Precision Diagnostics for Personalized Functional Medicine

by Dr. Rashel Tahzib | Advance Health Integrative Medicine

Comprehensive, Root-Cause Testing for Modern Health

At Advance Health Integrative Medicine, Dr. Rashel Tahzib offers one of the most comprehensive collections of advanced biomarker tests available in integrative and functional medicine today.

These next-generation diagnostic tools uncover the root causes of fatigue, autoimmune disease, infertility, chronic inflammation, hormonal imbalance, and gastrointestinal disorders that often remain undetected with standard laboratory testing.

Our testing approach provides an in-depth analysis of biochemistry, genetics, metabolism, detoxification, immune regulation, and hormonal function—allowing for precise, individualized treatment that restores balance and resilience from the cellular level up.

Why Choose Advanced Biomarker Testing

Conventional testing often measures only a fraction of what contributes to health or disease.
Dr. Tahzib’s functional diagnostic panels look beyond symptom management to identify the early biochemical shifts that precede illness—so that interventions can be both preventive and curative.

By combining advanced testing with clinical expertise, we can:

• Detect disease risk before it manifests

• Identify hidden drivers of chronic symptoms

• Customize nutritional, hormonal, and detoxification therapies

• Track your body’s healing progress over time

Validated, Research-Based Laboratory Partners

We collaborate only with high-complexity CLIA-certified laboratories known for reproducibility and scientific integrity. Every test we offer is evidence-based and clinically relevant, ensuring accuracy and actionable results.

Our Specialized Testing Panels

Genetic and Epigenetic Testing

Genetic analysis provides insight into how your DNA influences detoxification capacity, inflammation, nutrient metabolism, and hormonal balance.
Epigenetic markers can reveal how lifestyle, nutrition, and environmental factors regulate gene expression.
These results help identify predispositions to cardiovascular disease, autoimmunity, neurodegeneration, and cancer, guiding precision prevention strategies.

Advanced Cardio-Metabolic Panels

Our cardiometabolic testing evaluates far more than traditional cholesterol levels.
By assessing lipoprotein particle size, inflammatory markers (hs-CRP, Lp-PLA2), insulin sensitivity, and metabolic indicators, we gain a clear understanding of cardiovascular and metabolic health risks—essential for preventing heart disease, diabetes, and metabolic syndrome.

Comprehensive Nutritional and Metabolic Profiles

This panel measures a wide range of biochemical markers, including vitamins, minerals, amino acids, organic acids, and fatty acids.
It provides a detailed snapshot of mitochondrial function, detoxification pathways, and nutrient reserves, helping to identify underlying contributors to fatigue, mood changes, and chronic illness.

Functional Stool and Microbiome Analysis

A three-day comprehensive stool study assesses microbiome balance, digestive enzymes, inflammation, and pathogenic microorganisms.
This analysis reveals the root causes of IBS, autoimmune disorders, leaky gut, and malabsorption syndromes—critical components of gut-healing protocols.

Food Sensitivity and Allergy Testing

We identify both immediate and delayed immune responses to foods that can drive systemic inflammation, digestive distress, and skin or autoimmune reactions.
Results guide elimination and reintroduction protocols, combined with gut barrier repair and microbiome restoration strategies.

Zonulin, Histamine, and DAO Testing

These biomarkers assess intestinal permeability, mast cell activity, and histamine metabolism, revealing hidden contributors to eczema, migraines, anxiety, IBS, and autoimmune reactivity.

Intestinal Permeability Testing

This noninvasive test measures absorption and mucosal integrity, offering insight into leaky gut syndrome, chronic inflammation, and nutrient malabsorption.

SIBO Breath Testing

Small Intestinal Bacterial Overgrowth (SIBO) is detected by measuring hydrogen and methane gas production after carbohydrate ingestion.
This test helps diagnose causes of bloating, abdominal discomfort, and poor nutrient absorption.

Heavy Metal and Environmental Toxin Panels

We measure body burden from mercury, lead, arsenic, cadmium, and endocrine-disrupting chemicals such as phthalates and parabens.
Data guides personalized detoxification protocols that support safe elimination and metabolic repair.

Neurotransmitter and Brain Chemistry Profiles

This advanced testing evaluates serotonin, dopamine, norepinephrine, GABA, and related metabolites, revealing biochemical patterns associated with anxiety, depression, cognitive decline, and insomnia.

Comprehensive Thyroid Testing

Beyond standard TSH, we measure Free T3, Free T4, Reverse T3, and thyroid antibodies to detect autoimmune thyroiditis (Hashimoto’s, Graves’) and subclinical thyroid dysfunction missed by conventional panels.

Male and Female Hormone Panels

These panels assess estrogen, progesterone, testosterone, DHEA, and cortisol, identifying imbalances affecting fertility, menopause, andropause, mood, and metabolism.
Results guide tailored bioidentical hormone and lifestyle protocols.

24-Hour Urinary Hormone and Metabolite Testing

This comprehensive test evaluates hormone production and detoxification, providing key insight into estrogen metabolism, PMS, menopause, and cancer risk modulation.

Lyme and Chronic Infection Panels

We screen for Lyme disease and co-infections (Babesia, Bartonella, Ehrlichia) that often underlie fatigue, chronic pain, and autoimmune syndromes.

Adrenal Stress Index (ASI)

Assesses diurnal cortisol and DHEA rhythms to evaluate adrenal fatigue, stress adaptation, and circadian dysfunction.
Results guide restoration of energy, sleep, and resilience through nutritional and lifestyle strategies.

Kryptopyrroluria (KPU/HPU) Testing

Identifies a biochemical imbalance leading to zinc, vitamin B6, and biotin depletion, often seen in chronic illness, anxiety, or detoxification challenges.

Functional Blood Chemistry and Metabolic Panels

Standard blood work is interpreted through a functional medicine lens, focusing on optimal—not just “normal”—ranges.
This allows early detection of patterns related to inflammation, insulin resistance, and nutrient depletion.

The Advance Health Difference

At Advance Health Integrative Medicine, every test is interpreted personally by Dr. Rashel Tahzib, a physician with decades of experience in Functional and Integrative Medicine and among the earliest doctors certified by the Institute for Functional Medicine (IFM).

Our practice emphasizes:

• Root-cause investigation rather than symptom suppression

• Precision diagnostics backed by scientific validation

• Personalized treatment protocols integrating nutrition, detoxification, hormone optimization, and lifestyle medicine

This level of individualized care allows patients to experience measurable improvement in energy, focus, digestion, mood, and long-term health.
