Comprehensive Blood Work

At Alessi Functional Health, we believe the body is one integrated system — not a collection of isolated parts. That’s why we go beyond the surface-level blood work offered by most insurance-based providers.

While conventional medicine often tests just enough to prescribe a medication, we look deeper, wider, and more holistically to uncover the root causes of your symptoms — before they turn into chronic disease.

Why Functional Lab Work Is Different

Most patients come to us with this story:
“My doctor said my labs were normal… but I still feel terrible.”

That’s because conventional ranges are designed to catch disease, not dysfunction. And often, doctors are only allowed to test what insurance will approve — which means dozens of underlying issues go undetected and untreated.

At Alessi Functional Health, we run comprehensive, system-wide panels that evaluate how all major systems are working together. This allows us to spot dysfunction early and personalize a care plan based on your biochemistry — not a generic prescription.

What We Test — and Why It Matters

Our most commonly used comprehensive lab panels include:

1. Comprehensive Blood Panel

This goes far beyond a basic CBC. We analyze:

• Full Hormone Profile – Estrogen, progesterone, testosterone, DHEA, cortisol
• Thyroid Function – Including TSH, free T3, free T4, reverse T3, and antibodies
• Metabolic Health – Blood sugar, insulin, HbA1c
• Inflammation Markers – CRP, homocysteine, ferritin
• Nutrient Levels – B12, iron, vitamin D, magnesium, and more
• Cardiac Risk Markers – Advanced lipid profile, triglycerides, LDL particle size

2. Leaky Gut Panel

This stool and intestinal barrier test screens for:

• Intestinal permeability (tight junction breakdown)
• Zonulin levels
• Inflammatory markers in the gut
• Immune system activation and hidden infections

3. Food Sensitivity Panel

Identifies delayed immune responses (IgG) to over 100 commonly eaten foods, helping us pinpoint what’s quietly driving your inflammation, bloating, fatigue, skin issues, or autoimmune flares.

4. Oxidative Stress Profile

Evaluates your body’s internal redox balance, including:

• Free radical activity
• Antioxidant capacity
• Cellular stress and aging markers

This test helps us determine how your body is managing inflammation, detoxification, and repair at the cellular level — often key for chronic illness, fatigue, or poor healing.

5. Gut Bacteria & Parasite Stool Test

One of the most important and overlooked tests — this advanced stool analysis checks for:

• Overgrowth of harmful bacteria or yeast (like Candida)
• Parasites and protozoa
• Short-chain fatty acid levels
• Inflammation markers
• Digestive enzyme function
• Beneficial flora diversity and balance

Your gut drives everything — from your immune system to your mood and metabolism. This test gives us a detailed snapshot of what’s really going on inside.

The Body Works Together — So We Test It That Way

Your gut affects your hormones. Your thyroid impacts your mood. Your blood sugar influences your brain. It’s all connected.

That’s why we don’t just run one or two markers — we look at the entire terrain to see where your body is struggling to self-regulate, and why. This gives us the information needed to build a personalized root-cause care plan that gets real results.

What Patients Are Saying

“I had been to five doctors who all said my labs were normal. Dr. Alessi ran a full blood panel, food sensitivity test, and gut screen — and within weeks I had answers that changed everything.”
— Christine D., Tampa FL

“I finally understand what’s going on in my body. Instead of getting another prescription, I got a real plan — and I’m healing for the first time in years.”
— Jonathan P., Wesley Chapel FL
