The antibodies that provide long term resistance to infections, called Immunoglobulin G (IgG), have a much longer half life than the traditional IgE allergy. Symptoms, ranging from headache and nausea to seizure and hyperactivity, may occur hours or even days after the offending food has been ingested. The degree and severity of symptoms vary because of the genetic makeup of the individual. The complete elimination of IgG positive foods may bring about important improvements in symptoms of irritable bowel syndrome, autism, AD(H)D, cystic fibrosis, rheumatoid arthritis, and epilepsy as demonstrated in numerous clinical studies. The 93 foods tested in the IgG Food Allergy Test increase the identification of numerous offending foods. This test can be performed using either serum from a blood draw or dried blood from a finger prick.
The dried blood spot method is a convenient alternative for patients and practitioners who cannot perform a blood draw. The specimen can be collected from the convenience of home and shipped directly to our laboratory for analysis. We test 93 foods in the IgG dried blood spot test and at the same price as the serum analysis. Other laboratories only offer a limited number of foods tested using dried blood spot at higher prices.
Benefits of Testing
Evaluation of the IgG response to specific foods can provide the physician/patient a tool with which to ease the burden on the already immune compromised host.
The non-evasive and health promoting effects of the treatment is an attractive and affordable option for many patients.
The test results serve to aid the practitioner who is interested in nutritive based therapies adjunct to routine treatment for a variety of conditions.
A growing number of patients seek guidance on food elimination.
IgG-type hypersensitivity can diminish or disappear completely after a few months on the strict diet.
Our experts at the Great Plains Laboratory, Inc. are always available to assist and consult you on the result.
Testimonials
"I believe the Great Plains IgG Food Allergy Test is a phenomenal tool that I have implemented in my practice on a daily basis to help treat patients for a wide variety of symptoms....i.e. headaches, IBS, fatigue, abdominal pain, dermatitis, hair loss, joint pain, acne, thyroid disorders, and vitamin deficiencies. I believe I am a better physician due to this testing transforming my ability to properly diagnosis and treat patients effectively."

"By just following the results the food allergy test, where only low level of reactivity was reported in wheat and sugar, I just minimized these two elements from the environment under the supervision of our food nutritionist in Pakistan and within 15 days I have witnessed that my son has started to sit calmly for short noticeable time spans and his impatient violent movements also started to appear to have slightly eased out. Even this change has also been acknowledged by the special school.
After the receipt of Gluten / Casein Peptide test report we plan to initiate comprehensive follow-up in the light of other reports with the help of our nutritionist and I am sure that the little progress signs witnessed in my son are quite encouraging and my son will soon be a part of normal life. Any parents of an ADHD / Autistic child in Pakistan can get in touch with me to have first hand feel of my personal experience through my cell No 0092-300-8414169."

"We did the IgE and IgG food allergy testing on our son last August and the tests came back positive to 55 allergies combined! Some of them were very, very high. We have done our best to keep him free of the higher allergens and he is so improved now.
None of the doctors ever suggested that we try food allergy testing. They all admitted that we were dealing with a neurological problem and it was bad but nobody wanted to find out WHY!! I thank God that I didn't give up searching for answers and that I was led to your web site and so much information.
We are thankful that we now have a mostly happy 4 year old who is enjoying his life so much more. We are so thankful to all of you at the lab, you are all doing such a worthwhile work!!!!!!!"

“I just want to express my sincerest gratitude for your research and commitment to helping people. If it were not for your work, I honestly believe that my son would not be talking, socializing nor making the remarkable progress that he has been making in the past five months since starting the GFCF diet.”
