the person is still quite concerned over it a challenge test can be done at the office. ...Read moreSee 1 more doctor answer
Nothing is perfect: No test is 100% reliable - neither skin testing nor blood testing. That's why allergists try to order relevant tests selected based on a comprehensive medical history and physical examination. The results must be interpreted & used as clues to a solution. They're not an answer in themselves. I'm frequently called by doctors who order allergy tests & then want me interpret them over the phone. ...Read moreSee 2 more doctor answers
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
I am an eczema patient should I go for ALLERGY ECZEMA COMPREHENSIVE PANEL, SERUM (FEIA) or ALLERGY COMPREHENSIVE PROFILE, SERUM
None of these: Eczema---atopic dermatitis----is NOT an allergy. Allergy tests are not useful, often harmful, for eczema. It is not related to foods. Not "stress" either. It is a genetic defect in the surface of the skin. We have very good technology to help eczema, but no cure. SEE A DERMATOLOGIST. Meanwhile use skin cleansers with pH 6 to 7. Apply a liberal amount of a ceramide cream after washing. A prescripti ...Read more
Probably skin.: If someone is allergic to some allergen, like milk, a skin test can be done to see if there is reaction to it. Swelling and redness of the site can tell how severe it is. Clinical labs may be able to test reactions serologically, so blood might be taken also for this. ...Read moreSee 1 more doctor answer
Allergy RAST/blood (IgE) test reports no milk allergy. Is it possible I could still be allergic to dairy? Suffering from thick nasal mucus.
Yes: Either RAST (replaced by ImmunoCap IgE) and prick skin testing can miss some food allergies. I often test a patient to the food itself when the history and test findings do not match. Recently I was about to challenge a young boy to walnut (history positive, skin test negative) when the skin test turned out to be highly positive to the actual nut. Mold & mite allergies are more likely in HK. ...Read more
