Also known as: Chlamydia trachomatis, Amplicor® PCR, Chlamydia trachomatis, Aptima® SDA, Chlamydia trachomatis, ProbeTec™ TMA
Use
Detect Chlamydia trachomatis
Special Instructions
Not provided.
Limitations
Test accuracy is dependent on following the correct specimen collection and handling procedures. Inappropriate transport conditions can lead to false results. The test may yield false negatives if the bacterial load is low or if the sample is not properly collected. Samples from sites other than pharyngeal, unlabeled specimens or those with discrepancies, and swabs not supplied by Gen-Probe are the common causes for rejection. Additionally, the test should not be used beyond the collection timeframe of 60 days.

Container
Gen-Probe® Aptima® swab specimen transport tube
Collection Instructions
Use the blue-shafted swab, labeled 'unisex collection swab for endocervical and male urethral specimens,' to rub the posterior pharynx and tonsillar areas. Do not use the white-shafted swab; discard this swab. Remove the cap from the swab specimen transport tube and immediately place the specimen collection swab into the transport tube. Carefully break the swab shaft at the scoreline; use care to avoid splashing of the contents. Recap the swab specimen transport tube tightly.
Storage Instructions
Maintain specimen at room temperature or refrigerate (2°C to 30°C).
Causes for Rejection
Inappropriate transport conditions; bacterial swabs; swabs from sites other than pharyngeal; unlabeled specimens or those with a discrepancy between the specimen label and the request form; Aptima swab transport tube with no swabs, two swabs or swab not supplied by GenProbe; Aptima swabs greater than 60 days from collection; any transport device other than an Aptima swab transport.
