How can I insist on special tests, i.E. Blood tests, tests for food allergies?

How can I insist on special tests, i.E. Blood tests, tests for food allergies?

Offer to pay: Laboratory as well as radiological testing is one of the most expensive things we do in medicine. Insurance companies have contrived to reduce payments to physicians to amounts they paid 20-30 years ago. A medical opinion by a credentialed, board-certified specialist is a bargain. See an allergist. But if you must have that special test for your reassurance offer to pay for it out-of-pocket. ...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

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 more

My blood results came back with food allergies, is it safe to eat those foods if no allergic symptoms occur?

See below: Food allergy is diagnosed by taking a history. Skin testing and/or blood testing is utilized to support the clinical suspicion of food allergy. Skin testing / blood testing should never be done in the absence of a proper history documenting a potential food allergy ( with few exceptions). Based upon the results of one's history and testing, decisions can be made about consuming the food. ...Read more

Can complete blood test diagnosis i have food allergy or other allergy or i do other test for allergy  my complete blood test are normal.

Specific test: Routine blood tests do not include tests for specific food or other allergens. "Shotgun" testing for a bunch of foods without a thorough history to match the results is NOT recommended because there are so many false positive results which could lead to unnecessary avoidance. Allergists are specifically trained and experienced in this matter. ...Read more

Has anyone ever had a blood test to screen for food allergies?

Has anyone ever had a blood test to screen for food allergies?

Not reliable: The gut has its own immune system to suppress immune reactions to foods; you can have a positive ige blood test to foods to which you don't react (false positive). Commonly available igg tests have no correlation with allergic reactions to foods. The best way to diagnose food allergies is to have an allergist take a comprehensive history of food-associated reactions, and do skin tests to confirm. ...Read more

Consultation: Food allergies by blood testing can often lead to false positive results. It is important also to note whether this testing was an ige or and IgG blood test. Tests alone can not be used to managing food allergies and it is imperative to speak to a board certified allergist to present your signs and symptoms in addition to your tests and come up with a plan of management. ...Read more
