Helicobacter Pylori Test
Stool tests are relatively accurate for H. pylori infection.
Stool tests are usually performed using a monoclonal stool antigen test, which detects the presence of H. pylori antigens in the stool to determine the presence of H. pylori infection. This method is highly accurate, with a specificity and sensitivity of more than 90%. In addition, fecal testing can be used to monitor the effectiveness of treatment for H. pylori infection, as well as to evaluate patients for recurrence.
It is important to note that fecal tests are not 100% accurate, and the results may be affected by a variety of factors, such as improper sample collection, patient dietary habits, and drug use. Therefore, for positive stool test results, a comprehensive judgment should be made in conjunction with other test results and the patient's clinical manifestations.
Meanwhile, for patients who have been diagnosed with H. pylori infection, treatment should be carried out according to the doctor's advice and follow-up examinations should be conducted at the end of the treatment to ensure a complete cure.
