If we are going to look for these infections in your genitals, we can do either rapid or sensitive tests .

  • Our rapid tests
Our rapid tests

Our rapid tests detect specific proteins from the bacteria; they detect more cases than conventional tests used in the Spanish public health system and also only take 20 minutes. Total detection of gonorrhoea and chlamydia infections is about 90%. However, they are only really useful in people with full blown symptoms of gonorrhoea and chlamydia (pus coming out of the penis or vaginal secretions).

Chamydia & gonorrhoea detection with rapid tests: max 90%

These tests are very useful if you have all the symptoms of gonorrhoea or chlamydia. In other cases they are not very sensitive

  • Our sensitive tests
Our sensitive tests

The nucleic acid amplification test also known as PCR detects more cases than any other test being a technique that looks for bacterial DNA. They are particularly useful in the detection of cases of gonorrhoea or chlamydia in people who are showing no signs of the infection. They are the best tests available. In Open House results take 24 hours. If our schedule allows us to do so, we can do get the result back to you in 90 minutes.

Chlamydia & gonorrhoea detection with sensitive tests: 98 to 99%

These tests are the best for detecting gonorrhoea or chlamydia without symptoms or minimal symptoms

If you want to get the result of the sensitive test in just 90 minutes, a supplement of 40 € applies

Watch video to better understand how we take correct samples for gonorrhoea and chlamydia testing at Open House

If we are going to look for infections in the throat or rectum, we will use sensitive tests only.

Our 20 minute tests don’t work in the throat or rectum, Please read below about the alternative test.

Our sensitive tests

The sensitive tests (PCR) have been recently approved for detection from throat and rectum. They detect DNA of the bacteria and are unbeatable in detection of these two infections. The results take 24 hours normally but if time allows we can do this in just 90 minutes. Although they are much better than standard tests (like cultures, for example), they do not perform as well in the throat (or rectum) as they do in the genitals. However, a more sensitive tools still does not exist.

Chlamydia & gonorrhoea detection with sensitive tests from the throat (or rectum): >90%

If you want to get the result of the sensitive test in just 90 minutes, a supplement of 40 € applies

If you don’t show any of the symptoms of gonorrhoea or chlamydia, then maybe you ought wait before doing the test.

The window period

You can do gonorrhoea test 7 days after the last high risk contact, but in the case of chlamydia you should wait 14 days.
This is not an invention of Open House, rather an international guideline. Open House complies with the most demanding requirements of several leading institutions in the field of sexually transmitted infections: The Spanish Society of Infectious Diseases and Clinical Microbiology, the British Association of Sexual Health and HIV and the European Union via the European Board ITS of IUST / WHO. We are aware that you can get tested at other medical centres but we recommend you to demand the same compliance with these regulations.

More information about these infections and their treatment

  • What are these infections?
  • Symptoms
  • Oral Sex: The main route of transmission
  • Long term consequences
  • I need treatment

Chlamydia and gonorrhoea, are bacterial infections transmitted through vaginal, anal and oral sex or contact with semen, vaginal fluids or anal secretions of infected people. They are very common diseases, affecting both men and women.


Usually asymptomatic, but in some cases from the 3rd week of contact there may be stinging on urinating or abnormal fluid from the vagina, penis or anus.


People who have symptoms, be between day 2 and 10 of infection. It can cause abnormal mucus or pus in the genitals and in women, abdominal pain, fever and irregular menstrual bleeding.

Although many people infected with chlamydia or gonorrhea have no symptoms, if you have any of the following, you should consider testing:

In men, stinging on urination, burning, itching, discharge from the penis;
In women: burning or painful urination, altered discharge, pain during sex.
For both sexes: sore throat, tonsillitis, pus in the throat, rectal secretions, rectal burning or pain, abnormal feeling with stools.

  • According to Open House, 60% of Chlamydia infections in men (in the urethra) have no symptoms and 30% of cases of gonorrhea. Multiple scientific publications support this figure.
  • In the cervix and  throat infections 90% of show no symptoms.
  • You can only be 100% sure of not having Chlamydia or Gonorrhoea by doing tests.

Oral sex is the main route of transmission

The urethra (the tube inside the penis), rectum , throat, and cervix. However, the most common route of chlamydia and gonorrhoea transmission is oral sex (according to our experience in Open House). Chlamydia is the most frequently detected infection in Open House.

Chlamydia is a major cause of infertility

If you are a man and have oral sex or penetration without a condom and you get infected with these bacteria, you can transmit them to another woman without realising it. In women, these infections can be very serious because they cause systemic infections, or can damage the uterus and Fallopian tubes. They are the cause of 20% of female infertility .

Chlamydia and gonorrhoea, vehicle for HIV

The presence of chlamydia and gonorrhoea in the throat, urethra, rectum or cervix can act as a catalyst for HIV transmission. For this reason, at Open House, if you test positive for one of these infections we will always recommend that you do an HIV test as a precaution.

