Helicobacter pylori blood test and blowing which accurate

H. pylori antibody serology is a test

that detects antibodies in the blood to determine the presence of H. pylori infection. If the antibodies are produced for a long time, they may not detect H. pylori early in the infection. In addition, blood tests cannot distinguish between previous infections and current infections. The H. pylori breath test detects urease produced by H. pylori by taking urea capsules labeled with carbon 13 or carbon 14 and then blowing air. This method has high sensitivity and specificity and can accurately detect H. pylori infection.
