Let's say you tested negative for a food allergy on both the IgG and IgE tests. What is the likelihood that you are actually allergic to the item?

Let's say you tested negative for a food allergy on both the IgG and IgE tests. What is the likelihood that you are actually allergic to the item?

Depends: Having igg to a food merely means that you have been exposed to that food and in fact the igg4 (a subclass of igg) may even indicate that you can tolerate that food. The presence of ige to a food alone does not necessarily mean that you are allergic to it. Usually it takes a much higher value above the normal to get a positive response when challenged. ...Read more

Allergies (Definition)

Essentially allergies occur when your immune system goes crazy and decides to has to fight against things it should be ignoring. The immune system of people without allergies simply ignores the pollen in the air or the dander on their cat while an allergic person's immune system creates cells to fight against the pollen or dander. The allergic reaction causes the ...Read more

Avoidance, the only: treatment if that's a true allergy to egg/dairy products, which is kind of rare to start at your age, I'm not sure what exactly is your question, but the high IgE can be irrelevant in food allergy, clear history is the most important parameter, other tests kind of confirm the diagnosis, at any rate keep avoiding eggs and dairy as much as you can, I'm happy to c u if u wish book thru vezeeta 16676 ...Read more

Is food allergy can be treated through immunotherapy or anti IgE therapy ?

Is food allergy can be treated through immunotherapy or anti IgE therapy  ?

No: It is not recommended to use immunotherapy for treatment of food allergy. There are studies being done to try to desensitize by giving small amounts of the food frequently but these are still in a research phase. Anti-ige treatment with omulazimab is approve for asthma treatment in the us and it will often make the patient less reactive to foods they are allergic to. ...Read more

Can a food allergy cause mental slowness/confusion? I have new food allergies (IgE testing) and trying to make sense of it all. Thanks!

Not likely: Many people with no food allergy will produce antibody that reacts to the food allergy panel. Thus, these tests need to be interpreted by experts who treat food allergy daily. Skin testing is often more accurate, but ones history of symptoms that follow an ingestion is critical as well. Yes, dizziness/fogginess can occur with allergy, but is transient immediately following intake. Be well! ...Read more

Different types: There are actually 5 (and probably more) antibody responses to infection or allergens: igg, igm, iga, igd, and ige. Our IgM and igg antibodies are usually produced in response to infection; ige antibodies usually produced in response to allergic reactions. ...Read more

I recently had a Ige Blood Test for food allergies. The results can back at tomatoes: moderate Wheat: Low and Soy: Low. What does this mean?

Complicated: You cannot draw your conclusions from your testing only. If you have a positive test but eat the food every day without symptoms you are not allergic to that food. On the other hand if you have a low positive test but get hives every time you eat it you are allergic. The correct diagnosis is made by a combination of history and test results. You may need a supervised food challenge. ...Read more

Are blood tests for allergy/IgE levels to foods considered reliable? Paranoid over certain foods and want to put fears to rest and liberalize my diet.

Are blood tests for allergy/IgE levels to foods considered reliable? Paranoid over certain foods and want to put fears to rest and liberalize my diet.

False positives: If the result of either the Allergy skin test or specific IgE test is negative then it's very reliable. Positive results on the other hand are only accurate 40-60% of the time so would need to be matched with specific allergy symptoms upon eating the food in question. Screening for a bunch of foods without a thorough history is therefore frowned upon. Testing for Celiac somewhat different. ...Read more
