As an Independent Specialty Lab, G7 Diagnostics understands the complex issues facing healthcare providers today. Our technicians use a multiplex platform. Multiplexing or simultaneously testing each patient sample for all allergens in duplicates, with positive and negative controls, allows for unsurpassed precision and accuracy.



We have all heard people talking about having "allergies" or "sensitivities" as it is quite a common thing in the modern age, but the true definition of what they are and the difference between them is confused or misunderstood. There are two distinct areas of dietary testing we carry out in our laboratory; IgE for allergies and IgG for sensitivities.

The IgE allergic response is the most well-known food allergy reaction. IgE food allergy reactions usually occurs immediately after the ingestion of offending foods, such as nuts or shellfish. The IgE Dietary Panel measures levels of antigen-specific IgE to 91 different foods.

The IgG response to food is actually more common than the IgE response. These hidden food “allergies” are actually food “sensitivities” and are caused by increasing blood levels of IgG antibodies in reaction to specific foods. These food sensitivity reactions are more difficult to notice since they can occur hours or even days after consumption of an offending food and the link between the food and their symptoms may not be connected. The IgG Dietary Panel measures the IgG levels that react to 91 different foods.



Red irritated eyes, constant sneezing, runny nose are common symptoms of environmental inhalant allergies. Typical inhalant allergens are pollen's from grasses, trees and weeds, mold spores, pet dander, and dust mites.

When your body encounters an allergen for the first time, your immune system over-reacts and produces IgE antibodies. The more times you are exposed to an allergen, a chain of reactions occurs in your immune system. The most important of these is the release of a chemical in your body called histamine. Histamine can be present in the nose, sinuses, ears, and throat. It is the production of histamine that produces your allergic symptoms.

G7's IgE Environmental Panel evaluates IgE antibody levels to common pollen's and environmental inhalants. This is an ideal allergy test for patients with suspected environmental and/or seasonal allergies. Specifically, this allergy test evaluates 75 common environmental inhalants specific to geographic regions.

The health of your patient is important to both you and us, as it affects everything we do in life. Receiving your results in a timely manner allows your patient to be active in their community as well as to eat again without worry. Being proactive is about managing their health and choosing the best and most reliable solution for them. Choose G7 Diagnostics.
