Advanced Lab Testing in Dallas – Fort Worth

You go to see your doctor for symptoms like fatigue, bloating, and aches. They run some tests. The results come back negative. Now what?

The problem could be that the doctor failed to order the right tests. Most people don’t know that not all lab tests are the same. You need Integrative Wellness Fx’s advanced testing to get to the root cause of your issues.

Our Dallas practice combines the best of modern testing and ancient medicine. We rely on what works and use every tool available. With this comprehensive view, our team can tailor personalized treatment plans that address each patient's specific needs and complexities, ultimately promoting better health and well-being.

Why Advanced Lab Testing

Lab testing plays a key role in promoting overall health and uncovering the underlying factors contributing to chronic diseases. By providing objective data on health markers, lab tests offer valuable insights into an individual's health status, allowing our functional medicine practitioners to detect potential issues at their earliest stages. This proactive approach enables timely interventions, potentially preventing the progression of diseases and improving treatment outcomes.

Furthermore, lab testing aids in identifying the root causes of chronic conditions by assessing biomarkers, hormone levels, genetic predispositions, and other crucial indicators. Our Dallas team wants to put together the pieces of your health puzzle, something you can’t do without advanced lab testing. Armed with this comprehensive understanding, healthcare providers can tailor personalized treatment plans that address the specific needs and complexities of each patient, ultimately promoting better health and well-being.

Our Tests

Our clinic uses this comprehensive test as a standard for most patients. The results help us determine the main sources of inflammation and deficiency in the body. This test measures all nutrients/minerals/vitamins, bacterial/fungal overgrowth, malabsorption, energy production and metabolism, toxicity, heavy metals, and MTHFR.

Advanced Nutritional, Metabolic, and Gut Analysis


Deficiencies in essential nutrients, minerals, and vitamins can significantly impact overall health and contribute to the development or exacerbation of chronic diseases. Testing for these factors helps identify deficiencies and allows healthcare providers to prescribe appropriate supplementation or dietary interventions to address them, thereby supporting optimal physiological function.

Bacterial/Fungal Overgrowth

Imbalances in gut microbiota, including bacterial and fungal overgrowth, have been associated with numerous chronic diseases such as irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and metabolic syndrome. Testing for overgrowth allows for targeted interventions such as antimicrobial therapies, probiotics, and dietary changes to restore microbial balance and alleviate symptoms.


In some cases, your gut can’t absorb the nutrients you need – no matter how many you take. This leads to deficiencies and systemic complications. Testing for malabsorption helps identify underlying gastrointestinal disorders such as celiac disease, Crohn's disease, and pancreatic insufficiency, guiding appropriate management strategies to optimize nutrient absorption and improve clinical outcomes.

Energy Production and Metabolism

Dysfunctions in energy production and metabolism can contribute to chronic fatigue, metabolic disorders, and other systemic health issues. Advanced testing in Dallas can look for markers of energy metabolism, such as mitochondrial function and metabolic hormones, provide insights into underlying metabolic imbalances, and guide targeted interventions to support energy production and metabolic health.

Energy Production and Metabolism

Exposure to environmental toxins, pollutants, and heavy metals can have detrimental effects on various organ systems and contribute to the pathogenesis of chronic diseases such as neurological disorders, cardiovascular diseases, and cancer. Testing for toxicity levels helps assess individual exposure risks and guides detoxification protocols to minimize toxin burden and mitigate associated health risks.

Heavy Metals

Heavy metal toxicity can impair physiological function and contribute to chronic illnesses affecting the nervous, cardiovascular, and immune systems. Testing for heavy metals like lead, mercury, arsenic, and cadmium helps identify exposure levels and guides targeted interventions such as chelation therapy, dietary modifications, and lifestyle changes to reduce metal burden and improve health outcomes.

MTHFR (Methylenetetrahydrofolate Reductase) Mutation

MTHFR gene variants can affect methylation processes, folate metabolism, and detoxification pathways, predisposing individuals to various chronic diseases including cardiovascular disease, depression, and neurological disorders. Testing for MTHFR mutations helps identify genetic susceptibilities and informs personalized treatment approaches such as supplementation with methylated forms of vitamins and lifestyle modifications to optimize methylation pathways and reduce disease risk.

