Needed a Rapid Antigen Test for a family of 4, to go on a cruise this Summer. Needed it 72 hours before embarkation. Roshni were brilliant and friendly on the phone; explaining everything they do, how it works - and that they have plenty of cruise customers for these tests.
Found Rotherham Football premises quite easily. There is a large open reception area: which is essentially to serve people playing "Indoor Football". BUT - they perform these tests as "Administrators" for Roshni Clinic.
It's pretty much the same as you get from these "over the web" services: where someone actually watches you take the self-test, but on their premises, in-person.
They take the Barcode from your test, the sample results (which you place in a plastic bag for them) - and take digital images. These are then passed to a central laboratory; where a Clinician casts a more 'professional eye' over the test result - and then issues your certificate.
We could obviously see that our tests were NEGATIVE, before we left the premises. We received an email almost immediately that the test was registered with the laboratory. We received the confirmation of negative test (with accompanying PDF certificate) in about 1-hour.
Travelling with Princess cruises, we could upload the certificate to their booking/cruise application - and I have since had someone check it (over the phone) and confirm that it meets their requirements.
So: now feel confident that I can fly to Rome, meet the ship - and actually board, relatively stress free.
I would thoroughly recommend this service.
