* For 12 out of 10 samples, MRSA was isolated only from TSB with 6.5% NaCl and was not isolated on initial direct culture.


Note: These tables show percent agreement and not sensitivity.

MRSASelect™ is a selective and differential chromogenic medium used for the qualitative detection of methicillin-resistant Staphylococcus aureus (MRSA). With high sensitivity and specificity as well direct identification, the MRSASelect test can identify MRSA in just 18–28 hours using a nasal swab and/or a wound specimen. The test procedure is simple, and results are easy to read and interpret. This process is designed for optimal selectivity.

MRSA is most often spread in patient facilities, and several U.S. states mandate screening for MRSA in hospitals and other healthcare facilities. The detection time of MRSASelect provides healthcare facilities with the ability to implement fast and effective infection control as the key to preventing wide spread MRSA infection.
