**H. pylori IgA antibodies test** measures the presence of Immunoglobulin A (IgA) antibodies in the blood, which are produced by the immune system in response to an infection caused by *Helicobacter pylori*. This bacterium infects the stomach lining and is associated with conditions like peptic ulcers, chronic gastritis, and in some cases, gastric cancer. The test helps detect active or recent H. pylori infection. IgA antibodies typically indicate ongoing or recent infection since they diminish after the infection resolves or is treated. It’s often used alongside IgG and IgM antibody tests or other diagnostic methods like stool antigen tests or urea breath tests for confirmation. ### Clinical Uses: - Diagnosis of H. pylori infection. - Evaluating the cause of persistent gastric symptoms (e.g., bloating, acidity, nausea). - Monitoring eradication therapy success. **Limitations:** IgA levels may not rise in all patients, especially those with weakened immune systems, making additional tests necessary for a complete diagnosis.
