| Abstract | This guidance was developed by the PHLS South West GP Laboratory Use Project Team in collaboration with GPs and experts in the field and is in line with other UK guidance including SIGN and PRODIGY. Genital Chlamydia Trachomatis infection is most common in the younger, sexually active population (20-24 yr old men and 16-19 yr old women). However, infection is asymptomatic in 50% of men and 70% of women. This Quick Reference Guide gives information on testing, sampling and retesting. |
