Special Instructions
Not provided.
Limitations
The test is limited to screening for MRSA colonization and does not diagnose active infection. It may not detect MRSA if colonization levels are low or if the bacteria are inhibited during collection. Delays in specimen transport can affect test results, and specimens outside of proper conditions may be rejected. Alternative tests should be considered for other pathogens or for comprehensive susceptibility testing.
