STD Screening Test

 

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are infections that are spread primarily through person-to-person sexual contact including vaginal, anal and oral sex. Some STIs may be spread via skin-to-skin sexual contact. The organisms causing STIs can also be spread through non-sexual means such as blood transfer. Some STIs such as chlamydia and gonorrhoeae can also be transmitted from mother to child during pregnancy and childbirth.

Most STI cases are asymptomatic at the very beginning. It takes a long time for those pathogens to develop symptoms. People infected with those pathogens will unconsciously pass the pathogens to their sexual partners. If left unnoticed and untreated, some STIs can lead to serious health problems such as premature labour, still-births, pelvic inflammatory disease, prostate cancer, eye infection in new-born baby, infertility, etc.

Test Method

This test detects a wide range of STI pathogens (including C. trachomatis (CT), N.
gonorrhoeae (NG), M. genitalium (MG), M. hominis (MH), U. urealyticum (UU), U.
parvum (UP) and T. vaginalis (TV) by real time polymerase chain reaction.
