At UWHC, a Pre-Surgical screen consists of collecting both left and right nares using one DOUBLE culture swab (CS#4005445).
This test detects both MRSA and MSSA. For MRSA only testing, see MRSA by PCR.
This assay can not detect MSSA if MRSA is present.
This test was performed using a modification of an FDA approved method. The performance characteristics of this test were determined by the UWHC Clinical Laboratories and meet the standards for clinical testing.
Negative results may occur from improper specimen collection, handling or storage, presence of inhibitor or because of the number of organisms in the specimen is below the analytical sensitivity of the test.
A positive test does not necessarily indicate the presence of viable organisms.