Open House fully complies with national and European guidelines in the treatment of gonorrhoea and chlamydia. We chose the right antibiotic on a case by case basis. Treatment may consist of a single dose or a course of antibiotics.

Outcomes in Open House

At Open House we succesfully treat 99.2% of all gonorrhoea or chlamydia cases in house. Only 0.8% of cases get referred on to other specialists.

If you have had high risk sex for gonorrhoea or chlamydia in the last 3 days, there may be the possibility of administering prophylactic antibiotics. This is not an option for everyone and is decided on a case by case basis. Get in touch with us if you think you might be a candidate.

At Open House, whenever we have used prophylactic antibiotics, 100% of all patient were still negative in tests performed thereafter.

I want to know more about mycoplasma, ureaplasma & trichomonas

Before giving more details about these infections you should know that they are not exactly like gonorrhoea and chlamydia in the sense that if they are silent (without symptoms) they almost never do any damage both in men and women. Many doctors don’t even treat these infections when they are detected by chance, considering them to be part of the bacterial flora. However, it has been shown that the presence of these infections can increase the risk of catching HIV. Therefore, in Open House we always recommend the eradication of these bacteria in women.

Mycoplasma genitalium

Mycoplasma genitalium is such a small and strange bacteria that we can barely detect it in routine tests. There are very few laboratories in Spain that can detect it. It produces EXACTLY the same infections as gonorrhoea and chlamydia (in the cervix, urethra and rectum) but if it decides it is going to be a silent infection, it does not cause any damage.

If we truly suspect this infection (all the symptoms but gonorrhoea and chlamydia negative) we initiate a specific treatment protocol as it is very resistant to antibiotics.

Mycoplasma hominis and ureaplasma urealyticum
  • Are two bacteria that often are present in our genitals without causing problems. However, sometimes they can produce infections similar to gonorrhoea and chlamydia.
  • They are only transmitted in vaginal sex.
  • They do not do any damage if they are silent.
Trichomonas vaginalis
  • Trichomonas vaginalis is a parasitic infection which is silent in about 50% of cases.
  • When it decides to produce symptoms, it is associated with vaginal itching and in men, urethral itching.
  • Chronic trichomonas in men can be a risk factor for developing prostatic cancer.
Mycoplasma, ureaplasma & trichomonas tests

The medical community is not altogether agreed on whether these tests should be done as part of general check-ups or not in people with no symptoms. At Open House, we take this decision on a case by case basis. We can do culture tests for Mycoplasma hominis and Ureaplasma if you have symptoms that make them likely. The need or not to do these tests can always be discussed in the consultation with the doctor who sees you in Open House, this consultation as ever, being free of charge. At Open House we have a trichomonas tests available that detects about 10% more cases than those used in the Spanish Public Health sector.

What is uretritis?

Data on our clinical experience with urethritis or prosatitis in men:

Cases of urethritis or prostatitis managed: 5500

Clinical success in the treatment of urethritis or prostatitis: 98.2%

Other causes of urethritis in men

Urethritis (inflammation of the urethra, the tube inside the penis) is common after sexual contacts. The symptoms of stinging inside, when you pee or on the tip of the penis may indicate urethritis. In the previous section you can read about causes such as gonorrhoea, chlamydia, mycoplasma and ureaplasma as bacterias which may cause urethritis, but there are other culprits.

Non-specific urethritis: when a man clearly has urethritis but the tests are negative, we call this situation non-specific urethritis. It usually responds well to a particular antibiotic. A night out drinking with plenty of sex: After a night of heavy drinking that ended up with good sex, often we see urethritis which is nothing to do with bacteria, rather dehydration, trauma and chemical reactions to condoms. However, if the sex was unprotected, we recommend looking for infections first. Stress is also a cause of urethritis. Urethritis as a symptom of an underlying problem: Sometimes, symptoms of urethritis are not due to a problem of the urethra per se, rather there could be a urine infection, an imminent outbreak of herpes irritating nerves or infection in the prostate.

Information about lymphogranuloma venereum – the superchlamydia

Lymphogranuloma venereum – the superchlamydia

Up until about 10 years ago there had only ever been seen about 100 cases of this serious infection in Spain. In recent years that is has gone up by about 500%. There is not a great deal of practical advice about this disease so Open House will share our thoughts with you here. It is of particular importance to men who have sex with men, who practise fisting or are HIV positive. It is produced by an agressive strain of chlamydia that invades the lymphatic system and can dissolve tissue and glands in the pelvis. Transmission in fistiing occurs from one persons rectum to another. In anal sex, it is transmitted from the penis to the rectum and vice versa. However, just like in other chlamydial infections, there are people who are silent carriers. A urethral infection can produce abscesses in the glands and in the rectum it can cause permanent damage. Key messages: if you have been diagnosed with urethral chlamydia and your glands are very painful, or if you have a rectal chlamydial infection that has relapsed, we should consider the possibility of lymphogranuloma and therefore a specific treatment.
