Yes, Helicobacter pylori (H. pylori) can be tested using a blood test, which detects antibodies to the bacteria. However, this method may not be as reliable for diagnosing an active infection, as antibodies can remain in the bloodstream even after the infection has been cleared. Other testing methods, such as breath tests or endoscopic biopsies, are often preferred for more accurate diagnosis.
