Your gut microbiota influences everything from digestion and immunity to metabolism and mood. The Gut Health Test reveals its functional output — what your gut bacteria are actually producing — and how that activity is affecting you.

Key Benefits

• Measures functional output – revealing how your gut bacteria and body work together to produce health-linked metabolites
• Science-backed markers – analyzes three key tryptophan-related metabolites linked to gut, immune, and metabolic health
• Advanced analysis – uses HPLC-UV-FLD technology for high-precision results
• Balance insights – shows how a protective metabolite from gut bacteria relates to other insightful markers
• Clear scoring – your results distilled into an easy-to-read Gut Health Index
• Personalized guidance – tailored diet and lifestyle recommendations, with a focus on fiber and polyphenols, based on your unique results
• Simple at-home self-test – dried blood spot (DBS) collection, no stool sample required

Taking your test

1. For optimal accuracy, perform this test on an empty stomach. Take your test in the morning after an overnight fast of at least 10 hours and complete it before consuming any food.

Only water is permitted during the fasting period. Zinzino Test is an approved in vitro diagnostics product for personal blood sample collection at home.

– First wash your hands with soap and rinse well with warm water and dry them.

2. Take out the sample card from the paper envelope.

Save the envelope for later use.

Tear off the SAVE part on the sample card and take a picture of the Test ID. You can ONLY see YOUR test result with your anonymous Test ID. Place the card with the two circles facing up on the table.

3. Stimulate blood flow by making big circles with your arm or shaking the hand downwards for 20 seconds.

4. Take out the single-use lancet. Remove the transparent safety cap and the lancet is ready to use.

Use alcohol wipe to clean the tip of your finger (middle finger is recommended).

Place the lancet against the lower part of the fingertip facing the collection paper on the table. Push the top of the lancet towards the finger until you hear a click. The lancet will automatically make a small prick in the finger

5. Do not touch the filter paper with your fingers.

6.  Fill one circle at a time with blood. Squeeze your finger gently and wait for a drop of blood to fall inside the circle by itself. If one drop of blood does not cover the circle, allow one more drop from your finger to drip immediately.

Leave the sample card in a horizontal position in room temperature for at least 10 minutes for the samples to dry well.

7. Insert the sample card back into the paper envelope. Then place the paper envelope into the metal bag and close it.

IMORTANT:
Do not remove desiccant packet inside the metal bag.

8. Place the closed metal bag into the big envelope with the laboratory address on it.

NOTE:
You MUST put the correct amount of postage stamps on the envelope before you put it in the mail box.
