title: Evaluation of Copan FLOQSwab for the molecular detection of Chlamydia trachomatis by Abbott RealTime CT PCR.
abstract: OBJECTIVE
  We evaluated Copan FLOQSwabs next to Abbott swabs for the detection of Chlamydia trachomatis (CT) by Abbott RealTime PCR.
  
  
  METHODS
  We collected 1062 paired swabs from female sex workers. The study was divided in two arms, according to the order of swab collection.
  
  
  RESULTS
  If the Abbott swab was collected first, 501 couples were concordant and two discordant (Abbott negative and Copan positive). If the Copan swab was collected first, 537 couples were concordant and 10 discordant (eight Abbott negative and Copan positive and two Abbott positive and Copan negative). All discordant samples contained low levels of C. trachomatis. Technical issues lead to retesting of 64 Copan and 21 Abbott swabs.
  
  
  CONCLUSIONS
  Our results show that Copan FLOQSwabs can be used interchangeably with Abbott swabs. While appearing to have an advantage in detecting more positive samples, the use of Copan swabs led to a higher retesting rate due to technical errors.
