General Information
Performed: Daily
Turn Around Time: 3 hours
CPT Codes: 87150
Performed By: Microbiology Lab
Notes: If a patient has a positive MRSA/SA blood culture assay result (MRSA+ or SA+), no more MRSA/SA blood culture PCR assays will be performed on that patient for the next 3 days.
Clinical Utility:
This test will be performed on positive blood cultures (on adult aerobic bottles) if the gram stain indicates gram positive cocci in clusters (GPCC) or gram positive cocci in singles (GPC).
A positive test result does not necessarily indicate the presence of viable organisms. This is presumptive for the presence of MRSA or Staphylococcus aureus.
Negative results indicate Staph aureus DNA not detected; Gram stain result might be representative of other staph species.
The Xpert MRSA/SA Blood culture RT-PCR test is indicated for use in conjunction with other laboratory and clinical data.
