General Information
How are STIs transmitted?

Most STIs are transmitted through unprotected vaginal, anal or oral sex.

They can also be transmitted through direct skin-to-skin contact, by sharing sex toys or devices used to take drugs or through maternal-foetal transmission during pregnancy/birth.

When do I need to get an STI test?

It is recommended that people who have unprotected sex with several sexual partners get periodic STI testing. Many STIs are asymptomatic, and if they are not treated in time, they may lead to serious health problems, which is why it is so important to get tested regularly.

In addition, it is recommended that you get tested each time you begin a new relationship with a new sexual partner or if you want to stop using protection with a usual sexual partner.

How much time should I wait before taking an STI test?

To detect an STI, it is imperative that a certain amount of time pass between the at-risk contact and the time the test is taken so that the result will be reliable. This time is called the “window period.”

If symptoms appear during the window period, you should have a medical consultation to evaluate if your symptoms are consistent with any STI, and if so, to evaluate the possibility of performing tests before the window period has ended.

What are the window periods for STIs?
  • Gonorrhoea, chlamydia and Mycoplasma genitalium: 2 weeks.
  • Syphilis: 3 weeks.
  • Hepatitis B: 4 weeks.
  • Hepatitis C:
    • PCR viral load: 14 days.
    • Antibodies: 3 months.
  • HIV:
    • PCR: 10 days.
    • 4th generation - p24 Antigen and HIV Antibodies: 4 weeks.
    • Antibodies: 3 months.

Remember: if you have symptoms, you do not need to wait for the window period to be over; instead, you should see a specialist physician to evaluate these symptoms.

Which STI tests are relevant for oral sex?

In our experience, this is the most common way in which some STIs are contracted, as it is typically performed without protection. After having unprotected oral sex, whether you have given or received it, it is recommended that you get tested for gonorrhoea, chlamydia and syphilis.

If you are unsure about the risk of the act performed, we recommend going to a prior consultation with our sexual health specialists.

Which STI tests are relevant for vaginal sex?

Having unprotected vaginal sex puts an individual at risk for gonorrhoea, chlamydia, Mycoplasma genitalium, syphilis, hepatitis B and HIV.

Furthermore, it is possible to be infected with other STIs such as Mycoplasma hominis, Ureaplasma, Candidiasis and Trichomoniasis by having vaginal sex. However, many of these infections are caused by bacteria that form part of the vaginal flora; therefore, they only need to be detected and treated if you are having any symptoms.

If you are unsure about the risk of the act performed, we recommend going to a prior consultation with our sexual health specialists.

Which STI tests are relevant for anal sex?

Anal sex significantly increases the risk of contracting an STI, as it is the most likely way of acquiring these infections. Therefore, it is recommended that you get a complete check-up for gonorrhoea, chlamydia, Mycoplasma genitalium, syphilis, hepatitis B and HIV.

If you are unsure about the risk of the act performed, we recommend going to a prior consultation with our sexual health specialists.

I had sex with someone outside of my relationship, can I transmit an STI to my partner?

If it was protected sex, there is no risk of STI transmission. If the sex was unprotected, avoid having sex with your partner or use protection until you have gotten tested.

It is important to get tested for relevant STIs depending on the type of sex performed after the window period for the tests unless you have symptoms consistent with infection.

How can an STI affect pregnancy?

When you plan to have a baby, it is important that both parents get a full health check-up, including sexual health.

Some STIs can cause pregnancy complications or be transmitted to the baby, so it is important to get tested if you have not done so previously.

I found out that one of my sexual partners has an STI. What should I do?

At Open House, we offer you two options in this situation:

  • Come in with the report that provides your partner’s positive result. In this case, the doctor at the consultation will make the decision to perform the test or directly administer treatment.
  • If you do not know which STI you have been exposed to, get the relevant tests based on the sexual activities you have had with that partner.
I had a condom break. Do I need to get tested for STIs?

Yes. Even though the risk is higher if the sex is unprotected from the start, prolonged and includes ejaculation, at the moment sex becomes unprotected, there is a risk, so it is important to get tested.

Is it necessary to get tested for STIs if the other person did not ejaculate inside me?

STIs are not only transmitted through ejaculation. Therefore, if you have had unprotected sex, you should get an STI test based on those sexual activities.

I had sex with a sex worker. What test should I get?

Regardless of who you have sex with, anytime unprotected sex is performed, you should get an STI test to check if you have been infected.

While it is true that sex workers are more exposed to contracting sexually transmitted infections, it is also true that, generally, they get STI checks more frequently than the general population.

Can I get tested if I am a minor?

You can get STI tests independently if you are aged 16 or older; if you are below this age, you must come in with a legal guardian who will authorise us to see you at a medical consultation and/or test you.

Can I get tested if I am taking medication?

It depends on the type of medication you are taking and the test you want to get; you’ll either have to wait 15 days from the last time you took it, or you can get tested right away.

Send us an email at [email protected] with this information and we will inform you if you can get tested or if you should wait.

Can I get tested while I am on my period?

If you are on your period and you have to collect a vaginal sample, it is better to wait until your period is over, as the reliability of the test could be affected.

Do you work with private health insurers?

No, but you can request a bill and submit it, along with the medical report, to your insurer, as there are some who do reimburse payments made to our clinics. Check with them beforehand, and we can help you with any documentation they request from you.
