Is It Best to Take Another Blood Test After Taking Antibiotics for H. Pylori?

It is common practice for doctors to order a retest of those diagnosed with Helicobacter pylori, or H. pylori, bacterium after completing a treatment regimen, according to MedlinePlus. Retesting ensures elimination of the bacterium from the body and dictates the further course of treatment.

Doctors normally order H. pylori testing when a patient presents symptoms of H. pylori infection, also known as peptic ulcer disease, according to MedlinePlus. Additionally, doctors often order testing for the bacterium when a patient has a duodenal or stomach ulcer, or if the patient previously had such an ulcer with no confirmed presence of H. pylori.
