Hi, am Maopa from Fiji,
There are 3 DOTs centres in Fiji and all have been provided with GeneXpert. There has not been any MDR TB reported for Fiji. Recently, we ran a geneXpert for a 3+ AFB case with the following result;
1st specimen = MTB Detected High/Rif resistant Positive
2nd specimen = MTB Detected High/Rif resistant negative
3rd specimen = MTB Detected Low/Rif resistant negative
The result gave a confusing status of Xpert result especially with no other confirmation apart from culture and MPT64 done locally. The specimen has then been sent to QMRL, Australia for confirmation and DST.
Can we still trust GeneXpert as a identification tool for MTB and Rifampicin resistant?
