How do I submit my Day 8 PCR test sample?

If you’re required to take a day 8 test after you’ve returned home, you can return your test(s) to our lab directly via the enclosed prepaid address label. We use Royal Mail Tracked 24 and other couriers for the quickest service available, usually next working day delivery. 

If you’re using the Royal Mail service, just drop it off at a priority post box – you're allowed to leave your isolation address to do this.

If you’re using a different courier, please follow the instructions provided to either arrange collection or drop off the parcel. 

You’ll get an email from Chronomics as soon as we’ve received your test(s), and another email 24-36 hours later to let you know that your result is available via your secure Chronomics online dashboard, which you can log in to using the same details as when you registered. 

Your test needs to be registered before returning it to us. Your returns package should only include your test. Do not send your sample back with any notes with your personal information on, or notes explaining that you can’t register your test. This is to ensure we keep your information secure and comply with government regulations for data protection.

If you experience issues when registering your test, you can get help by using our interactive knowledge base that can guide you to tailored advice. You can find this in the bottom right hand corner of our website and app. Just click on the blue question mark to launch
