1. What is TAU-KIT® and what is it used for
TAU-KIT®belongs to the group of medications called other diagnostic agents. TAU-KIT®is a breath test indicated to determine the presence in your stomach of a bacterium called Helicobacter pylori, which may be responsible for the discomfort you are experiencing.
This medication is for diagnostic use only.

Warnings and Precautions
Consult your doctor before starting to take TAU-KIT®
- A positive test result alone does not constitute an absolute indication for eradication treatment.
Diagnosis with other methods (endoscopy) may be indicated to examine the presence of any other complications, such as ulcers, autoimmune gastritis, or malignant tumors.
- If you have had a partial gastrectomy or are under 5 years old, you should inform your doctor, as there is not enough data to recommend its use in these cases.
- If you have a type of gastritis called atrophic gastritis, the breath test may have false-positive results, so it may be necessary to undergo other studies to confirm the infection.
- If you vomit during the test, it is necessary to repeat it, at least the next day on an empty stomach.
Other Medications and TAU-KIT®
If you are being treated with antibiotics for Helicobacter pyloriinfection, you should wait 4 weeks without medication before performing the diagnostic test with TAU-KIT®, as it could result in a false-negative result.

Important Information about Some Components of Citral pylori®.
