Search Links: General Info : Protocols : LabTestsOnline

DescriptionChlamydia trachomatis causes a sexually transmitted disease (STI) which is also known as the "silent" disease because 50% of infected men and 75% of infected women are asymptomatic. Up to 40% of infected women can develop short- and long-term complications ranging from PID to infertility. It can cause rectal infection in those who have receptive anal intercourse. Neonatal eye disease due to chlamydia trachomatis occurs around 5-14 days post-partum in approximately 50% of children born to infected mothers. N. gonorrhoea is the causative agent of gonorrhoeal disease. The majority of gonorrhoeal infections are uncomplicated lower genital tract infections and may be asymptomatic. However, if left untreated in women, infections can ascend and cause PID. PID can manifest as endometritis, salpingitis, pelvic peritonitis, and tubo-ovarian abscesses. A smaller percentage of persons with gonococcal infections may develop Disseminated Gonococcal Infection (DGI). Trichomonas vaginalis (TV) is the most common curable sexually transmitted disease (STD). Infections in women cause vaginitis, urethritis, and cervicitis. Discharge and small hemorrhagic lesions may be present in the genitourinary tract. Complications can include premature labor, low-birth-weight offspring, premature rupture of membranes, and post-abortion or post-hysterectomy infection. An association with pelvic inflammatory disease, tubal infertility, and cervical cancer with previous episodes of trichomoniasis has been reported.
Indication STI testing for Chlamydia and Gonorrhoea should be offered to all patients under 25 years of age or sexually active. Trichomonas vaginalis testing should only be requested on symptomatic patients where there is a strong suspicion of infection. Where appropriate follow the pH testing pathway set up on ICE Order Comms.
Additional InfoAll samples are tested routinely for both Chlamydia trachomatis and Neisseria gonorrhoea. Please indicate in clinical details if either test is specifically not required
