T + B-Lymphocyte Differential

The "T + B-Lymphocyte Differential" panel by Labcorp is a comprehensive test that involves flow cytometry methodology to evaluate different subsets of lymphocytes in the blood. This test includes the analysis of various lymphocyte types such as T cells (CD3+), B cells (CD19+), and natural killer (NK) cells (CD3^{-}CD56+). It provides detailed measurements like the percentage and absolute counts of these cells, as well as the CD4:CD8 ratio, which is crucial in assessing immune system health. Specifically, the test measures the percentages and absolute counts of CD3+ T cells, CD3+CD4+ helper/inducer cells, CD3+CD8+ suppressor/cytotoxic cells, CD19+ B cells, and CD3^{-}CD56+ NK cells. Additionally, it includes a complete blood count (CBC) with differential and platelet count. This panel is particularly useful in the classification and diagnosis of primary immunodeficiency diseases and in monitoring patients with AIDS. The test requires a whole blood specimen, collected in specific types of tubes, and it's important that the specimen is handled correctly to maintain its viability.

The use of PCR testing allows US BioTek to more precisely identify even the smallest amounts of markers within the stool providing accurate, reliable, and reproducible results. ELISA An established immunological technique, ELISA is widely used to detect the presence of specific antibodies or antigens in a patient’s blood.

The Lymphocyte MAP

Comprehensive Lymphocyte Immunophenotyping: A Breakthrough in Immune System Analysis FEATURES Unique Immunotypes for Comprehensive Insights The panel includes 14 immunotypes designed to uncover critical immune system trends by analyzing a wide range of determinants. Advanced Th1/Th2 Balance Analysis (Immunotypes 6 & 7) Utilizes the proprietary Cyrex Fluorescence-Activated Cell Test (Cyrex FACT™) to assess T-helper-1 (Th1) and T-helper-2 (Th2) dominance. Unlike traditional methods that measure cytokine levels, Cyrex FACT™ analyzes specific CD markers on the surface of Th1 and Th2 cells, offering a more precise and actionable insight into immune balance. Regulatory T Cells (Tregs, Immunotype 8) Evaluates Tregs, essential for maintaining the balance between Th1 and Th2 responses. Low Treg levels can contribute to issues such as immune suppression, autoimmune disorders, increased infections, and cancer.

Thyroid Panel

A Thyroid Panel is an essential health category for assessing thyroid function, a key aspect of metabolic health and well-being. This panel typically includes tests for Thyroid Stimulating Hormone (TSH), Free Thyroxine (T4), Free Triiodothyronine (T3), and sometimes Thyroid Peroxidase Antibodies (TPO Antibodies), providing a comprehensive view of thyroid health. The thyroid gland, located in the neck, plays a crucial role in regulating metabolism, energy levels, and body temperature. Abnormalities in thyroid function can lead to conditions such as hypothyroidism (underactive thyroid) or hyperthyroidism (overactive thyroid), each with distinct symptoms and health implications. Hypothyroidism can cause fatigue, weight gain, and depression, while hyperthyroidism may lead to weight loss, anxiety, and heart palpitations. The Thyroid Panel is vital for diagnosing these conditions and is especially important for individuals experiencing symptoms of thyroid dysfunction, pregnant women, or those with a family history of thyroid disorders.

Tickborne Diseases 2.0

Tickborne Diseases 2.0 – Comprehensive Molecular & Serologic Panel by Vibrant Wellness Advanced testing for Lyme disease and other clinically relevant tickborne infections in the United States Tickborne diseases (TBDs) are among the fastest-growing vector-borne infections in the U.S., driven by expanding tick habitats and increased human exposure. The Tickborne Diseases 2.0 panel by Vibrant Wellness is a comprehensive, multi-pathogen test designed to improve detection of Lyme disease and other tick-associated infections using advanced serologic methodologies. This panel is structured to support clinicians in evaluating patients with acute, chronic, or unexplained inflammatory, neurologic, or multisystem symptoms where tick exposure is suspected. Why Tickborne Diseases Are Clinically Challenging Ticks can transmit pathogens after approximately 24–72 hours of attachment, depending on the organism and tick species.

Total Immunoglobulins

The Total Immunoglobulins panel measures four major antibody classes—IgG, IgA, IgM, and IgE—to provide a comprehensive overview of immune system activity and balance. These antibodies play distinct but complementary roles in infection defense, immune memory, mucosal protection, and allergic responses. Evaluating immunoglobulin levels helps identify immune deficiencies, chronic or recurrent infections, autoimmune conditions, allergic disease, and abnormal immune activation. This panel is particularly useful for individuals experiencing frequent infections, unexplained inflammation, allergy-related symptoms, or those undergoing immunosuppressive or immune-modulating therapies. IgG (Immunoglobulin G) What it measures IgG is the most abundant antibody in the bloodstream and is central to long-term immune protection. It is produced after initial exposure to an infection and remains in circulation to provide immune memory and lasting defense.

