RealTime CT
Description
The Abbott RealTime CT assay is an in vitro polymerase chainreaction (PCR) assay for the direct, qualitative detection of theplasmid DNA for C. trachomatis in female endocervical or vaginal swab specimens, male urethral swab specimens, or in male and female urine specimens.

Abbott RealTime CT Comparison Study to Comparator Assay
A total of 623 specimens including female endocervical and vaginal swabs,male urethral swabs, and male and female urines were obtained frompatients attending STD clinics. The swab specimens were alwayscollected first with the comparator assay collection kit and then withthe Abbott multi-Collect Specimen Collection Kit.

Design
Development Philosophy
Today's clinical molecular diagnostics laboratory must have confidence in the quality of their C.trachomatis patient results. As a result of our real-time PCRdevelopment philosophy, Abbott RealTime CT is engineered to be bothsensitive and specific for the detection of C. trachomatis from asingle sample.
Accurate Detection of CT is Dependent Upon a Combination of:
- Primer and Probe Design
- Sample Purification
- Incorporation of an Internal Control
