Helicobacter pylori testing is required for work and vice versa. This is because a health license to test for H. pylori means that the test for H. pylori will be done when the health license check is performed. If the job requires a H. pylori test, then this test is usually required when getting a health certificate. This is because H. pylori is a bacteria that is harmful to the stomach and can lead to diseases such as gastritis, stomach ulcers, and stomach cancer. By testing for H. pylori during a health certificate examination, this bacterial infection can be detected and treated in a timely manner to protect an individual's health. If the job requirements do not mandate the need for H. pylori testing, then this test is usually not required for the health certificate.