Total Tox-Burden

The Total Tox Burden panel is a comprehensive test that screens for three major categories of toxins that can affect health: environmental toxins, mycotoxins (mold toxins), and heavy metals. By combining these into one test, it gives a broader picture of your body’s toxic load. What’s Included Mycotoxins: Detects 31 mold toxins that can come from water-damaged buildings, contaminated food, or environmental exposure. Mycotoxins can affect the immune system, energy levels, and overall health. Heavy Metals: Screens for 20 common heavy metals such as mercury, lead, and arsenic. These metals can accumulate in the body over time and may contribute to fatigue, cognitive changes, or organ stress. This test can be done with or without a provocation method. Environmental Toxins: Looks for chemicals from plastics, pesticides, and industrial pollutants that are often encountered in daily life. These toxins may disrupt hormones, metabolism, and cellular health. Why This Test Matters Everyday exposures—from food and water to household products and the environment—can build up in the body.

Toxic & Essential Elements (Hair)

Hair is an excretory tissue for essential, nonessential and potentially toxic elements. In general, the amount of an element that is irreversibly incorporated into growing hair is proportional to the level of the element in other body tissues. Therefore, hair elements analysis provides an indirect screening test for physiological excess, deficiency or maldistribution of elements in the body. Clinical research indicates that hair levels of specific elements, particularly potentially toxic elements such as cadmium, mercury, lead and arsenic, are highly correlated with pathological disorders. For such elements, levels in hair may be more indicative of body stores than the levels in blood and urine. All screening tests have limitations that must be taken into consideration. The correlation between hair element levels and physiological disorders is determined by numerous factors. Individual variability and compensatory mechanisms are major factors that affect the relationship between the distribution of elements in hair and symptoms and pathological conditions.

Toxic & Essential Elements (Whole Blood)

Blood elemental analysis should be performed prior to the initiation of, and intermittently during, metal detoxification. Toxic metals disrupt essential element metabolism and are antagonistic to some elements such as cadmium to zinc and lead to calcium. Further, commonly utilized metal detoxification agents can cause significantly increased urinary wasting of some essential elements. Analysis of toxic elements/metals in whole blood is useful for assessment of recent or ongoing exposure to the toxins, but does not provide accurate information about net retention of toxic metals in the body. For example, blood lead levels peak about five hours after acute exposure and then decrease exponentially with a half-life in blood of about one month. Evaluation and elimination of ongoing exposure to toxic metals is another important component of efficient metal detoxification. Accurate assessment of essential element status in the most appropriate compartment is highly recommended for determination of appropriate supplementation.

Toxic Element Exposure Profile; Hair (Doctor's Data)

Hair Elements analysis provides information regarding recent and ongoing exposure to potentially toxic metals, especially methylmercury and arsenic, and time-averaged status of specific nutrient elements. This noninvasive screening test requires only .25 grams of hair. Doctor's Data offers a Hair Elements profile containing essential and toxic elements and a Hair Toxic Element Exposure profile containing an expanded lineup of toxic metals. Useful for: Toxic Element Exposure Excessive Fish Consumption Alopecia Depression Fatigue Malabsorption Hypertension Impaired Glucose Tolerance Kidney Function Parkinson's-like Symptoms Sexual Impotence or Decreased Testosterone Production Vision Problems -------------------- With respect to its contained elements, hair is essentially an excretory tissue rather than a functional tissue. Hair element analysis provides important information which, in conjunction with symptoms and other laboratory values, can assist the physician with an early diagnosis of physiological disorders associated with aberrations in essential and toxic element metabolism.

Toxic Metals (Stool)

Fecal elemental analysis provides a direct indication of dietary exposure to toxic metals and indirect information about the potential for toxic metal burden. Chronic, low-level assimilation of toxic metals can result in accumulation in the body. For many toxic metals, fecal (biliary) excretion is the primary natural route of elimination from the body. Specimen collection is convenient for the patient and only requires a single-step procedure. Elements are measured by ICP-MS and expressed on a dry weight basis to eliminate variability related to water content of the specimen.

