May 29, 2025

Searching for a food sensitivity testing doctor near me in Newtown Square? You're not alone if you’ve wondered how certain foods might be affecting your digestion or energy levels. Food sensitivities can cause a range of symptoms, from bloating to fatigue, making daily life a challenge.

With advanced lab testing and physician-led guidance, you’ll get more than guesswork—personalized insights help uncover the root causes behind your symptoms so you can feel your best.

Understanding Food Sensitivity Testing

Food sensitivity testing evaluates your body's reaction to different foods by analyzing biological markers, such as antibodies or inflammatory mediators, found in your blood. These responses differ from food allergies, which involve a rapid immune reaction, and often present as ongoing symptoms like bloating, fatigue, or digestive discomfort after eating specific foods. In adult populations, up to 20% report adverse food reactions, making it essential to distinguish between intolerance, allergy, and sensitivity (NIH, 2021).

Validated lab panels test for immunoglobulin G (IgG) antibodies to hundreds of common foods. These results, when interpreted alongside symptoms and lifestyle history, identify patterns that can point to your personal food triggers. For example, people often see improvement in GI symptoms, energy levels, and skin health after targeted dietary adjustments based on their test outcomes. Clinical studies show that individualized elimination diets based on testing can reduce symptoms in up to 75% of adults with otherwise unexplained GI complaints (Aljada et al, 2022).

You benefit from advanced diagnostics, board-certified expertise, and tailored protocols designed by Dr. Onyx Adegbola, MD PhD DipIBLM—Physician-Scientist, Lifestyle Medicine Physician, Certified Nutrition Coach, and member of leading medical societies.

Blood Tests

Blood tests assess your body’s immune response to specific foods by measuring IgG antibodies. Dr. Onyx Adegbola’s oversight ensures that these tests—backed by evidence and clinical precision—screen for reactions to over a hundred common foods. After your blood sample is collected in-clinic, you receive a detailed analysis and interpretation. This method frequently identifies delayed food sensitivities missed by standard allergy panels. Your results guide customized nutrition plans and supplement recommendations that target root-cause imbalances and improve symptoms like bloating, fatigue, or skin changes.

Elimination Diets

Elimination diets systematically remove and then reintroduce foods from your daily meals to reveal which ones trigger symptoms. Under Dr. Onyx’s guidance, you track food intake and responses over several weeks. Data from your medical history and any lab results further personalize the process.

At-home testing kits let you collect a finger-prick blood sample in the comfort of your home and mail it to a certified lab. Dr. Onyx reviews the certified results with you in a virtual or in-person visit, integrating data on your symptoms, history, and lifestyle to formulate a practical action plan. These kits provide a convenient starting point for those unable to visit the clinic for immediate testing and help prioritize foods for further clinical evaluation.

Dr. Onyx Adegbola, MD PhD DipIBLM, brings extensive training from Columbia University, the University of Pennsylvania, and Johns Hopkins Medicine, ensuring thorough, science-based assessments every step.

Testing centers on blood sample analysis, which may require either a standard blood draw at the clinic or a finger-prick kit if you opt for at-home collection. The labs use validated immunoglobulin G (IgG) food panels, which evaluate your immune system’s response to hundreds of foods. This high-sensitivity approach helps identify patterns of food reactivity that can trigger persistent digestive, metabolic, or inflammatory symptoms.

You receive guidance from Dr. Onyx—a physician-scientist, certified nutrition coach, and member of the American College of Lifestyle Medicine, Institute for Functional Medicine, Obesity Medicine Association, and The Menopause Society—who reviews each testing step. Her oversight covers not just test administration but also the interpretation of complex immune markers, ensuring your results reflect your unique biology.

After lab analysis, you’ll meet directly with Dr. Onyx to review your results and discuss their clinical significance. She correlates your symptoms and test markers, identifying root-cause contributors such as gut permeability, immune imbalance, or metabolic stress. Using these insights, you receive custom dietary recommendations and anti-inflammatory nutrition strategies, designed to lower symptom burden and support long-term GI and immune health.

If your plan calls for a targeted elimination diet, Dr. Onyx guides you through systematic food exclusions and gradual reintroduction protocols, providing ongoing support to monitor progress and adjust recommendations based on your responses. You may also get advice on microbiome testing, personalized supplementation, or hormone/metabolic assessments if additional insights are necessary.

Ongoing monitoring is standard for all patients, allowing you to track improvements and refine your plan with expert input. With Dr. Onyx’s board certifications in obesity management, menopause care, and nutrition coaching, you access multidisciplinary guidance that supports not only digestive health but overall vitality and disease risk reduction.

Interpreting and Using Your Results

Food sensitivity test results provide a numeric and categorized breakdown of your body’s immune response to specific foods. Validated IgG food panels indicate reactivity levels to over 150 common foods, including dairy, wheat, nuts, seafood, and fruits. Moderate or high reactivity values suggest stronger immune responses, which, when paired with ongoing symptoms like bloating, fatigue, or skin changes, help identify likely triggers (NIH, 2023).

You gain context-rich insight into what each food category means for your gut health, metabolic function, and inflammation status. For example, a pattern of high reactivity to gluten-containing foods may indicate a need for temporary dietary elimination while underlying gut permeability is addressed. Low or absent reactivity suggests minimal contribution to your current symptoms.

Dr. Onyx Adegbola, MD PhD DipIBLM, reviews these test results with you during your consultation, combining findings with your health history, symptom log, and diagnostic data. As a physician-scientist and lifestyle medicine physician—certified in obesity management, menopause, nutrition coaching, and personal training—Dr. Onyx creates individualized care protocols anchored in evidence and clinical best practice.

Evidence-based dietary recommendations follow the review of your food reactivity profile. If your results demonstrate sensitivity to eggs, nuts, or soy, you receive a structured plan for ingredient substitutions, meal planning, and balanced, anti-inflammatory recipes that fit your nutritional needs—using clinical guidelines developed with organizations like the American College of Lifestyle Medicine and the Institute for Functional Medicine.

For symptom monitoring, you receive tools to track changes in digestion, energy levels, skin health, and sleep. Dr. Onyx schedules regular follow-up sessions, using symptom diaries and repeat lab testing to refine your plan based on your body’s responses and real-world experiences.

Supplement guidance is tailored from your results. If digestive or metabolic markers show suboptimal balance, you receive recommendations for targeted nutrients—such as digestive enzymes, probiotics, or micronutrients—with dosing and safety reviewed under physician supervision.

Lifestyle modifications complement dietary adjustments. When results reveal patterns linked to chronic inflammation or metabolic risk, Dr. Onyx leverages training from the Obesity Medicine Association and The Menopause Society to recommend physical activity regimens, mindfulness strategies, and sustainable routines supporting gut health and immune resilience.

You receive ongoing education and resources, anchored in up-to-date research and professional guidelines, empowering you to make informed choices and adapt your protocol as your health evolves. If co-existing medical conditions are present, your plan incorporates treatment recommendations and communication with your care team.
