Genital herpes is a sexually transmitted infection by the herpes simplex or cold sore virus. It can be transmitted during vaginal, anal or oral sex resulting in painful blisters (cold sores) on the genitals.
If you have herpes in the genital area then the virus will normally shed in your urine and can be detected using PCR technology which is the test used by The Doctors Lab. If the virus is active and showing symptoms like small blisters, the test is able to give a positive result. If you have no symptoms and the virus is present but inactive the test will not give a positive result.
Where symptoms are present in the form of blisters or sores, it is better to have a symptomatic lesion test where you can swab the affected area and test for the presence of the herpes virus.
Bacterial vaginosis, also known as gardnerella vaginalis, mainly affects sexually active women although it can be found in non-sexually active women who disturb the natural balance of bacteria in the vagina due to overuse of feminine hygiene products and heavily scented soaps.

If left untreated the infection can cause serious health complications such as miscarriage or pelvic inflammatory disease.
Trichomonas vaginalis is caused by a tiny single-celled parasite that is transmitted during sexual activity. It’s more common in women than in men but up to half of all men and women have no symptoms but if any develop, it’s usually within a month of infection.

Men may have a thin white discharge from the penis and pain while urinating. The complications of TV are rare but if left untreated it may make it easier for you to become infected with other STIs; including HIV. Also, pregnant women with this infection may have a premature birth or a baby with low birth weight.
