Chlamydia diagnosis typically involves a simple laboratory test. Healthcare providers often use a urine sample or a swab from the affected area, such as the cervix or urethra, to detect the presence of the Chlamydia trachomatis bacteria. These tests are quick and can provide results within a few days. In some cases, healthcare professionals may recommend screening for Chlamydia even if no symptoms are present, especially for individuals at higher risk. Regular testing is important because many people with Chlamydia do not experience noticeable symptoms, which can lead to complications if left untreated.