Toxic Metals (Urine)

Analysis of the levels of toxic metals in urine after the administration of a metal detoxification agent is an objective way to evaluate the accumulation of toxic metals. Acute metal poisoning is rare. More common, however, is a chronic, low-level exposure to toxic metals that can result in significant retention in the body that can be associated with a vast array of adverse health effects and chronic disease. One cannot draw valid conclusions about adverse health effects of metals without assessing net retention. For an individual, toxicity occurs when net retention exceeds physiological tolerance. Net retention is determined by the difference between the rates of assimilation and excretion of metals. To evaluate net retention, one compares the levels of metals in urine before and after the administration of a pharmaceutical metal detoxification agent such as EDTA, DMSA or DMPS.

Toxic Metals; stool

If you're concerned about the possibility of heavy metal accumulation in your body, the Toxic Metals Panel Fecal Test measures fecal levels of antimony, arsenic, beryllium, bismuth, cadmium, copper, lead, mercury, nickel, platinum, thallium, tungsten and uranium. If you're concerned about the possibility of heavy metal accumulation in your body, this Toxic Metals Panel is an important step to measure the following analytes: Antimony, Arsenic, Beryllium, Bismuth, Cadmium, Cesium, Copper, Gadolinium, Lead, Manganese, Mercury (best for dental amalgam exposure), Nickel, Platinum, Thallium, Tungsten, Uranium Analysis of elements in feces provides a means to assess oral exposure, and to a lesser extent endogenous detoxification of potentially toxic metals. For several toxic elements such as mercury, cadmium, lead, antimony and uranium, biliary excretion of metals into feces is a primary natural route of elimination from the body. Studies performed at Doctor’s Data demonstrate that the fecal mercury content and number of amalgam surfaces are highly correlated.

Toxic Non-Metal Chemical Profile

Every day, we are exposed to hundreds of toxic chemicals through products like pharmaceuticals, pesticides, packaged foods, household products, and environmental pollution. As we have become more exposed to chemical-laden products and to toxic chemicals in food, air, and water, we have been confronted with an accelerating rate of chronic illnesses like cancer, heart disease, chronic fatigue syndrome, chemical sensitivity, autism spectrum disorders, ADD/AD(H)D, autoimmune disorders, Parkinson’s disease, and Alzheimer’s disease. Because exposure to environmental pollutants has been linked to many chronic diseases, The Great Plains Laboratory has created GPL-TOX, a toxic non-metal chemical profile that screens for the presence of 172 different toxic chemicals including organophosphate pesticides, phthalates, benzene, xylene, vinyl chloride, pyrethroid insecticides, acrylamide, perchlorate, diphenyl phosphate, ethylene oxide, acrylonitrile, and more. This profile also includes Tiglylglycine (TG), a marker for mitochondrial disorders resulting from mutations of mitochondrial DNA.

Tree Nut Allergen Panel

The Tree Nut Allergy Test Panel measures the levels of specific IgE antibodies in your blood to specific peanut and tree nut allergens. This panel measures responses to almond, Brazil nut, cashew nut, hazelnut, macadamia nut, peanut, pecan nut, pistachio, and walnut. This test reports the presence of lgE(s) antibodies to peanut and tree nut allergens, but the result by itself cannot confirm the presence of the allergy.

Tuberculosis Testing

What is tuberculosis (TB)? Tuberculosis, or TB, is an infectious disease caused by the bacterium Mycobacterium tuberculosis. Tuberculosis was once the leading cause of death in the United States, but it can now be successfully treated if discovered in time. Microscopic droplets suspended in the air pass the TB organism from person to person. Infection can occur when an uninfected person comes in contact with someone who has active tuberculosis. People who are exposed to TB may never get sick. They develop what is called latent TB infection. A person with latent TB is not contagious and does not show any signs or symptoms of being sick. The immune system controls the infection. Latent TB may develop into active TB if the immune system becomes weakened. A person with active TB disease is sick and shows signs and symptoms of the disease (e.g., persistent cough, weight loss). People with active TB are infectious and can spread the TB bacterium to others. How can I be screened for TB?

Tumor Markers

Tumor markers are substances measured in blood, urine, or tissue that can provide information about cancer. Some are produced by cancer cells; others are produced by normal cells and can also increase in noncancerous conditions. Examples include PSA, CA 125, CEA, AFP, and HE4. What are tumor marker tests used for? Depending on the marker and clinical setting, these tests can help: Support a diagnosis alongside imaging, biopsy, and other findings. Guide treatment selection. Monitor response to treatment. Look for signs of recurrence or progression. Provide information about the likely course of a diagnosed cancer. Not every marker serves every purpose. A falling level may support a treatment response, while a rising level may prompt further evaluation. Neither change establishes what is happening on its own. Does an elevated tumor marker mean cancer? An elevated tumor marker does not automatically mean cancer, and a normal result does not rule it out. Benign conditions can affect results, and some cancers do not produce elevated markers.
