When standard lab panels have not provided clear answers, the next step is often a more targeted investigation. Comprehensive Specialty Diagnostic Testing at The Longevity Center FL is a physician-directed evaluation designed to explore specific clinical questions that routine bloodwork is not built to answer. Led by Dr. Benjamin Kosubevsky, with advanced training in Osteopathic, Regenerative, and Integrative Medicine, specialty testing is available to patients in West Palm Beach and across South Florida who need a deeper look at environmental, infectious, metabolic, or inflammatory factors that may be contributing to persistent wellness concerns.
Not every patient requires specialty testing. These panels are selected based on your clinical presentation, health history, and the findings from your initial assessment. Dr. Kosubevsky determines which investigations are clinically appropriate for your situation—ensuring that testing is purposeful, not excessive.
Specialty diagnostic testing is a physician-guided evaluation intended to provide additional clinical insight when standard testing has not fully addressed a patient’s wellness concerns. It is not intended to independently diagnose, treat, cure, or prevent any specific disease. Some specialty panels referenced on this page are laboratory-developed tests (LDTs) and have not been cleared or approved by the U.S. Food and Drug Administration. Results should be interpreted within the context of a complete clinical evaluation. This service is not a substitute for evaluation by your primary care physician or specialist.
Rather than ordering a generic panel of tests, Dr. Kosubevsky selects specialty investigations based on clinical reasoning. Testing is organized across three investigation pathways, each addressing a distinct category of potential contributors to persistent symptoms.
Modern environments expose individuals to a wide range of substances that may accumulate in the body over time. When environmental exposure is suspected, testing may include evaluation of heavy metals (lead, mercury, arsenic, cadmium, and others), mycotoxin markers associated with mold exposure, and other environmental compounds. Peer-reviewed literature has documented the potential health effects of chronic, low-level heavy metal exposure across multiple organ systems, including neurological, cardiovascular, and immune function (Tchounwou et al., EXS, 2012; Jaishankar et al., Interdisciplinary Toxicology, 2014). For mold-related concerns, clinical evaluation may include mycotoxin screening alongside a review of environmental history and symptom patterns, consistent with published reviews on the health effects of mold exposure (Bush et al., Journal of Allergy and Clinical Immunology, 2006).
Certain chronic infections—particularly tick-borne illnesses—can be difficult to identify with standard screening. When clinical history and symptoms suggest a possible infectious contributor, Dr. Kosubevsky may recommend expanded testing for Lyme disease (Borrelia burgdorferi) and related co-infections, using methodologies that extend beyond the standard two-tier testing approach. The Infectious Diseases Society of America has published clinical practice guidelines acknowledging the complexity of Lyme disease assessment and the importance of clinical context in interpretation (Wormser et al., Clinical Infectious Diseases, 2006). Additional immune markers may also be evaluated to assess overall immune system activation, viral reactivation patterns, and inflammatory status.
For patients with symptoms that suggest an immune-mediated component—such as joint pain, skin changes, unexplained fatigue, or gastrointestinal disturbance—Dr. Kosubevsky may recommend expanded inflammatory and autoimmune marker panels. These may include advanced inflammatory cytokines, autoimmune antibody panels, and markers of intestinal permeability. This pathway is selected when clinical findings suggest that the immune system may be contributing to the patient’s symptom picture, and when standard autoimmune screening has been inconclusive.
For patients who have completed standard medical workups without receiving a satisfactory explanation for ongoing fatigue, pain, cognitive difficulty, or other persistent concerns.
For individuals with occupational exposure history, water damage in their home or workplace, dental amalgam history, or other environmental risk factors.
For patients whose symptoms span multiple body systems—neurological, musculoskeletal, gastrointestinal, and immune—suggesting a systemic contributor that standard testing may not capture.
For those with a history of tick bites, outdoor exposure in endemic regions, or symptoms consistent with tick-borne illness that have not been adequately investigated.
For patients about to begin chelation therapy, IV nutrient therapy, or other detoxification-focused services who need baseline specialty testing to guide treatment selection and monitor progress.

Comprehensive Specialty Diagnostic Testing at The Longevity Center FL is designed for patients who need a deeper investigation into the factors that may be driving their symptoms. If standard bloodwork has not provided the clarity you need, specialty testing may offer the additional insight required to move forward with confidence.
