No matter what sexual orientation or identity - you are welcome!

If you suspect having been exposed to a risk of infection, you can be tested at the checkpoint. We offer a detailed and non-judgemental consultation before getting tested which promotes a more conscious health behavior. The consultation and testing is confidential. Due to Covid-19 security measures you have to make an appointment for the checkpoint though.

Next date:

Appointments can be made via phone (see number and calling times above). Please note that appointments can't be made any earlier than two weeks before the Checkpoint date.
