The Sampling Kit

Why do you require a stool sample?

Turns out your stool can tell a lot about the state of your health. Your stool can be a reflection of your diet, fluid intake, medication use, or lifestyle. Your stool type is also related to your microbiome.

How do I collect a stool sample?

Open the tube by twisting and pulling, ensuring that the swab doesn’t come into contact with any other surfaces as this can interfere with the sample. Then, after a bowel movement, lightly touch the round end of the swab to the soiled toilet paper to collect a small smear. 

It’s important not to overload or underload your sample. You’ll receive images to reflect the correct amount with your gut microbiome sampling kit.

Once you’ve collected your sample, place the swab in the tube and click to close.

Where do I send my sample?

Once you’ve taken your sample, place the closed tube in the reply paid envelope included in your sampling kit and seal. Then return to our testing lab by posting in any Express Australia Post box.

When is the ideal time to collect a sample?

It’s best to collect your sample at a time when you have maintained regular daily and dietary habits for at least two weeks. It is also important to try and collect a sample from a bowel movement that is considered typical for you (i.e. some people experience a bowel movement first thing in the morning every day – this is considered a typical bowel movement).

I touched my test swab, what do I do?

If you think you’ve touched your test swab while collecting your sample, please do not return the sample back to our lab until you have contacted us at [email protected] to confirm whether the sample is suitable or a replacement sampling kit is required. 

We provide a replacement sampling kit to the limit of one.

Do I need to fast before collecting my sample?

No. There is no need to fast before collecting your sample. The aim of our gut microbiome test is to learn what your “normal” gut microbiome looks like. It’s best to collect your sample when you’re maintaining regular daily habits and diet for at least two weeks before sampling.

Can I collect my sample if I’ve been taking antibiotics?

Based on the existing literature, we suggest waiting at least one month after short-term antibiotic use before testing.

Current research shows that the effects of taking broad-spectrum antibiotics for between 5-10 days can exist in a person’s gut microbiome for a year or longer. The gut microbiome does begin to recover soon after antibiotics are stopped, with studies observing the majority of gut microbiota returning to pre-treatment levels after 1-2 months.

Can I collect my sample during menstruation?

To avoid contamination of your sample, we suggest that you avoid collecting your sample during the menstruation period.

Can I collect my sample if I have an illness or disease?

Yes. Vidality is a non-invasive method of testing your gut microbiome that can be completed in the privacy of your home whenever suits you.

Will taking medication interfere with my test results?

Certain medications, such as antibiotics, immunotherapy, immunosuppressants, chemotherapy, cholesterol lowering drugs, acid reflux and indigestion treatment, and the diabetes medication ‘metformin’ can alter your gut microbiome, however this doesn’t mean you should avoid gut microbiome testing. Consult with your doctor before making any changes to your medication.

Can I order the test without ordering the supplement?

Vidality Plans include both the gut microbiome test and Precision Prebiotics. These cannot be purchased separately.

The Gut Microbiome Test

How long will it take to get my sample analysed?

It takes our expert researchers between 2-4 weeks to process and analyse a sample once it has been received in our lab. We’ll keep you updated on the progress of your results via the online portal.

How can I use the information generated from Vidality gut microbiome testing?

Our testing enables you to gain a better understanding about 6 features of your unique gut microbiome, called Vidal Signs. This information is used to create your custom prebiotic blend. The 6 Vidal Signs relate to your microbiome’s capacity to produce:

  • Propionate
  • Butyrate  
  • Hexa-acylated lipopolysaccharide
  • Hydrogen Sulphide
  • Trimethylamine
  • β-glucuronidase

Vidality gut microbiome testing is not a diagnostic tool and cannot be used to diagnose or treat medical conditions.

Will Vidality gut microbiome test diagnose gut health issues?

The results from our gut microbiome testing are intended for informational purposes only. They are not intended to be used to diagnose medical conditions. That being said, the test will provide you with an overview of the microorganisms present in your microbiome, which may in turn provide insight into your overall gut health.

The Report

Where can I find my report once it’s available?

After our scientists have analysed your sample, your report will be available for viewing in the Vidality online portal, and you’ll receive notification that it’s ready.

If you experience any issues in accessing your report, please contact us via the Vidality online portal.

What information is included in the 6-Dimension report?

Your personalised report is generated to show you the members of your microbial community, what your microbial community is capable of, and how your microbial community compares to others.

I don’t understand my report, can I speak to someone about it?

The results of your gut microbiome test are interpreted into easy-to-understand information by our team of experts. However, if you require assistance in gaining a deeper understanding of your report, you can contact us via the Vidality online portal.

The Supplement

What ingredients are used in the supplements?

Our pharmacists formulate your Precision Prebiotics using dietary ingredients supported by high levels of scientific evidence, such as fructooligosaccharides (FOS), diindolylmethane (DIM), pomegranate Extract, glucomannan, b-glucans, ellagic acid, and arabinoxylan.

You can learn more about our Precision Prebiotic ingredients on our ‘Learn The Science’ page.

How do the pharmacists decide how much of each ingredient I need in my supplement?

Our pharmacists increase or decrease the level of each ingredient based on the measurements of specific markers in your sample. For each of the markers our pharmacists analyse, they proportionally scale the amount of the relevant ingredient in your blend.

How do I prepare the supplement blend for consumption?
To prepare your blend:

  1. Use the measuring scoop provided
  2. Add the powder to a liquid of your choice (water, juice, smoothie)
  3. Mix well in a shaker or blender
  4. Enjoy!
What is the correct dosage?

For the first 7 days, start with a lower dose than indicated on the label, so that your gut microbes have time to adjust. 

Day 1-7: 1 scoop

Day 8-14: 2 scoops

Day 15-21: 3 scoops

Day 22-28: 4 scoops

Are there any side effects of taking the supplement?

The most common side effects of taking supplements that interact with the gut microbiome are gastrointestinal complaints like bloating, flatulence, diarrhoea or constipation. These side effects are normally only experienced short-term as the gut adjusts to the changes that are taking place. This is why we recommend slowly increasing your dose over the course of a week.


Is the supplement gluten-free?

Not all of our dietary interventions are gluten-free. As part of the Vidality Day of Sampling questionnaire, we ask about your dietary requirements. If you’re unable to consume gluten for any reason, our pharmacists will not include ingredients containing gluten in your Precision Prebiotics.


Is the supplement dairy-free?

Yes, the ingredients used in our Precision Prebiotics are dairy free.

Can I order a supplement without ordering the gut microbiome test?

No. Vidality Plans include both the gut microbiome test and Precision Prebiotics. Without the results generated through our gut microbiome testing, our pharmacists won’t have the information they need to formulate a personalised blend of Precision Prebiotics for you.
