Test Code ZG364 MRSA Screen PCR

Important Note

This test is strictly a screen for suspected Methicillin-Resistant Staphylococcus aureus (MRSA) carriers.  No other organisms will be identified, and drug susceptibilities will not be performed if MRSA is detected.  If identification of other potential pathogens is required, or MRSA drug susceptibilities are needed, order the appropriate source-specific culture such as CXWND Wound Culture, or CXRES Respiratory Culture, Bacterial.
