Overview
The purpose of RNA Extraction from Stool is to detect the presence of RNA from pathogens or abnormal cells in the gastrointestinal tract. It helps in diagnosing infectious diarrhea, viral hepatitis, IBD, colorectal cancer, and H. pylori infection. The test is non-invasive, making it a preferred choice for patients who require regular monitoring or have difficulty with invasive procedures.

Test Parameters & Specifications
Sample Stability
- Sample leaked or contaminated
- Insufficient quantity
- Improper labeling
- Sample received after prolonged delay without proper storage
Understanding Your Results
Positive
Indicates presence of target RNA, suggesting infection or disease. Clinical correlation required.
Negative
No target RNA detected. However, this does not rule out infection if clinical suspicion is high.
If you experience persistent abdominal pain, diarrhea, bloody stool, fever, or unexplained weight loss, consult a gastroenterologist. Early diagnosis can prevent complications.
Limitations
- ⚠May not detect all pathogens due to RNA degradation
- ⚠Requires specialized laboratory equipment and expertise
- ⚠Results should be correlated with clinical findings
Risks & Considerations
- ●No significant risks associated with stool sample collection
- ●Minor discomfort during sample collection is unlikely
Interfering Factors
- ●Improper sample collection or storage
- ●Contamination with urine or water
- ●Recent antibiotic use
- ●Presence of PCR inhibitors in stool
