Chlamydia - Pain during urination, pain during intercourse, vaginal/penile discharge

Chlamydia is one of the most common infections today, particularly amongst the 15-24 years age group. Caused by the chlamydia trachomatis infection, the bacteria infect the urethra (urine canal) in men and women, as well as the cervix in women. Untreated chlamydia infection can spread to the fallopian tubes and uterus and cause pelvic inflammatory disease (PID), resulting in long-term infertility, pelvic paid or ectopic pregnancy.

Symptoms

Pain during urination, pain during intercourse, vaginal/penile discharge.

Tests

Two tests are available to check for a chlamydia trachomatis infection:

Chlamydia by PCR and Chlamydia/Gonorrhoea Combination by PCR

Both are urine tests using the accurate PCR testing methodology, and results are available within 2-3 days.

Treatments

Chlamydia treatments include antibiotics such as azithromycin, tetracyclines or erythromycin. Itís also important that partners are also tested and treated to prevent reinfection.

Gardnerella vaginalis (BV) - Vaginal discharge, pelvic pain, vaginal pain/irritation, vaginal itching, foul-smelling discharge

Gardnerella vaginalis is a vaginal infection that is caused by an overgrowth of bacteria. Also known as bacterial vaginosis, this infection is known to affect a third of women in the UK. If left untreated, it can lead to PID and infertility.

Symptoms

Vaginal discharge, pelvic pain, vaginal pain/irritation, vaginal itching, foul-smelling discharge.

Tests

Two tests are available to check for a gardnerella or BV infection:

Gardnerella Vaginalis by PCR and STD8 BV Profile

Gardnerella is a urine test and is processed using the PCR testing methodology, with results in 3-5 days. The STD8 BV Profile test is a DNA swab test which checks for Candida species, Gardnerella vaginalis and Trichomonas vaginalis; results are processed in just 1-2 days.

Treatments

Gardnerella vaginalis (BV) treatments include antibiotics such as metronidazole or Flagyl. Itís also important that partners are also tested and treated to prevent reinfection.

Genital herpes - Painful, red blisters or sores/bumps on or around the genital area

Genital herpes is a viral STI caused by the Herpes Simplex Virus (HSV), specifically HSV type 2. Once infected, the virus can remain dormant in the body for years with only a few outbreaks per year or every few years. Genital herpes can accurately be tested when the virus is in itís active stage Ė ie you are experiencing symptoms of the infection.

Symptoms

Painful, red blisters or sores/bumps that appear on or around the genital area.

Tests

Two tests are available to check for a genital herpes infection:

Herpes Simplex I/II by PCR and STD9 Symptomatic Lesion Sample Using PCR Swab

Herpes Simplex is a urine test and is processed using the PCR testing methodology, with results in 3-5 days. The STD9 Symptomatic Lesion Profile test is a DNA swab test which checks for Syphilis and Herpes Simplex by PCR with a single swab. Results are processed in 3-4 days.

Treatments

Unfortunately this infection cannot be completely cured but antiviral treatments are available to help effectively manage and treat the infection when it does occur. Treatments include suppression with antiviral medication such as aciclovir, famciclovir or valaciclovir, or pain relief medication such as Nurofen. Itís also important that partners are also tested and treated to prevent further outbreaks.

Gonorrhoea - Pain during urination, vaginal/penile discharge. Rare cases: rash or joint pain

Gonorrhoea is a highly contagious STI caused by the Neisseria gonorrhoea bacteria. It can affect the urethra in men and women, as well as the cervix, uterus and fallopian tubes in women. Gonorrhoea can lead to PID or infertility if itís not treated early on.

Symptoms

Pain during urination, vaginal/penile discharge, rarely rash and joint pain.

Tests

Two tests are available to check for a Neisseria gonorrhoea infection:

Gonorrhoea by PCR and Chlamydia/Gonorrhoea Combination by PCR

Both are urine tests using the accurate PCR testing methodology, and results are available within 2-3 days.

Treatments

Gonorrhoea treatments include antibiotics such as a combination of azithromycin and cefixime to treat the more resistant strains of the infection. Itís also important that partners are also tested and treated to prevent reinfection.

Ureaplasma urealyticum - Pain during urination and urethral discharge in men. No symptoms commonly experienced by women

Ureaplasma is a bacterial infection that is most often associated with non-gonococcal urethritis in men. It has also been associated with pregnancy problems in women if left untreated.

Symptoms

Pain during urination and urethral discharge in men. No symptoms commonly experienced by women.

Tests

A single accurate test is available to check for a ureaplasma infection:

Ureaplasma by PCR

This is a urine test using the accurate PCR testing methodology, and results are available within 4-5 days.

Treatments

Ureaplasma treatments include antibiotics such as azithromycin or doxycycline. Itís also important that partners are also tested and treated to prevent reinfection.

Mycoplasma genitalium - Penile discharge and a burning sensation during urination in men, and vaginal discharge, pain during intercourse and rarely a fever or pelvic pain in women

This infection is caused by the mycoplasma genitalium bacteria and is a common STI which often doesnít cause any symptoms. It can lead to urethritis in men or cervical/pelvic inflammation in women if it is not treated.

Symptoms

Often asymptomatic. Penile discharge and a burning sensation during urination in men, and vaginal discharge, pain during intercourse and rarely a fever or pelvic pain in women.

Tests

An accurate test is available to check for a mycoplasma infection:

Mycoplasma Genitalium by PCR

This is a urine test using the accurate PCR testing methodology, and results are available within 4-5 days.

Treatments

Mycoplasma treatments include antibiotics such as a single dose of azithromycin or a 7-10 day course of doxycycline. If PID is already detected, further antibiotic treatment is required. Itís also important that partners are also tested and treated to prevent reinfection.

Trichomonas vaginalis - In women: pain during urination and sex, greenish-yellow or frothy and foul-smelling vaginal discharge, vaginal itching. In men: burning during urination or after ejaculation, penile discharge

A trichomonas vaginalis infection is caused by a protozoa that affects the genitourinary tract. Once contracted, this protozoa usually leads to vaginal infections, causing inflammation (or vaginitis). Men may also become infected through unprotected sex.

Symptoms

In women: pain during urination and sex, greenish-yellow or frothy and foul-smelling vaginal discharge, vaginal itching. In men: burning during urination or after ejaculation, penile discharge.

Tests

A single accurate test is available to check for a trichomonas infection:

Trichomonas Vaginalis by PCR

This is a urine test using the accurate PCR testing methodology, and results are available within 4-5 days.

Treatments

Trichomonas treatments include antibiotics such as metronidazole or Flagyl. Itís also important that partners are also tested and treated to prevent reinfection.
