Testing for chlamydia, gonorrhoea and Mycoplasma genitalium at Open House

Open House has extensive experience diagnosing, managing and treating chlamydia, gonorrhoea and Mycoplasma genitalium. Our tests, completed with the PCR technique, are unbeatable due to their sensitivity and turnaround time for results.

You can get tested for chlamydia, gonorrhoea and Mycoplasma genitalium after two weeks of the at-risk contact that you want to monitor, unless you have symptoms consistent with infection, by coming into our clinics in Madrid or Valencia for these tests or using our remote services, starting at €80.

Testing for gonorrhoea, chlamydia and Mycoplasma genitalium at Open House:

We perform these tests using the PCR technique, which seeks the DNA of these bacteria and has been shown to be more precise and provide faster results than other techniques. You can get results back in 2 hours with our individual processing system, or in 24-48 hours if we process the tests at our central laboratory. The sensitivity of the tests in genital samples is around 99%, and for throat and rectal samples it is 90%.

Gonorrhoea and chlamydia are the most common sexually transmitted infections, and they are transmitted through unprotected vaginal, anal or oral sex or through contact with the semen, vaginal fluids or anal discharge of infected persons. However, once they are detected, they are easily treatable with antibiotics.

Over the last several years, there has been increasing discussion regarding the role of another bacterium, Mycoplasma genitalium, in urethritis, cervicitis and proctitis not caused by gonorrhoea or chlamydia.


• Chlamydia: Often asymptomatic, but in some cases, there may be pain when urinating or abnormal fluids in the vagina, penis or anus.

• Gonorrhoea and Mycoplasma genitalium: The most common symptoms are burning when urinating, pain during sex and genital and rectal discharge.

• Many people infected with chlamydia, gonorrhoea or Mycoplasma genitalium have no symptoms; if you have had at-risk contact, the only way to rule out these infections is to get tested

Routes of transmission
  • The most common route of transmission for chlamydia and gonorrhoea is oral sex (based on our experience at Open House), as it is almost never performed using protection. Given that these infections mainly occur without symptoms, they are the two main infections that we detect.

    • With regard to Mycoplasma genitalium, it is transmitted through unprotected vaginal or anal penetration. Its possible transmission through oral sex is still being studied, but at this time it has not been proven.


Treatment and prophylaxis
  • Open House meets the national and European requirements for the treatment of chlamydia and gonorrhoea. We choose the appropriate antibiotic based on the location of the infection. Our success rate is 99.5%.

    • Mycoplasma genitalium is a more difficult bacterium to treat; if we perform the test at Open House, the results will show us if the bacterium is resistant or not to a specific antibiotic. If the test is performed at our central laboratory, we treat this bacterium based on the recommended treatment in accordance with the major organisations in the field.

    • If you have had sex that puts you at risk for chlamydia and gonorrhoea in the last 3 days, we can administer prophylactic antibiotics against these infections. However, this option is not appropriate for everyone and is decided on a case-by-case basis. Please contact us to see if you meet the requirements.

Other genitourinary infections

There are other infections that can cause symptoms similar to gonorrhoea, chlamydia and Mycoplasma genitalium, but these are not regularly included in the tests, as it is only recommended that they be identified and treated if the patient has symptoms.

• Mycoplasma hominis and Ureaplasma urealyticum: If these infections are asymptomatic, they never harm men or women, in many cases they are not even treated when they are detected, as they are considered normal bacterial flora. We find these bacteria in 30% of the adult population (in the vagina and urethra) and their route of transmission is exclusively vaginal sex.

• Trichomonas vaginalis: This is an infection caused by a parasite that is silent in 50% of cases. When symptoms are present, they can include vaginal itching or, in men, a burning sensation in the urethra.

• Lymphogranuloma venereum: This is produced by a very aggressive strain of chlamydia and is detectable using tests. As in other chlamydia infections, there are people who are asymptomatic carriers of the disease. This disease is particularly relevant in men who have sex with other men and who practice fisting or who are HIV positive.

• Do you have symptoms? We’ll expand the testing: As you have already read, when someone has symptoms after unprotected penetration, there are other relevant infections. In this plan, we’ll check for the DNA of chlamydia, gonorrhoea, Mycoplasma genitalium, Mycoplasma hominis, Ureaplasma and Trichomonas using the PCR technique. Results are received within 24-48 business hours.
