DNA Amplification by Strand Displacement Amplification
Detection of Neisseria gonorrhoeae in male or female rectal specimens.
Adequate specimen collection is important. Mucoid specimens may cause inhibition of the assay. Some feminine sprays, powders, spermicidal agents, and lubricants may interfere with the assay and should not be used prior to specimen collection. A negative result does not exclude the possibility of infection. Predictive value of test will vary depending on disease prevalence. Nucleic acids may persist for up to 4 weeks following appropriate antimicrobial therapy.
A single swab from a rectal specimen can be used for both Chlamydia trachomatis and Neisseria gonorrhoeae DNA amplification. Swab rectal 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.
A single swab can be used for both Chlamydia trachomatis and Neisseria gonorrhoeae DNA Amplification if both tests are requested. Transport tubes will be held for 1 week. Additional testing for Chlamydia trachomatis may be requested by contacting the MLabs Client Services Center.
