Both tests use DNA amplification technology to multiply chlamydia-specific DNA from the urine. Chlamydia is then easily detected from the millions of DNA copies which result. They can detect chlamydia from a single bacterium, while older tests need a minimum of 10,000 bacteria. Convenient, non-invasive, and painless. Previous chlamydia tests required cell specimens from swabs inserted into the male urethra, or into the cervix during a pelvic exam.
Urine tests require no special procedures.
Faster and conducive to non-clinic settings. Since taking a urine sample doesn't require a pelvic exam for women, these tests can performed almost anywhere. Large groups of people can be screened in a short time. Some other clinics also offer these tests. Many programs and clinics offer these services to teens confidentially and at no or very low cost.
