Overdiagnosis of Clostridium difficile infection in the molecular test era.
This study determined the natural history and need for treatment of patients who are toxin immunoassay negative and polymerase chain reaction (PCR) positive (Tox−/PCR+) for Clostridium difficile Infection ( CDI). They found that among hospitalized adults with suspected CDI, virtually all CDI-related complications and deaths occurred in patients with positive toxin immunoassay test results.

Evaluation of multiple real-time PCR tests on nasal samples in a large MRSA surveillance program.
The researchers evaluated the LightCycler MRSA Advanced Test (Roche Molecular Diagnostics, Pleasanton, CA), the BD MAX MRSA assay (Becton Dickinson, Franklin Lakes, NJ), and the Xpert MRSA assay (Cepheid, Sunnyvale, CA) on nasal samples using the same population. Their results suggest that the performance of the three commercial assays is similar.
