How does an STI test work?

How does an STI test work? We often get this question how an STI test works. Below you can read the steps we take to test and treat you for STIs.

How does an STI test at OneDayClinic work?

How does an STI test go? After you have made the appointment there will be a confidential interview with the certified STI doctor. During this conversation a number of questions will be asked to assess your STI risk. Based on these risks, the doctor will give advice on which tests should be taken in your situation. Together with you, a decision will be made about which tests you eventually want to take.

What STIs can you have?

You will be asked a number of questions: whether you have sex with men, women or with both sexes and whether there has been oral, anal or vaginal sex. This is asked because the STIs chlamydia and gonorrhoea can occur at different locations in your body. Infections with these STIs, which are caused by bacteria, remain fairly localised and don't just spread through your body or blood. You may have contracted chlamydia in your anus and not in your throat while having had anal and oral sex. How an STI test works depends on what symptoms you have and what you need to be tested for.

Do you have to take off your clothes for an STI test at OneDayClinic?

Physical examination is often not necessary. HIV, syphilis and hepatitis B and C are excluded by means of a blood test. Chlamydia and Gonorrhoea are tested in the man's urine and in the woman's urine via a 'self-swab' (i.e. with a cotton swab). If oral and anal sex has taken place, it is excluded via an anal swab or a throat swab. You can do this yourself, but you can also leave this to the doctor.

  • Urinalysis

The examination for chlamydia and gonorrhoea in men can be done using a urine sample. When you are infected, bacteria can be found in the urine in particular. In women, a self-swab is more reliable than a urine test.

  • Blood test

Syphilis, hepatitis B, hepatitis C and HIV can be detected by means of a blood test.

  • Selfswab smear

A smear removes moisture from the vagina. This determines the presence of chlamydia and gonorrhoea. This doesn't hurt. Because chlamydia and gonorrhoea can be found in different locations (vaginal/channel/throat), additional swabs may be required. The doctor will determine in the initial interview whether this is necessary.

Do you have any complaints that indicate an STI? Then don't wait and make an appointment for an STI examination.

What do you have to watch out for before an STI test?

When making an appointment, it is important to take into account the window phase. The window phase is the period between the sexual contact (possible moment of infection) and being able to detect the infection with the test. For testing for chlamydia and gonorrhoea we keep two weeks after the sexual contact (on indication this is sometimes possible earlier). For HIV, syphilis, hepatitis B and C we stay for three months.

The man shouldn't have been to the bathroom for at least three hours or taken morning urine.

When do I get the results of my STI test?

The treatment of an STI at OneDayClinic

Chlamydia, gonorrhoea and syphilis can be treated with antibiotics. For this treatment you can also contact the OneDayClinic. However, HIV is more difficult to treat. There are medicines to suppress these STIs and their symptoms, but not to remove the viruses from the body. OneDayClinic will guide you for further treatment and refer you to a specialist in the hospital.

Warn your partner

If you have an STD, it is important that you warn your partner(s). Warn not only your current partner, but also your ex-partners. They can also have the STDs without having any complaints. They can then pass these on to their partners unnoticed. By warning your partners, you prevent the STDs from spreading further or that they are faced with serious consequences because they have not been treated.
