Laboratory Findings
The diagnosis of Helicobacter pylori can be by:
- Breath testing (does not require EGD);
- Direct culture from an EGD biopsy specimen;
- Direct detection of urease activity in a biopsy specimen;
- Measurement of antibody levels in blood (does not require EGD). It is still somewhat controversial whether a positive antibody without EGD is enough to warrant eradication therapy.
The possibility of other causes of ulcers, notably malignancy (gastric cancer) needs to be kept in mind. This is especially true in ulcers of the greater (large) curvature of the stomach; most are also a consequence of chronic H. pyloriinfection.
