Performance estimates for gonorrhoea showing the sensitivity of the nucleic acid amplification test (NAAT) on a given specimen site relative to patient infection status (PIS). The studies are referenced by the first author, and publication year, and colours are by study for clarity. Each study is represented by a colour and where results are stratified by test, sampling or symptom status, this has been included in the figure. Tests used: LCR (ligase chain reaction); PCR AMP (PCR Ampicor); PCR Cobas CT/NG (PCR Cobas CT/NG); PCR ‘In house’; PCR RealTime (PCR RealTime); qPCR TaqMan (quantitative PCR TaqMan); qPCR DxCT/NG/MG (quantitative PCR DxCT/NG/MG); PCR LightMix, (PCR Lightmix); NASBA (nucleic acid sequence-based amplification); SDA ProbeTec ET (strand displacement amplification Probetec ET); SDA ProbeTec CT/GC Q^x, (strand displacement amplification ProbeTec CT/GC Q^x); TMA AC2 (transcription-mediated amplification Aptima Combo-2); TMA ACT (transcription-mediated amplification Aptima CT); TMA AGC (transcription-mediated amplification Aptima GC).
