Advantages of TB Diagnostics through Culture methods are as follows:
- Used for testing both the pulmonary & Extra-pulmonary Tuberculosis (EP-TB) specimens for drug susceptibility to first as well as second-line anti-TB drugs
- Used to monitor response to treatment and for long-term follow-up
- Have higher sensitivity and specificity than the molecular testing for TB; referred to as Gold Standards
- Useful in identifying live bacteria during treatment follow-up of Drug-resistant TB (DR-TB) cases, where genotypic methods may prove misleading
Limitations of TB Diagnostic through Culture Methods are as follows:
- Turnaround time for cultures for TB diagnosis is longer than the molecular testing for TB
- There is a higher rate of contamination in liquid culture
- Cannot be maintained at all levels of the healthcare system as specialized labs are required for them
- They require a sophisticated laboratory with expensive infrastructure and laboratory equipment along with trained microbiologists