Comprehensive Bloodwork

Utilizing silicon micro-array chip technology allows us to test a comprehensive array of advanced markers for the same price as your average blood test. The blood is how your body moves many key elements around the body, and elevated or lowered levels of vitamins, hormones, and other organic compounds can give us a good look into specific health issues.

Hormone Panel

Hormones play a crucial role in regulating numerous physiological processes, including metabolism, reproduction, and mood. A hormone panel assesses levels of hormones such as estrogen, progesterone, testosterone, cortisol, and thyroid hormones, providing insights into hormonal balance, reproductive health, adrenal function, and thyroid function.

Thyroid Testing with Antibodies

Thyroid function tests, including TSH (thyroid-stimulating hormone), T3 (triiodothyronine), and T4 (thyroxine), along with thyroid antibody tests (such as anti-TPO and anti-Tg antibodies), help diagnose thyroid disorders such as hypothyroidism, hyperthyroidism, and autoimmune thyroid diseases like Hashimoto's thyroiditis and Graves' disease.


Cardiometabolic blood tests assess markers associated with cardiovascular health and metabolic syndrome, including lipid profile (total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides), fasting glucose, insulin, and markers of inflammation (e.g., high-sensitivity C-reactive protein). These tests help identify risk factors for heart disease, diabetes, and metabolic syndrome, guiding preventive strategies such as lifestyle modifications and medication management.

Energy Production and Metabolism

We’ve all heard about cholesterol, but not everyone knows what “healthy levels” mean. Cholesterol testing measures levels of various lipids in the blood, including total cholesterol, LDL cholesterol ("bad" cholesterol), HDL cholesterol ("good" cholesterol), and triglycerides. Abnormal lipid levels are associated with an increased risk of atherosclerosis, heart disease, and stroke. Cholesterol screening helps assess cardiovascular risk and informs interventions such as diet, exercise, and medication.

Sugar Metabolism

Blood tests such as fasting glucose, hemoglobin A1c, and insulin levels assess sugar metabolism and glycemic control. These test, offered at our clinic in Dallas, are essential for diagnosing diabetes, monitoring blood sugar levels, and evaluating insulin resistance, guiding treatment strategies to optimize blood sugar control and prevent complications associated with diabetes.


Inflammatory markers such as high-sensitivity C-reactive protein (hs-CRP), erythrocyte sedimentation rate (ESR), and interleukin-6 (IL-6) provide insights into systemic inflammation, which is linked to various chronic diseases, including cardiovascular disease, diabetes, and autoimmune disorders. Monitoring inflammation helps assess disease activity, guide treatment decisions, and track response to therapy.


Blood tests such as complete blood count (CBC) and iron studies assess red blood cell count, hemoglobin levels, hematocrit, and iron status, helping diagnose and monitor anemia. Anemia can result from nutritional deficiencies, chronic diseases, or bone marrow disorders and can lead to fatigue, weakness, and other complications if left untreated.


Blood tests such as white blood cell count (WBC), immunoglobulin levels, and specific antibody tests evaluate immune function and response to infections or vaccinations. Monitoring immune parameters helps assess immune competence, diagnose immune deficiencies or autoimmune diseases, and guide treatment strategies.

Vitamin D

Vitamin D testing measures serum levels of 25-hydroxyvitamin D, a marker of vitamin D status. Adequate vitamin D levels are essential for bone health, immune function, and overall well-being. Deficiency is associated with an increased risk of bone disorders, autoimmune diseases, and other health issues. Monitoring vitamin D levels helps assess status and guide supplementation to maintain optimal levels for health.

