Chlamydia trachomatis and Neisseria gonorrhoeae by Transcription-Mediated Amplification (TMA), ThinPrep

Also known as: CG MATP

Clinical Use

Order Test

Use

This test is used to detect the presence of Chlamydia trachomatis and Neisseria gonorrhoeae in ThinPrep specimens. It is performed using Transcription-Mediated Amplification (TMA), a sensitive nucleic acid amplification technique. The test is intended for medical purposes to diagnose infections but is not suitable for evaluating suspected sexual abuse or for forensic use. Positive results may require confirmation through alternative nucleic acid targets, depending on clinical context and regulatory requirements.

Special Instructions

This test exclusively uses ThinPrep samples and involves transferring specimens into an APTIMA Specimen Transfer Tube to minimize contamination risks. It requires a cervical specimen collected using the ThinPrep Pap Test Collection Kit. Specimen source must be provided when ordering, and samples must be refrigerated during storage and transport.

Limitations

The test does not confirm positive results with an alternative nucleic acid target, which might be necessary per clinical guidelines or legal requirements, especially in cases where culture is required for diagnosis. Inadequate specimen collection, transport, or handling may lead to inaccurate results. The reliability of the test outside its intended use or patient population is not established.
