Each test kit contains a "Retourbox", which is found underneath the cardboard interior in our large test kits. With small test kits, the Retourbox can be pulled out of the product sleeve (it may be a little tight!):
The Retourbox has the correct address of the lab printed on it and postage is already paid. Just put the sealbag with your sample in it, close the Retourbox with the "Seal to close" sticker and take your Retourbox to a post office (preferred) or the nearest yellow mailbox.
⚠️ Send your Retourbox WITHOUT any cover (e.g. product sleeve, an envelope or a box) to the lab. Otherwise Swiss Post will deliver it incorrectly - or not at all.
Different lab per test kit
If you have multiple test kits, e.g. a Basics STD test and a Premium STD test, make sure to send in each sample in its "own" Retourbox, as they are analyzed in different locations of our partner lab MEDISYN SA. Refer to the overview in case of doubt.
