Helicobacter Pylori ( H Pylori ) IgG & IgA Antibodies

HELICOBACTER PYLORI ( H PYLORI ) IGG & IGA ANTIBODIES Test Purpose

The Helicobacter pylori (H. pylori) IgG & IgA Antibodies test detects antibodies produced by the immune system against H. pylori, a bacterium that can infect the stomach lining.

H. pylori infection is associated with conditions such as chronic gastritis, peptic ulcers, and an increased risk of certain stomach cancers. Testing for H. pylori antibodies may help identify previous or possible exposure to the bacterium.

IgG antibodies can remain detectable for a long time after infection, while IgA antibodies may also develop in response to infection. However, antibody testing generally cannot reliably distinguish an active infection from a previous infection. When active H. pylori infection needs to be confirmed, healthcare providers may recommend tests such as the urea breath test or stool antigen test.

HELICOBACTER PYLORI ( H PYLORI ) IGG & IGA ANTIBODIES Test Recommended for Individuals:

• Individuals with persistent or recurrent upper abdominal discomfort
• People with symptoms suggestive of gastritis or peptic ulcer disease
• Individuals with unexplained indigestion or dyspepsia
• Patients with a history of peptic ulcers
• People being evaluated for possible H. pylori infection
• Individuals advised by their healthcare provider to undergo H. pylori testing

FAQs

1. What does the H. pylori IgG & IgA antibody test detect?
It detects IgG and IgA antibodies against H. pylori, indicating that the immune system has been exposed to the bacteria.

2. Does a positive H. pylori antibody test mean I have an active infection?
Not necessarily. H. pylori antibodies can remain detectable after the infection has cleared, so a positive antibody result cannot reliably confirm an active infection. Additional testing may be recommended.

3. Which tests can confirm an active H. pylori infection?
For active infection, healthcare providers commonly consider a urea breath test or H. pylori stool antigen test. The appropriate test depends on your symptoms, treatment history, and clinical situation.
