Dietary Antigen Complete

Researchers estimate that at least 60% of the U.S. population suffers from unsuspected food reactions that can cause or complicate health problems. Symptoms can be extraordinarily diverse, ranging from arthritis to eczema to migraines. In extreme cases, food allergies can lead to anaphylactic shock and death if untreated. Fortunately, most people do not have severe reactions.

We can now test 88 foods and look at 4 different pathways that can lead to sensitivities and allergies. This is the most robust food antigen test available! Learn more »

Advanced Oxidative Stress Test

The Advanced Oxidative Stress shows how much oxidative stress there is in the body and how effectively antioxidant enzymes remove it. Reactive oxygen species (ROS, also called free radicals) are produced by virtually every metabolic process in the body and are counterbalanced by the action of antioxidants.

Advanced Intestinal Barrier

Diamine oxidase is an enzyme that breaks down histamine. Histamine is a compound that affects immune response, physiological function of the digestive tract, and acts as a neurotransmitter. Zonulin is a eukaryotic protein structurally similar to Vibrio cholerae’s zonula occludens toxin. It plays an important role in the opening of small intestine tight junctions. Learn more »


Cardiovascular disease (CVD) is the leading cause of death for both men and women, accounting for every 1 in 4 deaths. Certain health conditions, such as diabetes and being overweight, and certain lifestyle choices, such as a poor diet, physical inactivity, smoking, and drinking too much alcohol, increase the risk.

The Complete Cardio Profile with Oxidized LDL offers doctors and patients a more complete picture of a person’s CVD risk compared with a standard lipid profile. This profile measures standard cardiovascular disease markers: total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), very-low-density lipoprotein (VLDL), and triglycerides. In addition, the Complete Cardio Profile measures oxidized LDL, markers of inflammation, obesity, and metabolic syndrome.


Neurotransmitters are brain chemicals which communicate information throughout our body. These include dopamine, serotonin, norepinephrine, epinephrine, and GABA. Neurotransmitters are also major players in brain chemistry. Neurotransmitters help us think and process the world around us. They are critical to our emotional and mental well-being. Imbalances can make us depressed, fatigued, anxious or angry. They can affect our digestion, sleep, memory, and mood patterns. Learn more »
