Combined use of the BinaxNOW Staphylococcus aureus test with the Clearview PBP2a assay for the early detection of methicillin-resistant S. aureus from positive blood cultures

Diagn Microbiol Infect Dis. 2014 Mar;78(3):226-8. doi: 10.1016/j.diagmicrobio.2013.11.018. Epub 2013 Nov 27.

Abstract

The use of combination 2 novel immunochromatographic assays for same-day detection of methicillin-resistant Staphylococcus aureus (MRSA) from positive blood cultures was evaluated. Compared to the standard culture methods, the BinaxNOW® S. aureus test demonstrated 98.7% sensitivity and 100% specificity in correctly identifying S. aureus. The sensitivity and specificity of the Clearview® PBP2a assay in differentiating MRSA from methicillin-susceptible S. aureus were 97.1% and 100%.
