Avoid this clinic for your 72 hour test to travel covid test. They purport to offer a "guaranteed" result time, but did not in my case. In fact I still have not had my result some 30 days after taking the test.... I had to source and get a "same day" test with another provider at an additional £199 cost in order to be able to fly the next day to reunite with my son in Canada who I hadn't seen for 2 years, so you can imagine the added stress and anxiety Vivo has caused. I have finally had the refund of the £125 test cost (although only after a number of (ignored) emails) as a result of a phone call and a helpful call handler - so credit where credit is due in her respect. Otherwise a very disappointing and unreliable service in a context where a tinely result really matters.
