title: Extra pulmonary tuberculosis: rapid identification of Mycobacterium tuberculosis grown in Mycobacterium growth indicator tube 960 and Lowenstein-Jensen media, employing Standard diagnostics Bioline Mycobacterium tuberculosis protein 64 antigen detection kit.
abstract: BACKGROUND
  Investigation of extra pulmonary tuberculosis (EPTB) in and around Pondicherry is being carried out since August 2011 in our tertiary care super specialty hospital.
  
  
  OBJECTIVE
  To compare the rapid Kit SD Bio-Line MPT 64 Ag with conventional and time consuming biochemical tests. Confirmation of Mycobacterium tuberculosis at a reasonable time frame is the main thrust.
  
  
  METHODS
  Thirty three Mycobacterium tuberculosis and four Non-Tuberculous Mycobacteria (NTM) grown in MGIT960 system/Lowenstein-Jensen media (LJ) were examined by the rapid MPT 64 antigen detection as well as a battery of conventional tests like niacin, nitrate reduction, paraminobenzoic acid susceptibility and cord formation.
  
  
  CONCLUSIONS
  . Both the rapid kit and conventional tests correctly identified 33 M.tuberculosis isolates. Keeping conventional identification as reference, sensitivity and specificity for rapid kit was 100%. Rapid kit which takes only 15 minutes is accurate, cost effective, and facilitates early treatment for these EPTB patients, whose clinical specimens are paucibacillary.
