Immune & Inflammatory Conditions
When the immune system loses self-tolerance, suppressing symptoms is only half the battle.
At Clark Wellness, we investigate the root triggers of autoimmune disease and chronic inflammation—including gut permeability (leaky gut), molecular mimicry from stealth infections, food reactivity, and environmental toxin overload.
The Autoimmune Triad
According to Functional Medicine research, autoimmune disease requires three factors: genetic susceptibility, an environmental trigger (virus, toxin, stress), and intestinal permeability (leaky gut). By healing the gut barrier and removing triggers, we restore immune balance.
View Functional Medicine Program DetailsImmune Disorders & Inflammatory Syndromes
Autoimmune Diseases
Lupus, Rheumatoid Arthritis, Psoriasis, Celiac, Sjogren's, and Hashimoto's thyroiditis.
Long COVID / Long-Haul COVID
Persistent fatigue, brain fog, shortness of breath, palpitations, and joint pain lasting months after acute infection — driven by viral persistence, immune dysregulation, and microvascular inflammation.
Chronic Fatigue Syndrome (ME/CFS)
Profound exhaustion accompanied by post-exertional malaise and mitochondrial dysfunction.
Fibromyalgia & Chronic Pain
Widespread musculoskeletal pain, tender points, and heightened nervous system pain sensitivity.
Histamine Intolerance & MCAS
Mast Cell Activation Syndrome causing unexplained flushing, hives, racing heart, or food reactions.
Recurrent Infections
Frequent sinus infections, EBV reactivations, or persistent susceptibility to seasonal bugs.
High Inflammatory Biomarkers
Elevated hs-CRP, ESR, or ANA levels that standard labs fail to explain.
Re-educating the Immune System
Our goal is not merely immune suppression, but immune modulation—helping your body regain tolerance and dampening auto-antibody flares.
Advanced Antibody & Gut Testing
Utilizing Cyrex array testing, Gut Zoomer intestinal permeability panels, and comprehensive food reactivity profiles.
Anti-Inflammatory Nutrition
Personalized Autoimmune Protocol (AIP), Low-Histamine, or Elimination diets with 1:1 health coaching guidance.
Targeted Immunomodulation
Nutaceuticals like Curcumin, Resveratrol, Omega-3s, SPM resolvins, and Low-Dose Naltrexone (LDN) when appropriate.

Autoimmune Zoomer® by Vibrant Wellness
A comprehensive blood test that detects autoantibodies against 26+ tissue antigens — revealing hidden autoimmune activity years before symptoms escalate and standard labs turn positive.
Multi-Tissue Autoantibody Screen
Detects autoantibodies to 26+ organs and tissues — including thyroid, brain, joints, gut, heart, skin, kidneys, and pancreas — for a full-body autoimmune map.
Early Detection, Before Damage
Identifies elevated autoantibodies in the subclinical stage — often years before conventional ANA or disease-specific panels register a problem.
Brain & Neural Tissue Markers
Screens for autoantibodies to neural antigens linked to brain fog, anxiety, depression, and neuroinflammation driving Long COVID symptoms.
Gut Barrier & Food Reactivity
Evaluates antibodies tied to intestinal permeability (leaky gut), celiac, and cross-reactive foods that fuel immune activation.
Thyroid & Endocrine Autoimmunity
Measures autoantibodies to thyroid tissue and endocrine organs — catching Hashimoto's, Graves', and adrenal autoimmunity early.
Joint, Cardiac & Skin Targets
Assesses autoantibodies to collagen, cardiac tissue, and skin antigens — relevant for rheumatoid, lupus, psoriasis, and cardiovascular inflammation.
Viral & Infection Triggers
Helps connect autoimmune flares to viral triggers such as EBV, SARS-CoV-2 (Long COVID), and other stealth infections that ignite immune dysregulation.
Mitochondrial Autoantibodies
Detects antibodies against mitochondria — a key driver of the profound fatigue and post-exertional malaise seen in Long COVID and ME/CFS.
Personalized Immune Roadmap
Results guide a targeted protocol — removing triggers, healing the gut barrier, and modulating the immune system instead of blanket suppression.
Why We Trust Autoimmune Zoomer® for Immune & Long COVID Care
Autoimmune conditions — including Long COVID — rarely start in the tissue being attacked. They begin with a trigger, a leaky gut barrier, and an immune system that has lost self-tolerance. Autoimmune Zoomer® gives Angelica Clark, PA-C, IFMCP a precise, full-body antibody map so she can calm the immune response at its source instead of chasing symptoms one organ at a time.

Functional medicine at its best! Angelica is extremely knowledgeable and digs for the root of the issues, not just temporary fixes. The extensive testing gave us clear answers we couldn't get anywhere else.

I could not have asked for something better. They are my saving grace. Six months ago, I did not care if I lived or died. I had been to several other doctors with no answers. Angelica gave me my life back.
