Our institution uses a bd max mrsa assay for nasal swab specimens and positive blood cultures with gram positive cocci in clusters.Pt was admitted for a low hemoglobin on (b)(6).Pt was eventually found to have a hemothorax and transferred to the icu on (b)(6).Pt spiked fevers on (b)(6) and blood cultures were obtained that turned positive later that day.Gram stain of blood culture showed gram positive cocci in clusters.The specimen was run on the bd max (b)(4) assay.The assay suggested (b)(6).The icu team switched the pt from vancomycin to nafcillin.Traditional culture and sensitivity later revealed (b)(6).The pt is now under hospice care.
