Understanding Your Results
Sensitive
Ofloxacin is likely effective against the TB bacteria. May be used in treatment regimen.
Action: Consult physician for appropriate dosage and treatment plan.
Intermediate
Reduced susceptibility to Ofloxacin. Clinical efficacy may be uncertain.
Action: Physician may consider higher doses or alternative antibiotics.
Resistant
Ofloxacin is not effective against the TB bacteria. Alternative antibiotics are needed.
Action: Avoid Ofloxacin and consult physician for other options.
If you experience symptoms like persistent cough, fever, or weight loss, or if you have known TB and need guidance on treatment based on sensitivity results.
Limitations
- ⚠Requires a pure culture of Mycobacterium tuberculosis, which may take time to grow
- ⚠Results are specific to Ofloxacin and may not reflect sensitivity to other antibiotics
- ⚠Does not detect TB directly from clinical specimens without prior culture
Risks & Considerations
- ●Minimal risk associated with sample collection if done properly
- ●Potential for false results due to sample mishandling
Interfering Factors
- ●Improper sample collection or storage
- ●Contamination during culture process
- ●Previous antibiotic treatment may affect results
