Gut Health Test - Zinzino

Popis

The Zinzino Gut Health Test is your key to understanding how your gut bacteria influence your immune system, metabolism, and overall vitality. It’s not just a test — it’s a roadmap to better health, built on science, precision, and simplicity.

Comprehensive Gut Analysis
This advanced at-home test measures how your gut bacteria and body interact through tryptophan metabolism — a key process that connects gut health, immunity, and metabolic function. Using state-of-the-art HPLC-UV-FLD technology, the test provides high-precision results that translate complex biochemistry into clear, actionable insights.

What the Test Measures
Three key compounds are analyzed to assess your gut’s functional output:

Indole-3-Propionic Acid (IPA): A protective metabolite produced by gut bacteria from dietary tryptophan. Higher levels indicate stronger gut barrier integrity and antioxidant capacity.
Tryptophan (TRP): An essential amino acid that serves as a precursor for both IPA and kynurenine, influencing gut health and immune balance.
Kynurenine (KYN): A metabolite linked to immune activation and inflammation. Elevated levels can indicate metabolic stress and reduced microbial efficiency.

From these data points, the following key ratios are calculated:

IPA:TRP ratio: Reflects microbiome efficiency in converting tryptophan into beneficial metabolites.
KYN:TRP ratio: Indicates immune activation and inflammation level.
IPA:KYN ratio: Represents the balance between protective and stress-driven metabolic pathways.

All of these results are integrated into a single, easy-to-read Gut Health Index, giving you a complete picture of your gut-immune-metabolic status.

Why Tryptophan Metabolism Matters
Tryptophan metabolism is a crucial link between your gut, immune system, and metabolism. When balanced, your microbiome converts tryptophan into IPA and other beneficial compounds that strengthen your gut lining, regulate inflammation, and support mental well-being. When disrupted, more tryptophan is diverted into the kynurenine pathway — a stress-activated route associated with immune dysfunction and fatigue.

Understanding this balance allows you to make targeted improvements to your diet and lifestyle — with a focus on fiber, polyphenols, and gut-friendly nutrition — to restore and maintain healthy microbial function.

Certified Laboratory Testing
The test is analyzed by Vitas, an independent GMP-certified laboratory with more than 25 years of experience in high-precision chromatographic analysis. Each test kit complies with EU regulation 98/79/EB for in vitro diagnostic medical devices and carries the CE mark. Your sample is completely anonymous and linked only to your unique Test ID for secure result delivery.

How to Take the Test

Perform the test on an empty stomach, after fasting for at least 10 hours. Only water is permitted.
Wash your hands with warm water and soap, dry them thoroughly, and prepare the sampling card.
Take a photo of your Test ID and keep the SAVE section.
Stimulate blood flow by shaking your hand or rotating your arm for 20 seconds.
Use the sterile lancet to prick your fingertip and let a drop of blood fall into each circle on the card. Allow to dry for at least 10 minutes.
Place the card into the provided paper and metal bags, seal them with the desiccant inside, and return via mail using the supplied envelope.
