Helicobacter Pylori, technical only
Use
H. pylori organisms cause gastritis. When left untreated, H. pylori gastritis can lead to complications such as ulcers, atrophy, metaplasia, gastric cancer, and MALT lymphoma. Technical component only. Pathologist read not included.
Special Instructions
Fresh Tissues: Specimens may be fixed in formalin for 24-72 hours by collection sites, then transferred to 70% ethanol and stored at 2-8°C for longer-term storage if needed. Samples must be tested 3 months after placing in ethanol. Unstained slides: Positively charged glass slides required to prevent background staining and prevent tissue loss. Slides should be left unbaked.
Limitations
The test is for technical component only and does not include a pathologist's read. Specimens must be fixed in 10% NBF or B plus; all other fixatives will be rejected. The performance of the test might be affected by the type and duration of fixation and storage conditions.
