The GI Effects Comprehensive Stool Profile can reveal important information about the root cause of many common gastrointestinal symptoms such as gas, bloating, indigestion, abdominal pain, diarrhea, and constipation. This stool analysis utilizes biomarkers such as Calprotectin to differentiate between Inflammatory Bowel Disease (IBD) and Irritable Bowel Syndrome. In addition, the GI Effects test can be used to evaluate patients with a clinical history that suggests a gastrointestinal infection or dysbiosis.

The IgE Food Antibody Assessment is a blood test that measures IgE antibodies to 19 of the most allergenic foods. The panel also includes a total IgE measurement. The body can react to foods in many different ways. The prevalence of food allergies in Western countries is rising, with up to 10% of the population affected. This trend likely involves a complex interplay between genetic, epigenetic, and environmental risk factors.1 Testing for IgE food antibodies is useful for individuals who suspect that a food is responsible for causing their symptoms. The presence of circulating antibodies may affect each patient differently. According to the American Academy of Allergy, Asthma, and Immunology, “A key message is that a positive allergy test result (skin or blood) indicates only the presence of allergen-specific IgE (called sensitization). It does not necessarily mean clinical allergy (i.e., allergic symptoms with exposure).”2 Therefore, test results should always be viewed in the context of the overall clinical picture.

Food allergies and sensitivities are recognized to be correlated with many plaguing health conditions, but with proper identification and elimination of offending foods, many experience relief from their symptoms.

Our 144 Food Panel is a comprehensive food sensitivity testing option for patients who may have underlying sensitivities to less conspicuous antigens. Assess IgG, IgG4, or IgA antibody reactivity across a broad range of culturally-diverse foods to help identify trigger foods in these individuals.

Our super panel is a quantitative ELISA analysis of specific IgG, IgG4, and IgA antibodies to 144 common foods and spices.

When food particles enter the bloodstream, your immune system can sometimes identify these food proteins as ‘foreign’ and produces IgG antibodies to ‘attack’ the particular food in question. 

This response is your immune system’s natural defense mechanism to ward off harmful invaders in the body which can create inflammation. This inflammation can then trigger troublesome symptoms, which may persist if they are neglected.

Suffering from IBS, headaches, bloating, tiredness? These are often signs of a food sensitivity or a food intolerance affecting your daily life. The YorkTest Premium Food Sensitivity Test analyzes IgG reactions to over 200 food and drink ingredients.

Oxidative Stress Analysis 2.0 is a nutritional test used to evaluate the body’s oxidative stress status. Normal human metabolism produces highly reactive molecules known as free radicals, typically controlled by antioxidants. When the production of free radicals becomes excessive, the antioxidant mechanisms of the cell become overwhelmed, resulting in oxidative damage. The Oxidative Stress 2.0 (Urine) uses a simple urine test to evaluate two key biomarkers of oxidative stress damage.

This non-invasive test requires a single first morning void (FMV) urine collection. Detailed Information Urinary 8-hydroxy-2′-deoxyguanosine (8-OHdG) is an excellent biomarker of oxidative stress and a risk factor for a variety of diseases, including cancer. Reactive oxygen species (ROS) are produced as a result of normal oxygen metabolism or exposure to xenobiotics. Excessive levels are associated with oxidative damage to lipids, proteins and DNA. ROS-induced damage to nuclear and mitochondrial DNA occurs readily at the guanosine bases that are removed by DNA repair mechanisms and excreted in urine.

SIBO Profiles are non-invasive breath tests which capture exhaled hydrogen (H2) and methane (CH4) gases following patient ingestion of a lactulose solution to evaluate bacterial overgrowth of the
small intestine.

Clinicians have the option of a 2 or 3-hour SIBO assessment.
The 3-hour SIBO profile provides insight into gas levels over a longer period of time, and is recommended for patients with slower gastrointestinal transit or constipation.

