Helicobacter pylori IgG Antibody

The Helicobacter pylori IgG antibody test detects the presence of IgG antibodies against H. pylori bacteria in the blood. It helps determine if a person has been exposed to this bacterium, which is commonly linked to stomach ulcers, gastritis, and sometimes stomach cancer. A positive result indicates current or past infection, but it does not distinguish between active and previous infection.

Why consider Helicobacter pylori IgG antibody test?

Helicobacter pylori IgG antibody test is considered when a person shows symptoms of stomach problems like ulcers, chronic gastritis, or unexplained abdominal pain, and H. pylori infection is suspected. It is also used to screen for exposure to the bacteria, especially in patients with a history of peptic ulcers or gastric discomfort. Additionally, it helps guide treatment decisions and monitor response to therapy, particularly when invasive tests are not feasible.

Who should get Helicobacter pylori IgG antibody test done?

• Have symptoms like persistent stomach pain, nausea, or indigestion.
• Are suspected to have peptic ulcers or chronic gastritis.
• Have a history of gastric issues linked to H. pylori infection.
• Need to confirm past exposure to the bacteria when other tests are not available.
• Are undergoing evaluation for risk factors related to stomach cancer.

More Information about Helicobacter pylori IgG antibody Test 

The Helicobacter pylori IgG antibody test can remain positive for months or even years after the infection has been cleared, so it’s not ideal for confirming eradication after treatment. It is less effective in distinguishing between current and past infections compared to other tests like the urea breath test or stool antigen test. In areas with high infection rates, many healthy people may test positive without symptoms.
