No prescription is needed.

Under what circumstances can I not take the test and what incompatibilities exist?

Certain circumstances do not allow the test to get reliable results about your gut microbiota. You cannot take the test if:

  • You’re pregnan
  • You are a minor
  •  In the last month, you have taken an oral antibiotic or antibiotic that affects the intestinal tract

If you have been taking antibiotics, we recommend that you wait at least one month from the last time they were taken.

In case of menstruation, although menstruation does not alter the results of the analysis, we advise not to collect the sample for the test during this period, to avoid possible contamination of the sample.

On the other hand, the test can be performed regardless of whether the user has undergone any surgery or is taking prebiotics and / or probiotics.

Apart from antibiotics, is there any other excluding medication?

There are no other exclusive medications to perform the test other than orally ingested antibiotics or that affect the intestinal tract.

3. Collect the stool sample and prepare it

How much sample must be collected?

The size of a pea is enough, but we recommend filling half of the tube with the help of the teaspoon that accompanies it to have more sample in case the analysis has to be repeated.

Does the sample have to be from the same day?

The sample that is introduced into the tube must be of the same deposition. If you do several in one day, it doesn’t matter which one you choose as sample. We recommend that you do not fill the tube with different stools over a different day or days.

If I already have a sample container, do I need to use the kit tube?

It is essential to use the collector tube found in the TestUrGut kit to ensure the viability of the sample within the analysis protocols of GoodGut SL.

Will the result of the analysis vary according to the consistency of the stool?

In the product definition the different Bristol scales (different levels of consistency) were taken into account and it was determined that consistency is indifferent.

How to understand the Bristol Stool Scale?

The Bristol Scale used is a visual and descriptive table that allows the stool to be classified according to its shape and consistency. It comprises 7 different categories and is used in common clinical practice for the diagnosis of intestinal problems. The main factor influencing the type of stool consistency is the time spent in the colon.
