I don't know the answer to your question. I did an allergy test at York labs this winter though, and was not thrilled. It took over 2 months to get results back and I've yet to have anyone help with the "one year of free support" of getting answers to my questions.

Let me know if you find somewhere better. I'd like to know. :) Thanks,

Dear Melanie:

Greetings and thank you for your inquiry in to the foodSCAN IgG ELISA


Intolerance Test... the first and most comprehensive food intolerance


which does not require a blood draw!

When it comes to food allergy, there are basically two types:

* Immediate Food Allergy (Classic, Immediate-Onset, IgE-Mediated):


allergic reaction to foods involves the Immunoglobulin E (IgE) antibody


also involves MAST cells. It is the most understood, but least


immune response to foods. It only occurs in less than 2-3% of adults


less than 5% of children. The reaction time occurs anywhere from

seconds to

up to 2 hours and typically affects the skin, airways or the digestive

system. The most commonly known response is anaphylaxis, which can


in death. This type of food allergy is typically tested in a doctor's

office by means of a skin "scratch" test. Additionally, it only takes


single food to cause a reaction and it is typically a food that is



* Hidden Food Allergy (Food Intolerance, Delayed-Onset, IgG-Mediated):


allergic reaction to foods involves the Immunoglobulin G (IgG) antibody


DOES NOT involve MAST cells. It is the lesser understood, but most


immune response to foods. It occurs in anywhere from 45-60% of the


population and affects children and adults equally. The reaction time

occurs anywhere from a couple of hours up to 2-3 days after consumption


the food. Any system, tissue and organ in the body can be affected and

there are over 118 medical conditions/symptoms that are either caused


provoked by this type of allergic response to foods including, but not

limited to, arthritis, weight gain, fatigue, high blood pressure,


Celiac Disease, sinus conditions, asthma and various digestive


Conventional skin "scratch" testing is incapable of detecting this type


food allergy. Even more intriguing is that both a single food and a

combination of foods can cause a reaction and it is usually with foods


are regularly eaten.

Merika, that is odd that you haven't had a good experience with them. Most everyone who has posted on here have said they have been very helpful. I hope it gets better. Were you ok with the results you got?

There is another place that does something similar and charge $525 for the test. I have to think of the name though. I'll let you know. Melanie