Other Tests We Offer at Our Dallas Practice

At Integrative Wellness Fx in Dallas, we provide comprehensive testing solutions to empower individuals on their journey to optimal health and wellness. Through advanced diagnostics such as genetic analysis, food sensitivity testing, intestinal permeability assessment, GI stool analysis, and environmental testing, we uncover underlying factors contributing to your health challenges. Our comprehensive approach extends to Lyme and coinfection testing, brain autoimmunity assessments, organic acids analysis, and advanced hormone and neurotransmitter profiling.

By offering a wide range of tests, we can identify root causes of health issues and tailor personalized treatment plans that address individual needs. With a focus on integrative and functional medicine principles, we aim to support holistic healing and empower individuals to achieve vibrant health and well-being.

Food Sensitivity

The Food Sensitivity Complete panel assesses sensitivity to 209 common foods in the Western diet and food additives such as preservatives, artificial sweeteners, emulsifiers, food dyes, and pesticides, which can cause chronic inflammation and increased intestinal permeability (leaky gut). 

Traditional tests like ANA or ENA panels don’t provide detailed results, nor do they catch a majority of autoimmune issues. This is because these tests primarily focus on the autoimmunity of the connective tissues. We’ve found that auto-antibodies can exists for any tissue of the body, including the brain and nervous system. Our practitioners will choose which kind of autoimmune panel is best for your case, depending on your symptoms and presentation. And yes...autoimmunity can certainly be treated and reversed!

Autoimmunity Panels

Comprehensive Stool Analysis by Genova Diagnostics

This test is a comprehensive assessment of complete gut health, assessing the root cause of most GI issues. The combination of PCR, culture, and microscopic testing methods ensures any and all relevant organisms are identified.

Urine Hormones by Dutch Testing

Discover whether your hormones are imbalance with our extremely convenient urine test. This test will provide analysis of 35 different hormones: estrogen, progesterone, testosterone, DHEA-S, and cortisol along with their metabolites.

Neurotransmitters Panel

The Neurotransmitters panel evaluates the levels of key neurotransmitters and their metabolites within the brain and nervous system. Neurotransmitters are chemical messengers that enable signal transmission from one neuron (brain cell) to another target cell. This test is particularly useful if you have been diagnosed with neurological disorders such as Alzheimer's disease, Parkinson's disease, ADD/ADHD, Autism Spectrum Disorder, or mood disorders.

Chronic Infections

Have you been struggling with a chronic infection that doesn’t resolve on its own? This test checks for common tickborne diseases (which have more than doubled in 13 years and represent 77% of all vector-borne disease reports). Let’s see what is causing your troublesome symtpoms.

Celiac & Intestinal Permeability Panel

The Wheat Zoomer panel evaluates wheat sensitivity, autoimmune diseases, and the stability of the intestinal barrier. This test is beneficial if you suspect wheat sensitivity, multiple food sensitivities, intestinal permeability, autoimmune disorders, or chronic inflammation.

Total Tox Burden 

Toxic exposure is a daily reality, but toxic overload can strain our bodily systems and manifest in various ways. Toxins can cause elevated oxidative stress and place increased demands on the body's detoxification pathways, especially the liver. When the liver cannot effectively eliminate toxins or infectious byproducts, these substances can obstruct normal detox pathways, leading to a range of chronic inflammation symptoms.

Functional medicine puts the patient first. We know that every person is unique, which means addressing the root of disease means personalizing your wellness plan. When you work with Integrative Wellness Fx, we optimize foundational systems of the body such as digestion, detoxification, immune function, energy regulation, and hormonal balance.

Functional medicine practitioners spend time with their patients, listening to their histories and examining the interactions between genetic, environmental, and lifestyle factors that can influence long-term health and complex, chronic diseases. Thus, functional medicine supports each individual's unique expression of health and vitality.

Chronic disease is where functional medicine truly shines. Many people need targeted, intensive interventions to get their bodies working right. We don’t like to focus on slow, drawn-out treatment plans that make small changes here and there. Instead, we want to make the key changes that will accelerate your wellness and recovery. Success isn’t determined by the prescription of a single drug or miracle cure but instead by the synergy invoked by an array of medicinal herbs, nutrients, and changes in diet, lifestyle, and awareness.
