How and when do you test for STIs? A complete guide

Did you know... STD - STI

If you have had unprotected sexual contact, it is wise to get tested for STIs. The timing and frequency of testing depend on your lifestyle, sexual activities and preferences. For the most common STIs such as chlamydia and gonorrhoea, there is a waiting period of about two weeks before they can be reliably detected, while for HIV, syphilis and hepatitis B this is between eight and 12 weeks.

When to take immediate action?

  • You should take an STI test immediately if any of the following situations apply to you:
  • You have been alerted by a partner that they have an STI.
  • You are experiencing symptoms that may indicate an STI, such as unusual discharge or pain during urination.
  • You have been at risk of HIV infection, especially if you have symptoms similar to a severe flu.

Regular testing: for whom and how often?

It is recommended that you get tested at least twice a year if you:

  • Have many different sexual partners.
  • Participates in the swingers' community.
  • Are at high risk of HIV and other STIs, such as men who have sex with men and sex workers.

Note: Do not delay testing if you have symptoms or have been warned of an STI, regardless of the time of year.

Specific recommendations for incidental unsafe contact

After occasional unsafe sexual contact:

  • Get tested for chlamydia and gonorrhoea after 14 days.
  • Get tested for HIV, syphilis and hepatitis B 8-12 weeks after contact.

This is essential after unsafe sexual experiences, including cheating or unsafe encounters abroad.

Continuous protection: The importance of precautions

Even though it takes a while before STIs can be reliably detected, you can still transmit them to others. Use a condom in the period until you can reliably test to prevent further spread.

Healthy together: Test as a couple

If you are starting a new relationship and are considering sex without a condom, get both of you tested. Ideally, wait three months from the start of the relationship before having sex without a condom to test reliably for all STIs.
