Methicillin Resistant Staphylococcus Aureus Culture Screen

Test Code: 90417

CPT Code: 87081

Methodology: Chrom Aagar method

Reference Range(s): No Methicillin Resistant Staphylococcus aureus (MRSA) isolated.

Clinical Significance: MRSA is a major cause of nosocomial and life-threatening infections. Infections with MRSA have been associated with a significantly high morbidity, mortality and cost. Selection of these organisms has been greatest in the health care setting. However, MRSA has also become more prevalent in the community.
