Urease test for h. pylori: procedure, results and application

Urease and h. pylori – what is the relationship between them?

Helicobacter pylori, also known as H. pylori, is a bacterium that can cause gastrointestinal infections in humans.One of the key mechanisms for the survival of H. pylori in the gastric environment is its ability to produce an enzyme called urease.Urease is an enzyme that converts urea into ammonia and carbon dioxide.In H. pylori infection, the presence of urease is a key indicator, which is why the urease test is used to diagnose this infection.

What is a urease test?

The urease test is a diagnostic laboratory test that aims to detect the presence of H. pylori in the patient’s digestive system.The basis of this test is the ability of H. pylori to secrete urease, which is then detected and assessed.The urease test is relatively simple, non-invasive and quick to perform, which makes it a popular diagnostic tool.

When should a urease test for h.pylori be performed?

A urease test for H. pylori is usually recommended in the following situations:

• Symptoms of H. pylori infection, such as abdominal pain, nausea, vomiting, heartburn, or indigestion.
• The mission is to suspect a stomach or duodenal ulcer, which may be caused by this bacterium.
• Monitoring the effects of treatment for H. pylori infection to assess whether the treatment was effective.
• Screening for H. pylori in patients at risk for this infection, for example if there is a family history of the infection.

What does a urease test for h. pylori look like?

The urease test procedure for H. pylori is relatively simple and can be performed in a doctor’s office or laboratory.Here are the steps that are typically performed during this test:

1. The patient must provide a sample of his or her stomach fluid.This process can be performed using a probe placed in the patient’s stomach or by taking a saliva sample that contains gastric contents.
2. The sample is placed in a special container that contains a substance containing urea.
3. If H. pylori is present in the sample, the bacterium will secrete the enzyme urease, which converts urea into ammonia and carbon dioxide.
4. The presence of ammonia is then detected using special chemical indicators or laboratory tests.
5. The test result is assessed as positive (presence of H. pylori) or negative (no presence of H. pylori).
