The median number of days to obtain a negative chlamydia NAAT was 8 days (IQR 7–14) in pregnant and 7 days (IQR 6–10) in nonpregnant women (WRST p = 0.04). All participants had a negative chlamydia NAAT by day 29 post-treatment.

How long does chlamydia test stay positive after treatment?

Conclusions. If a TOC for anogenital chlamydia is indicated, we recommend performing it at least 14 days after initiation of treatment, when using modern RNA- and DNA-based assays. A positive result shortly after 14 days probably indicates a blip, rather than a treatment failure or a reinfection.
