Common mistakes around Helicobacter Basis

Common mistakes around Helicobacter pylori include: treating without antibiotic resistance testing, using single antibiotics instead of combination therapy, failing to confirm eradication after treatment, and misinterpreting genetic predisposition tests as diagnostic. MyBody-X DNA tests cannot detect active H. pylori infection; they only report genetic variants that may slightly influence susceptibility, which is not clinically actionable. The correct approach is stool antigen or urea breath test for active infection. Another mistake is assuming all carriers need treatment; only those with symptomatic gastritis, peptic ulcer, or high-risk conditions should be treated. Evidence: clinical practice and guidelines.
