Can I order this test on its own?

Most labs can be ordered on their own with the “Lab Only” option, which includes a general results review. If you’d like your results personally reviewed — with a written Root Cause Report and personalized 12-week protocol — explore the 12-Week Program. Either way, add Tiffeny Parker as your practitioner when you register your kit so I can see your results.

Is this a medical diagnosis?

No. Functional lab testing is educational and is used to guide nutrition, lifestyle, and supplement strategy. It does not diagnose, treat, or cure any disease. Always work with your licensed healthcare provider for medical concerns.

How long do results take?

Most kits are collected at home in a single day and returned by prepaid mail. Results typically take about 2–4 weeks, depending on the panel.

Advanced Gut Microbiome Test

Also known as: DNA-based (PCR) stool microbiome profile

DNA-based stool testing for a deeper look at gut pathogens, microbiome balance, and digestion.

StoolAt-home collection kit

How to get this lab ↓

Standard stool testing grows organisms and examines them under a microscope. This profile uses DNA (PCR) technology to identify bacteria, viruses, and parasites with high sensitivity and to score overall microbiome balance. Full, essentials, and microbiome-only versions are available, chosen based on your history.

What it measures

Pathogens (DNA detection)

Bacterial, viral, and parasiticDetected by their DNA with high sensitivity.

Microbiome Balance

Dysbiosis scoreAn overall picture of gut balance.
Major beneficial bacterial groupsThe populations that support digestion and immunity.

Digestion & Inflammation (full version)

Pancreatic elastaseDigestive enzyme output.
CalprotectinGut inflammation.
Fat digestionHow well fats are absorbed.

Who this is for

For stubborn or complex gut symptoms that need a more sensitive look than a standard stool test.

Chronic or unexplained GI symptoms
Symptoms that persisted after a standard stool test

How we interpret it

We read every panel through a functional lens — optimal reference ranges, ratios, and cross-panel patterns. Results become part of your written Root Cause Report and your personalized 12-week protocol.

A deeper gut picture helps us target exactly what to clear and rebuild, so the minerals we replenish are actually absorbed.

Often paired with

Candida, Metabolic & Vitamins Test

Yeast, bacteria, mitochondrial energy, neurotransmitters, oxalates, and vitamin needs — from one urine sample.

Gut Bacteria & Parasite Test

Bacteria, yeast, parasites, H. pylori, digestion, and gut inflammation.

Leaky Gut Test

A stool marker of gut-lining permeability.

Common questions

Not sure which panels you need?

Start with the Root-Cause Fit Assessment. Takes about 3–5 minutes. If it looks like we're a good fit, you'll be invited to schedule a 45-minute consultation to discuss your health history, goals, and whether this program is the right next step for you.
