How it works

Royal Mail

Order before 1:30pm for same day dispatch* using Royal Mail Tracked 24 Delivery. Your kit includes a pre-paid Tracked 24 return envelope and can be posted in a priority post box.

*Fit to Fly and Diagnostic tests are dispatched the same day when booked before 1:30pm, Monday to Friday. Bookings after 1:30pm on Friday will be dispatched on Monday. No deliveries on Sundays or Bank Holidays. Day 2, 5 and Day 8 tests will be dispatched for arrival on their respective days.

Priority Courier Service

Order before 6pm for next-day delivery by our courier partner, who will send an email to confirm delivery/pick-up time.  Upon arrival, the courier will hand over your kit and wait for you to take your sample and then return it to the lab on the same day for an expedited turnaround.

If you are not able to take the test whilst the courier waits, you can send the test back at your own convenience via Royal Mail to the address below:

Oncologica UK,

Suite 2 Newham Building

Chesterford Research Park

CB10 1XL

Place your completed sample in the enclosed biohazard bag and then place inside suitable packaging. We recommend that you use Tracked 24 or Special Delivery services and take note of the tracking number.

Note - if we deliver your test and you are unable to take it at that time, we cannot arrange another courier to collect your sample. This delivery method is not currently available for Day 2 and Day 8 testing. If you've booked a Test to Release kit, your kit will arrive on Day 5, in line with government guidelines.


We deliver our rapid antigen/LFD tests with DPD. Order before 1:30pm for next-day delivery*. Once dispatched, you'll receive an email notifying you of your delivery time slot. You do not need to return these tests to a lab.

*Bookings after 1:30pm on Friday will be dispatched on Monday.
