HELICOBACTER PYLORI TEST

Product detailed description

Helicobacter pylori (H. pylori) is a bacterium that colonizes the lining of the stomach. In some people, it can cause chronic inflammation of the stomach (gastritis), gastric or duodenal ulcers, stomach pain, bloating, heartburn, or other digestive problems. Long-term infection may also be associated with an increased risk of certain stomach diseases.

To detect the presence of this bacterium, we offer two laboratory testing methods.

Blood test – IgA and IgG antibodies

This test detects IgA and IgG antibodies against Helicobacter pylori in the blood.
These antibodies are produced by the immune system as a response to contact with the bacterium.

A blood test can help determine whether the body has been exposed to the bacterium or is likely infected. It is particularly useful as a screening test when Helicobacter pylori infection is suspected.

However, it is important to note that antibodies may remain in the blood even after the infection has been successfully treated, which means that a blood test alone may not always clearly distinguish an active infection.

Stool test – Helicobacter pylori antigen

The stool test detects the antigen of Helicobacter pylori directly in a stool sample.

This test identifies the current presence of the bacterium in the digestive tract, making it especially useful for:

• confirming an active infection

• monitoring the success of eradication therapy

Unlike antibody testing, it detects the actual presence of the bacterium at the time of sampling, rather than only the immune response.

Which test should you choose?

Blood test (antibodies) – suitable as an initial screening test.

Stool test (antigen) – more accurate for confirming an active infection or checking treatment success.

Both tests are simple and non-invasive and may help clarify the cause of long-term stomach or digestive problems.
