Test Overview
Transcription mediated amplification (TMA).
Detection of Chlamydia trachomatis and Neisseria gonorrhoeae in male or female urine specimens.
Negative
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
Adequate specimen collection is important. Test should be performed on a first catch random urine specimen. 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.
Test Details
Specimens received Sunday-Thursday 1-day TAT
Specimens received on Friday or Saturday afternoon 2-3 days TAT
- Chlamydia trachomatis RNA Amplification
- CT RNA Amplification
- GC RNA Amplification
- Neisseria gonorrhoeae RNA Amplification
Specimen Requirements
Use the APTIMA Urine Specimen Collection Kit. 1. The patient should not have urinated for at least 1 hour prior to sample collection. Female patients should not cleanse the labial area prior to collection. 2. Instruct patient to provide 20 to 30 mL of the initial urine stream (NOT midstream) into a urine cup free of any preservatives. Collection of larger volumes of urine may result in rRNA target dilution that may reduce test sensitivity. 3. Remove the cap and transfer 2 mL of urine into the Urine Transport Tube using the disposable pipette provided. The correct volume of urine has been added when the fluid level is between the black lines on the urine transport tube label. 4. Re-cap the urine specimen transport tube tightly and label with two identifiers. Store and transport at room temperature or refrigerated. See http://www.pathology.med.umich.edu/handbook/Tables/Aptima_Urine.pdf for collection procedure guide.
Additional Information
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.
