To check for the presence of H. pylori infection in the body, a carbon 13 or carbon 14 breath test is required, rather than a urine test. The breath test is a non-invasive test with a high accuracy rate and does not require an electronic gastroscopy, so the patient’s compliance is better. For the urine test is mainly for people who have symptoms of urinary discomfort, such as frequent urination, urinary urgency, painful urination, burning sensation, etc. Only then do you need to do a routine urine test, you need to consult a urologist for details. The first choice for H. pylori screening is the breath test, and you can also choose to draw venous blood for H. pylori antibodies, but its accuracy rate is not high. People with H. pylori infection should consult a gastroenterologist and be treated with medication if necessary under the guidance of a specialist.
