  • About this test

    The Sexually Trasmitted Infenctions (STI) test detects the genetic material (DNA) of multiple causes of infection of the genital tract and that are potentially associated with sexual transmission. The panel targets the organisms that cause all the sexually transmitted infection syndromes, including genital discharge, genital ulceration, urethritis and pelvic inflammatory syndrome. It also covers causes of vaginitis, cervicitis and syphilis.

    The organisms included in the test are:

    • Trichomonas vaginalis
    • Mycoplasma genitalium
    • Ureaplasma urealyticum
    • Treponema pallidum (Syphilis)
    • Herpes Simplex Virus (HSV) Type 1 and 2
    • Chlamydia trachomatis
    • Neisseria gonorrhoea

    Once the test is positive there is a likelihood of exposure and in the presence of genital symptoms; discharge, itchiness, pain, frequent urination targeted treatment is indicated. In the absence of symptoms there is a chance that the infection has cleared and that the dead organism DNA is still detected. This will also happen if follow-up testing is performed to look for clearance within a period of 3 months.

    In addition to the STI screening, it is also important to test for the Human Immunodeficiency Virus (HIV) which is also a common co-infection.

    Who is this test for?

    The STI test is often ordered in the following scenarios:

    • Screening of sexual partners at the onset of a new relationship
    • High risk behaviour or encounters with possible exposure
    • Follow-up testing after 3 months following completed treatment
    • Symptoms of genital infection: discharge, itching, pain and frequent urination
    • HIV infected individuals, as the virus promotes co-infection with these pathogens
