HELICOBACTER PYLORI AB IGA, IGG

Test Code
HPYAG
 
This test is no longer available.

The American College of Gastroenterology no longer recommends serology for detection of H. pylori infection. A positive serology only determines that a patient has been exposed to H. pylori at some time in the past, but not whether the patient is currently infected. Studies indicate that about half of persons with a positive H. pylori serology do not have active infection (ACG,2007). Moreover, serology cannot be used to show that H. pylori have been successfully eradicated after treatment, as antibody levels commonly remain elevated for months to years after treatment.

The Urea Breath Test (UBT) and stool antigen test are recommended by both the American Gastroenterological Association (AGA) and the American College of Gastroenterologists (ACG) as the preferred non-invasive tests for diagnosis and confirmation of eradication. Both methods are highly sensitive and specific and useful for diagnosis therapeutic monitoring, and test of cure. Test Codes for recommended alternative tests: HPBTAD- H. pylori Breath Test, Adult; HPBRT- H. pylori Breath Test, Pediatric (ages 3-17); HPSEIA- H. pylori Antigen, Stool
