Purpose and use
The ITEST HELICOBACTER kit is designed for rapid identification of Helicobacter pylori in gastric mucosal biopsy samples by biochemical method. The kit is able to distinguish ulcer disease etiologically related to Helicobacter pylori infection from Helicobacter pylori negative cases due to other specific causes (e.g. gastrinoma, Crohn’s disease, etc.). The detection of peptic ulcers caused by Helicobacter infection allows early initiation of effective anti-Helicobacter treatment.
Principle
Helicobacter pylori produces urease, the detection of which is based on the change in pH when ammonia is produced.
Procedure
- Add 2 drops of diluent to the detection tube with dehydrated substrate. After complete dissolution, add the biopsy material to the solution. Close the tube and incubate for 3–4 hours at room temperature. If necessary, incubate the tubes until the next day.
Evaluation
Positive reaction (presence of Helicobacter pylori in the sample) results in the substrate turning pinkish-purple to purple during incubation. If the reaction is negative, the colour of the substrate does not change during incubation, i.e. it remains yellow to yellowish-orange.
Important
- The ITEST HELICOBACTER kit is supplied in packs with 25 tests (Cat. No. SO 331) and is for in vitro use only.
- Keep the kit in a dark place at 2–8 °C and use by the expiry date on the label.
- If the primary packaging of the IVD is damaged, do not use and contact the manufacturer.
- Dispose of unused IVDs and empty packaging in accordance with the Waste Act No. 185/2001 Coll.
