- Insufficient sample volume or growth
- Sample received at room temperature beyond 48 hours without refrigeration
Understanding Your Results
Positive for MOTT Growth
Non-tuberculosis mycobacteria detected; consult an infectious disease specialist for appropriate treatment based on susceptibility results.
Negative for MOTT Growth
No slow-growing mycobacteria identified; clinical correlation is advised if symptoms persist, as other causes may be present.
Antibiotic Susceptibility Profile
MIC values indicate the bacteria's sensitivity to antibiotics; use this data to select effective therapy as per clinical guidelines.
Consult a healthcare professional or infectious disease specialist if you have persistent symptoms such as chronic cough, fever, or skin lesions, or if test results indicate an NTM infection for proper management and treatment planning.
Limitations
- ⚠This test is specific to slow-growing mycobacteria; fast-growing species may require different testing methods.
- ⚠Results depend on successful culture, which can take time due to slow growth rates.
- ⚠Does not detect all NTM species; additional tests may be needed for comprehensive diagnosis.
Risks & Considerations
- ●Minimal risk; this test is based on sample submission and does not involve invasive procedures.
- ●Risk of sample contamination if not handled properly, which may affect results.
Interfering Factors
- ●Contamination of the sample with other bacteria
- ●Recent antibiotic therapy that may suppress mycobacterial growth
- ●Improper storage or handling of the sample prior to submission