Essential Estrogens™ is a targeted urinary hormone test designed to evaluate estrogen metabolism specifically. This hormone test offers clinical insight into parent estrogens, key estrogen metabolites, and relevant ratios and is useful for initial estrogen assessment as well as follow-up testing to monitor response to therapies and/or to check levels of previously abnormal results.

The DUTCH Plus® takes hormone testing to a whole new level. In addition to sex hormones and their metabolites, the DUTCH CompleteTM looks at the overall diurnal pattern of free cortisol, and the total and distribution of cortisol metabolites. The DUTCH Plus® adds the Cortisol Awakening Response (CAR) to bring another important piece of the HPA-axis into focus.

This profile tests the adrenal hormones DHEA-S and diurnal cortisol. When individuals experience continuous stress, not only from emotional stressors (e.g., marital, financial, and occupational) but also from physical stressors (e.g., sleep deprivation, caffeine consumption, pain, extreme exercise), it can lead to changes in adrenal hormone levels, related to disorders ranging from anxiety to infertility.

The Adrenocortex Stress Profile (ASP) provides an assessment of the Hypothalamic-Pituitary-Adrenal (HPA) axis using carefully timed salivary samples of the hormones cortisol and DHEA. Salivary testing is an easy, non-invasive option to measure unbound, biologically active parent hormone levels.

We are all exposed to different amounts of essential and toxic elements depending on where we live, our diet and supplementation routine, and the environmental pollution of the air we breathe. Essential elements are only conducive to optimal health when they are within optimal ranges – levels that are too low or too high can have detrimental effects on health – and exposure to toxic heavy metals has multiple adverse health effects. The Comprehensive Toxic and Essential Elements Profile allows a complete assessment of the most important elements implicated in health-related effects, as it includes a measure of both short and long term exposure to all 4 of the most toxic environmental heavy metals, as well as highlighting nutritional element deficiencies earlier than a typical serum test. The Comprehensive Toxic & Essential Elements Profile assesses an individual’s levels of the essential nutrients iodine, selenium, zinc, copper, magnesium, lithium, and bromine, and their exposure to the toxic elements arsenic, cadmium, and mercury.

Urine Elements are traditionally used to evaluate exposure to potentially toxic elements and wasting of nutrient elements. Additionally, the comparison of urine element concentrations before and after administration of a chelator can be used to estimate net retention of potentially toxic elements. Subsequent urine element analyses, also following the administration of a chelator, are useful for monitoring the efficacy of metal detoxification therapy. Results are expressed per 24 hours or creatinine corrected to account for urine dilution effects.

The COVID-19 Immune Response Panel measures both nucleocapsid (N-protein) and S-RBD antibodies. N-protein antibodies do not rise in response to COVID-19 S-RBD vaccinations. The combined serum IgM/IgG tests measure the body’s response to COVID-19 nucleocapsid (N) and spike protein receptor-binding domain (S-RBD) exposure. The N and S-RBD antibodies’ combination assay has a > 99% positive and negative predictive value 15 days after COVID-19 exposure. This test does not differentiate between IgM and IgG; studies indicate that joint testing is as or more reliable than individual IgM and IgG testing in confirming COVID-19 exposure.

Spectracell’s Micronutrient Test (MNT) will tell you exactly the micronutrients in which a patient is deficient. It evaluates how 31 different vitamins, minerals, amino acids, and antioxidants are working within a person’s cells. But it goes even further—The MNT will tell how well cells can withstand oxidative stress, how well cells are metabolizing carbohydrates and how adeptly cells function when launching an immune response.

Armed with this information, you can develop a targeted supplementation regimen based on the results. Your patients’ repletion plan will be unique to their personal biochemistry at this point in their life. Once cellular deficiencies are corrected, symptoms improve and patients often experience systemic benefit.

The one-size-fits-all approach to clinical nutrition is an outdated model. Find out exactly what your patients need.
