Biohazard Infectious

Clinical System Name

MRSA PCR Surveillance Only

Synonyms

Methicillin Resistant Staphylococcus aureus

MRSA Screen

 

Description

The MRSA PCR Surveillance Only test is for rapid detection of Staphylococcus aureus (SA) and methicillin-resistant Staphylococcus aureus (MRSA) from patients at risk for SA colonization.

 

Patients admitted to one of the Intensive Care Units are screened for MRSA at time of admit. The MRSA admission screen is included in the ICU admission order set. These orders are generated by a Pathnet rule at time of admission to the ICU. It is not necessary for the provider to order a MRSA Surv PCR for this purpose, because the test is ordered automatically.

Sample Requirements

Specimen: Samples from various body sites are appropriate for MRSA PCR including: axilla, nose, NP, perineum, trach, and throat. Generally 3 separate swabs from 3 different sites are submitted for screening. Each swab should be clearly labeled with the site of collection. Samples should be collected on a BD ESwab. Tracheal aspirates are submitted in the sterile container used for collection. See "Policies and Procedures" on CHILD for additional information about MRSA sample collection.
