Special Instructions
For optimal recovery, fresh tissue or body fluid is preferred. If unable to attain ample specimen in a sterile container, a blue Culturette swab may be used.
If the specimen container is a Culturette swab and multiple tests are requested, collect a second swab to maximize test sensitivity.
If the specimen cannot be delivered to the laboratory within 1 hour it should be refrigerated to decrease overgrowth with contaminating organisms.
