If a person is believed to have contracted chlamydia, it is advised that he get tested immediately. However, according to the United Kingdom's National Health Service, it may take up to two weeks after sexual activity for the infection to be detected. Chlamydia is one of the most common sexually translated diseases, and it can produce no symptoms, making it difficult to detect.
Chlamydia can be contracted by men and women orally, vaginally or anally. Symptoms usually appear within one to three weeks if they are noticeable. Typical reported symptoms for men, according to WebMD, include painful urination, discharge from the penis that is either clear or cloudy in color, burning or itching around the penis and pain and swelling around the testicles. For women, symptoms include pain during urination, discharge from the vagina that may have an odor, painful periods, abdominal pain, itching or burning around the vagina and pain during intercourse.
WebMD notes that when people get tested for chlamydia, the medical professional typically uses a swab to take a sample from the urethra in males and the cervix in females. The sample is then examined in a laboratory. Some doctors use urine tests to determine if chlamydia is present.
