Melanie 0 Posted February 10, 2005 Report This Post (To report rule violations to admin) Share Posted February 10, 2005 So I'm having bad symptoms again and have decided I have to have some sort of test done even though I can't afford it at all. I think I will go with York labs but I'm wondering about them using IgG rather than IgA or IgE, which are more common in the GI. Has anyone read anything about this? Link to post Share on other sites
Merika 0 Posted February 12, 2005 Report This Post (To report rule violations to admin) Share Posted February 12, 2005 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, Merika Link to post Share on other sites
Melanie 0 Posted February 12, 2005 Author Report This Post (To report rule violations to admin) Share Posted February 12, 2005 Here is what York labs said: From: "York Nutritional Laboratories, Inc." <info@yorkallergyusa.com> Add to Address Book To: "'Melanie'" <fairybug02@yahoo.com> Subject: RE: IgG vs IgE and IgA Date: Fri, 11 Feb 2005 17:00:34 -0500 "York Nutritional Laboratories; Uses the well-regarded ELISA test." - The Wall Street Journal, Friday, October 26, 2001 - Dear Melanie: Greetings and thank you for your inquiry in to the foodSCAN IgG ELISA Food Intolerance Test... the first and most comprehensive food intolerance test 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): This allergic reaction to foods involves the Immunoglobulin E (IgE) antibody and also involves MAST cells. It is the most understood, but least occurring immune response to foods. It only occurs in less than 2-3% of adults and 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 result 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 a single food to cause a reaction and it is typically a food that is rarely eaten. * Hidden Food Allergy (Food Intolerance, Delayed-Onset, IgG-Mediated): This allergic reaction to foods involves the Immunoglobulin G (IgG) antibody and DOES NOT involve MAST cells. It is the lesser understood, but most common immune response to foods. It occurs in anywhere from 45-60% of the general population and affects children and adults equally. The reaction time occurs anywhere from a couple of hours up to 2-3 days after consumption of 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 and/or provoked by this type of allergic response to foods including, but not limited to, arthritis, weight gain, fatigue, high blood pressure, arthritis, Celiac Disease, sinus conditions, asthma and various digestive disorders. Conventional skin "scratch" testing is incapable of detecting this type of 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 that 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 0 Posted February 12, 2005 Author Report This Post (To report rule violations to admin) Share Posted February 12, 2005 Ok, it is Great Smokie Labs: http://www.gsdl.com/home/assessments/finds...immunology.html They were recommended by a lady with Celiac here. It took her a while to get dxed and they sent her blood samples there. Link to post Share on other sites
