Functional Lab Testing and Blood Work

Understanding Functional Medicine Testing

Functional medicine testing examines how your body’s systems are working at a deeper level to help identify the underlying factors contributing to your symptoms. Rather than looking only for disease, these tests identify imbalances, deficiencies, and patterns that may be contributing to digestive issues, hormonal changes, fatigue, inflammation, and more.

At Vitalita Wellness Institute, we use evidence-informed functional testing to personalize your care plan and help you understand your body more clearly. These tests provide objective data on how your hormones, gut health, metabolism, and nutrient pathways are functioning so we can build targeted, effective treatment strategies.

Functional testing is never mandatory, but it can provide valuable insight—especially when symptoms have been persistent, confusing, or unresponsive to standard approaches.

Why We Use Functional Testing

Functional testing helps us:
  • Identify root causes more quickly
  • Gain objective data specific to your body
  • Personalize nutrition and supplementation
  • Track progress over time
  • Address complex or long-standing symptoms
  • Support you with clear, actionable data

We only recommend testing when it will meaningfully improve your care plan.

What Functional Medicine Testing Can Reveal

These tests help assess:
  • Hormone balance
  • Metabolism and blood sugar patterns
  • Stress and adrenal function
  • Gut inflammation
  • Digestive enzyme activity
  • Microbiome health
  • SIBO and bacterial overgrowth
  • Candida overgrowth
  • Nutrient deficiencies
  • Mitochondrial and energy production markers
  • Neurotransmitters imbalances
  • Food sensitivities
  • Detoxification pathways
  • Toxic exposure

Understanding these patterns helps us identify the root contributors to your symptoms and build a more precise, effective treatment plan.

OAT Test (Organic Acids Test)

The OAT test evaluates metabolic byproducts in urine to assess:

  • Mitochondrial function
  • Energy production
  • Neurotransmitter metabolites
  • Oxidative stress
  • Detox pathways
  • Certain nutrient deficiencies
  • Microbial overgrowth
  • Toxic exposure

This test is particularly useful for:

  • Autoimmune disorders
  • Cardiovascular concerns
  • Chronic fatigue
  • Diabetes/ insulin resistance
  • Digestive issues
  • Fibromyalgia
  • Mood symptoms (Anxiety and Depression)
  • Neurological concerns

  • Liver and kidney function
  • Lipids and cardiometabolic risk
  • Hormone levels (when appropriate)

We review your blood work using both standard medical reference ranges and functional “optimal ranges” to identify subtle imbalances that may be contributing to your symptoms.
