Abstract
OBJECTIVE: To evaluate the recently available Cobas Amplicor polymerase chain reaction (PCR) system for the detection of Mycobacterium tuberculosis complex (MTBC) in well-characterized clinical specimens and to compare the results with clinical classification, conventional culture and staining techniques.
METHODS: Three hundred and forty-four clinical specimens consecutively received for culture of acid-fast bacilli by the laboratory of Zayed Military Hospital, Abu Dhabi, United Arab Emirates, from 2004 to 2005, were used in this study. Acid-fast bacilli and culture for tuberculosis were compared with Cobas Amplicor PCR.
RESULTS: The final diagnostic evaluation of the Cobas Amplicor MTB showed the followings: sensitivity 73.3%, specificity 99.4%, positive predictive value 84.6%, negative predictive value 98.8% and with accuracy of 98.2% for the Cobas Amplicor MTB assay.
CONCLUSION: The automated Cobas Amplicor MTB assay is suitable for routine use in clinical laboratories.
