Chlamydia trachomatis RNA, TMA, Urogenital Test
This urogenital test measures whether Chlamydia trachomatis RNA is present in the sample submitted, using Transcription-Mediated Amplification (TMA). Chlamydia trachomatis is a bacterium responsible for a common sexually transmitted infection.
About this test
The test can be run on several types of urogenital specimens: a vaginal swab, an endocervical or urethral swab, urine, or a liquid cytology sample collected in ThinPrep® PreservCyt® or SurePath™ preservative. Quest analyzes the sample using Transcription-Mediated Amplification, a method that identifies the organism's RNA rather than growing it in culture.
Because the test looks for genetic material from Chlamydia trachomatis directly, the type of specimen submitted can vary depending on how and where it is collected. The result reports whether Chlamydia trachomatis RNA was identified in the sample provided, and that result is read by the ordering clinician alongside the reason testing was requested.

Additional details
What this test looks at
The test reports whether Chlamydia trachomatis RNA is identified in the urogenital specimen submitted, using Transcription-Mediated Amplification. Quest also lists this test as CT Aptima® or CT TMA, both referring to the same amplification-based method for this organism, run on the Hologic platform.
Order online and a physician order is included — no doctor's visit and no insurance needed. Your sample is collected at a Quest Diagnostics patient service center.

Frequently asked questions
What does this test measure?
It measures whether Chlamydia trachomatis RNA is present in a urogenital specimen, using Transcription-Mediated Amplification (TMA).
How is the sample collected?
The test accepts several specimen types: a vaginal swab, an endocervical or urethral swab, urine, or a liquid cytology sample in ThinPrep® PreservCyt® or SurePath™ preservative.
Do I need to prepare for this test?
Do not urinate for 1 hour before collection, and if you are female, do not cleanse the labial area before collection.
Is this the same as the CT Aptima® test?
Yes. Quest lists this test under names including CT Aptima® and CT TMA, which refer to the same Transcription-Mediated Amplification method used to identify Chlamydia trachomatis RNA.
What does a Chlamydia RNA, TMA test cost without insurance?
$65. Celio Health's price is a flat cash price and insurance is never billed: the required physician's order is included.
Do I need to prepare for this test?
Do not urinate for 1 hour before collection. If you are female, do not cleanse the labial area before collection. This is the preparation Quest publishes for this test; if your clinician gives you different instructions, follow theirs.
