Specimen Requirements

A single swab from a urogenital specimen can be used for both Chlamydia trachomatis and Neisseria gonorrhoeae DNA amplification. Swab oral site. Insert the swab all the way into the transport media immediately after specimen collection and bend the shaft of swab against the tube to break shaft; it is scored to break easily if the swab is inserted completely into transport. TIGHTEN LID OF TRANSPORT TUBE SECURELY TO PREVENT LOSS OF FLUID. The following specimens are unacceptable: white shaft cleaning swabs, wooden swabs, or Calgiswabs.

Alternate Specimen
M4-RT transport is acceptable. M4-RT kits may be stored at room temperature before use but should be refrigerated within an hour of specimen collection. However, constant refrigeration is not critical so it is okay for specimens to be placed in lock box at room temperature until pick up.
This assay should not be used for the evaluation of suspected sexual abuse or for other medico-legal investigations.
