From: Incidence, prevalence, and management of MRSA bacteremia across patient populations—a review of recent developments in MRSA management and treatment

MRSA testing modality Number of studies Sensitivity, % (95% CI) Specificity, % (95% CI)

Chromogenic media, 18–24 h 28 78.3 (71.0–84.1)a,b 98.6 (97.7–99.1)b,c
Chromogenic media, 48 h 24 87.6 (82.1–91.6) 94.7 (91.6–96.8)
PCR 15 92.5 (87.4–95.9) 97.0 (94.5–98.4)
