I want to do a hepatitis test



I want to learn more about hepatitis (A, B & C) and its vaccine



I would like to do a complete sexual health check-up



What are the symptoms of sexually transmitted infections?



I would like to know the risks of hepatitis A, B & C in oral, vaginal or anal sex



I’m in a relationship and have had sex with someone else – I’m very frightened!


I want to test for the hepatitis viruses:

Hepatitis A:

Cases of hepatitis A without symptoms do not exist, therefore we only do this test in patients with a relevant clinical picture (for example, with jaundice).

Hepatitis B:

Cases of hepatitis B without symptoms or with mild symptoms are common which is why we condlude this test when there has been unprotected vaginal or anal sex. Our tests can detect the same number of cases as a laboratory test, but before proceeding, please read our referee’s recommendations.

Open House uses the most astringent of all clinical recommendations and scientific publications in making this recommendation. The test that we do detects 99,8% of infections once a 4 week period has gone by since the last high risk contact.

The test that we do detects 99,8% of infections once a 4 week period has gone by since the last high risk contact. However, if you have symptoms conspicuous of hepatitis B, then there is no need to wait out this window period.

As always, Open House recommends that you ask to be shown studies supporting claims if you decide to do this test in another clinic and they say it can be done prior to the 4 week watershed.

Hepatitis C:

Hepatitis C is much more common that HIV, we don’t generally consider the sexual route as its main way of being transmitted, because it needs blood to blood contact. You can read more about the way it is transmitted below.

We have two hepatitis C tests, one that detects more recent infections than the other. below you can read what our referee has to say about them.


Do you want to know if you’ve high risk sex for hepatitis B?


How can I catch hepatitis C sexually?


Find out about the window period


There are two kinds of tests:  a standard one and another that can detect very early infections

If three months have gone by since the possible exposure, we can do a normal antibody test and get the results to you in just 20 minutes.

But if you don’t want to wait, we can always do a test called NAAT (or PCR) which looks for the genetic material of the virus which is detectable just 14 days after exposure.  The results take 24 hours usually but we can get them back to you in 2 hours.

Antibody test: price 65€

PCR test results in 24 hours:  price 150€

PCR test results in just 2 hours:  price 190€

There is more information in our scientific bibliography about this subject.


Call us for an appointment and we make the decision on which is the appropriate test together.

Please trust our clinical judgement. In Open House is successful in the treatment of 97% of cases of warts.

Caution! is important to look at our schedules before calling us and make an appointment.


Hepatitis (A, B & C): Information and vaccines


  • Hepatitis A
  • Hepatitis B
  • Hepatitis C
Hepatitis A

Hepatitis A hepatitis A is the viral hepatitis that we least see in Open House. We only see it in men who have sex with other men.

Many people have been vaccinated against hepatitis A for travel reasons (Africa, India etc., ) because normally it is passed on in food or infected water. But because it is an intestinal infection, it can be passed on to the mouth in sex.

Hepatitis A cannot go on to produce a chronic disease like hepatitis B & C, but the infection is full-blown with jaundice and with a very long convalescent period afterwards.

  • Candidates: men who have sex with men who are not in a closed relationship
  • It works and it’s safe: Really well tolerated. You will need two doses to give you 10 years protection
  • Where to do it: It can be administered free of charge with your family doctor (in Spain it also requires a medical inspector’s sign-off) or we can write a prescription and do the vaccines ourselves if you prefer anonymity.
Hepatitis B

The virus that produces hepatitis B is probably 100 times more infectious than HIV

  • We see more cases of hepatitis B from licking the anus than we do HIV.
  • The hepatitis B virus is extremely resistant outside the body, in fact it can exist for several days in an active state in this environment.
  • Hepatitis B has even been shown to de transmitted by sex workers who are themselves vaccinated due to the virus being present in their bodies from a previous client.
  • Full blown hepatitis with jaundice is not common but rather it can develope into a chronic infection.
  • An infected person can become a carrier without knowing it. This happens in about 10% of all cases.
  • Candidates: (in Spain) men and women currently not in a closed relationship and born before 1983. Spanish people born after that date have been vaccinated at high school. Those vaccinated prior to to the year 2000 should receive a booster.
  • It works and it’s safe: Extremely well tolerated. Three doses are required to afford protection that last 10 years. After the third dose and after 10 years a blood test should be done to check that protective antibodies have been produced.
  • Where to do it: It can be administered free of charge with your family doctor or we can write a prescription and do the vaccines ourselves if you prefer anonymity.
Hepatitis C

Less than 3% have been as a result of sexual contact, since blood to blood transmission is required (see below).

Only 20% of infections resolve spontaneously. The others can persist for many years without producing symptoms. Thereafter there can be a rapid progression to fibrosis of the liver en just a few years and even a risk of developing liver cancer.

Just like with hepatitis B, the overwhelming majority of cases of hepatitis C show no symptoms. In the late stage, generalised symptoms may be more common, for example tiredness, lack of energy or loss of appetite etc.

Only 3% of hepatitis C cases are transmitted in sex, the vast majority occurring in blood to blood contact (sharing needles, in infected blood transfusions in foreign countries). Sometimes there may be a risk in anal sex, but the four circumstances in which the risk is exaggerated are fisting in groups, sharing dildos or toys, having sex during the period and sharing cocaine doser.

Despite advances seen with hepatitis B and HIV there is still no vaccine against hepatitis C.

In recent times, new treatment options have been developed for hepatitis C, but the majority of patients on treatment are unable to work because of side effects.

This disease is one that most danger poses for your sexual and general health. Using a condom in penetration, clean and fresh gloves in fisiting, and washing any shared sex toys before reusing them can reduce the risk of catching hepatitis C.
