Food IgG Test – For Food Sensitivity
Food sensitivities generally involve a number of antibodies (aka. immunoglobulins), but the most prevalent one is called IgG. There are 4 different types of IgG – 1 thru 4. Each plays a different role in the immune system, but as a group they are useful to test against various foods to determine immune intolerance. When elevated they point to a problem that the immune system is hypersensitive and excess Total IgG levels can trigger inflammation throughout the body. Many people with Food IgG sensitivities complain of fatigue, headaches, sinus congestion, digestive problems such as pain, bloating, gas and bowel changes, as well as joint pain and stiffness. Therefore, the Food IgG Test is extremely useful for anyone looking to improve their overall health.
Food IgG is also correlated with a variety of mental health challenges, and elevated Total IgG is often seen positively correlated to depression, anxiety, autism, mood disorders and others. Many children on the autism-spectrum have elevated Total IgG to gluten, casein, corn and soy which correlates to behavior issues, sleeping problems and poor attention.
There are many tests on the market that use the IgG4 as their determining antibody for immune reactivity. However, this antibody is an incorrect marker to use solely as its elevation can indicate immune tolerance and actually has a blocking effect against food sensitivity. Therefore, the more accurate test to perform is Total IgG which is what the Food IgG Test from Great Plains Laboratory uses. This test is available as a finger prick analysis which makes it extremely easy to do at home, and bypasses the need to do blood testing which is problematic for some children. The Food IgG Test analyzes over 90+ foods and is highly accurate for immune sensitivities. The Food IgG Test from Great Plains is considered to be a foundational test to perform along with other metabolic tests such as the Organic Acid Test.
