Transcription mediated amplification (TMA).
Detection of Chlamydia trachomatis and 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.
Tuesday-Friday and Sunday TAT 1 day
Specimens received on Friday or Sunday afternoon TAT 2 days

Use the APTIMA Unisex Swab Collection Kit. 1. Insert the small, blue shaft collection swab (NOT the larger white shaft cleaning swab) approximately 3-5 cm into the rectum. Rotate swab against the rectal wall at least 3 times. 2. Withdraw the swab carefully. Swabs that are grossly contaminated with feces should be discarded and the collection repeated. 3. Remove the cap from the swab specimen transport tube and immediately place the swab into the transport tube. 4. Carefully break the swab shaft at the score line. 5. Re-cap the swab specimen transport tube tightly and label with two identifiers. Store and transport at room temperature or refrigerated (up to 30 days).
A combined assay for simultaneous detection of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) is used. Individual CT and NG test options are not available. If either CT or NG is requested, both assays will be performed, reported, and billed.
