To explore the cost-effectiveness of five different screening methods for H. pylori infection: 1)endoscopic gastric biopsy and rapid urease test (RUT) + Histology (If RUT is negative) ;2)urea breath test (UBT); 3)serology; 4)stool polymerase chain reaction (PCR); and 5)therapeutic diagnosis

Methods Advantage/Disadvantage
Endoscopic gastric biopsy and RUT (and histology if needed)
The gold standard of H. pylori screening is recommended by the Gastroenterological Association of Thailand
UBTSimple screening method, widely used in developed countries, but not in Thailand due to its high costs (2,500 Baht/case)
Serology Convenient for epidemiological investigation
Stool PCR Complicated sampling techniques which can be inconvenient in clinical practice
Therapeutic diagnosis Based on personal judgment of the physicians
