RNTCP UPDATE:
To use the test, a technician adds a small sample of a patient’s sputum to a plastic test cartridge and loads it into the machine. The instrument then automatically performs a series of steps that ultimately leads to an analysis of DNA from bacteria in the sample. A computerized printout reports the presence of TB bacteria and whether or not the bacteria are resistant to RIF
In addition, a single MTB/RIF analysis detected TB in over 72% of patients who did not appear to have TB according to smear microscopy but who were later found to have TB in culture tests.
The scientists note that the MTB/RIF test makes it possible to detect TB and drug resistance in a single clinic visit and perhaps begin treatment immediately, a significant advantage in developing countries.
