If you're taking your test soon, please don't post your sample back to us if the outside temperature where you are goes below 0 degrees.
This is because the freezing temperatures could affect samples whilst on the way to the lab — and we might not be able to analyse them.
As soon as the temperature is above 0 degrees in your area — please feel free to send your sample back to us.
If you have to post your sample during low temperatures — try and post it closer to the collection time so that it's not sitting in a freezing postbox for a long time.

Please drop us a message to hello@thriva.co if you have any further questions at all.
