This study was planned to compare the adenosine deaminase (ADA) levels and polymerase chain reaction (PCR) in cerebrospinal fluid (CSF) as a rapid method to diagnose tuberculosis meningitis (TBM). Fifty-four adult patients with suspected TBM and 37 controls were included in this study. The median ADA level was 21 U/L of most likely TBM, 14 U/L of unconfirmed TBM and 5 U/L of controls. PCR for Mycobacterium tuberculosis was positive in 12 out of 27 most likely TBM cases, 5 out of 27 unconfirmed TBM cases and 3 out of 37 controls. Using a cut off level of >10 U/L, CSF-ADA had a sensitivity of 92.5% and specificity of 97% for the diagnosis of TBM. PCR for M. tuberculosis had a sensitivity of 44.5% and specificity 92% in the most likely TBM cases. This study shows that CSF-ADA is a more sensitive indicator than PCR for the diagnosis of M. tuberculosis.
