February 2020—The FDA authorized marketing of the Cobas VivoDx MRSA (Roche Molecular Systems) diagnostic test based on bacterial viability and novel technology to detect methicillin-resistant Staphylococcus aureus bacterial colonization.
The Cobas VivoDx MRSA test uses a new bacteriophage technology based on bioluminescence to detect MRSA from nasal swab samples in as few as five hours compared with 24 to 48 hours for conventional culture. The FDA reviewed data from performance studies in which the Cobas VivoDx MRSA test correctly identified MRSA in approximately 90 percent of samples where MRSA was present and correctly identified no MRSA in 98.6 percent of samples that did not have MRSA present.
