Antral biopsy urease test: Sensitivity and Specificity

Introduction: None written. Excerpt from the entry in Helicobactor pylori:
[sens/spec is per UpToDate]

One reason for lack of specificity: If specifmen contains less common non-pylori gastric helicobacters, which give only weakly positive results in the biopsy urease test. Positive identification of these bacteria requires visualization of the characteristic long, tight spirals in histologic sections.
