The Helicobacter pylori (H. pylori) IgA & IgG test is a blood test that detects antibodies produced by the body in response to Helicobacter pylori infection. 🦠🩸

• IgM/IgA antibodies indicate recent or ongoing infection (mucosal immune response).
• IgG antibodies indicate past or chronic exposure and may persist even after the infection is treated.
• This test is serological, meaning it reflects the immune response, not the presence of live bacteria.
