Helicobacter pylori (H. pylori) is a bacterium that colonizes the lining of the stomach. In some individuals, it can cause chronic inflammation of the stomach (gastritis), gastric or duodenal ulcers, stomach pain, bloating, heartburn, or other digestive issues. 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 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 in 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 suitable as a screening test when H. pylori infection is suspected.
However, it is important to note that antibodies may persist in the blood even after a past infection. Therefore, a blood test alone may not always accurately 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 confirms the current presence of the bacterium in the digestive tract and is therefore highly suitable for:
-
confirming an active infection
-
monitoring the success of treatment (eradication therapy)
Unlike the blood test, it reflects the presence of the bacterium at the time of sampling, not just the immune response.
Which Test Should You Choose?
-
Blood test (antibodies) – suitable as an initial screening method
-
Stool test (antigen) – more accurate for confirming an active infection or for post-treatment follow-up
Both tests are simple and non-invasive and can help identify the cause of long-term stomach or digestive problems.
