Understanding Your Results
Confirms E. coli infection. Further analysis of resistance genes guides antibiotic choice.
Indicates carbapenem resistance. Patient may require alternative antibiotics like colistin or tigecycline.
High-risk clone associated with extraintestinal infections and multidrug resistance.
Suggests enteropathogenic E. coli (EPEC) potential, relevant for diarrheal disease.
Consult your healthcare provider if you have persistent or recurrent infections, or if you have been advised this test for diagnosis or management. Discuss the results with your doctor for appropriate treatment.
Limitations
- ⚠Requires high-quality extracted DNA; degraded DNA may yield incomplete results
- ⚠Reference-based analysis may miss novel genes not present in databases
- ⚠Cannot differentiate between live and dead bacteria
- ⚠Results should be correlated with clinical presentation and culture findings
- ⚠Bioinformatics interpretation requires expertise
Risks & Considerations
- ●No significant physical risks as the test is performed on extracted DNA
- ●Possible psychological impact of results
- ●Financial cost of the test
Interfering Factors
- ●Poor DNA quality or quantity
- ●Contamination with host or other bacterial DNA
- ●Incomplete reference databases
- ●Mixed bacterial cultures
- ●Inappropriate sample storage

|---|---|---|---|---|
| Comparison | Bacterial Genome Reference Based Data Analysis-Illumina | Targets a single gene, less comprehensive than whole genome analysis. Cannot detect resistance genes. | Detects specific resistance genes only, not whole genome. Faster but limited. | Assembles genome without reference, more expensive and computationally intensive. Provides novel insights. |
