Why Testing for Chlamydia is Important
Since chlamydia infections are often asymptomatic, especially in the early stages, many individuals may unknowingly have and transmit the infection. Regular screening through laboratory testing is the only reliable way to detect the presence of the bacteria and ensure appropriate antibiotic treatment can be started promptly.
Understanding Your Test Results
A positive result indicates the presence of chlamydia bacteria and requires immediate antibiotic treatment as prescribed by a healthcare provider. Sexual partners should also be tested and treated to prevent reinfection. A negative result means no chlamydia was detected at the time of testing.
Important Considerations
