Test Parameters & Specifications
Sample Stability
- Contaminated or leaking samples
- Samples without proper labeling or documentation
- Non-viable or insufficient sample volume
- Specimens stored beyond stability limits
Understanding Your Results
Sensitive
The bacteria are susceptible to the drug, and it can be used effectively in treatment.
Resistant
The bacteria are not susceptible to the drug, and alternative medications should be considered to avoid treatment failure.
Intermediate
May require higher doses or combination therapy; consult with a healthcare provider for interpretation.
Consult your doctor immediately after receiving results to discuss treatment options, especially if resistance is detected. Regular follow-ups are essential for monitoring treatment efficacy.
Limitations
- ⚠Results take 2-3 weeks due to slow culture growth
- ⚠Requires pure growth of Mycobacterium tuberculosis complex, which may not always be obtainable
- ⚠May not detect all resistant strains if bacterial load is low
- ⚠Not suitable for rapid diagnosis; consider other tests like GeneXpert for immediate results
Risks & Considerations
- ●Minimal risks associated with sputum collection, such as mild discomfort or coughing
- ●No significant risks from the test itself, as it is a laboratory analysis
Interfering Factors
- ●Contaminated sputum samples
- ●Improper sample collection or storage
- ●Recent use of antibiotics that may suppress bacterial growth
- ●Non-tuberculous mycobacteria interference
