Objective: The study objective was to investigate Chlamydia trachomatis (CT) testing patterns, prevalence, and incidence among men and women in Sør-Trøndelag county, central Norway, 1990–2003.

Goal: The goal of this study was to obtain data for recommendations regarding CT screening.

Study Design: Laboratory data on CT tests for persons 15 to 24 years old were retrieved and analyzed.

Results: Four percent of men and 44% of women had been CT tested at least once by the age of 20. By the age of 25, 44% of men and 84% of women had been tested. Prevalence at first test was at its peak in 2000–2002 (men: 15–19 years 18%, 20–24 years 23%; women: 15–19 years 11%, 20–24 years 9%). Incidence estimates were higher for persons with a positive first test than for persons with a negative first test.

Conclusions: More men and more female teenagers need to be tested. Repeat testing is particularly important among people who have been diagnosed with CT.
