Very efficient and quick response. As one of the Trusted Test Centres, I used Confirm Testing when I was travelling out of the UK and on my return. My in-clinic PCR test experience was great with results in less than 24 hours. On my return, my days 2 and 8 test kits were delivered before my arrival in the country. Test instructions were simple and easy to follow. Postage was simple with tracking so you know when your sample is delivered. Results in less than 24 hours once sample is received. I highly recommend Confirm Testing. They are by far the most affordable and the best.
