We apply this test every day to every visitor, patient, and staff member without fail. It is very easy to use, produces positive results sometimes within 2-3 minutes and is always extremely reliable and accurate. We have a great confidence in this excellent test and it is relatively inexpensive for what it does.

Our hospital has purchased thousands of Excalibur tests to test staff and visitors across the site. We are using them as the first line of defence as per government guidelines. They have already proved their worth in picking out a number of asymptomatic positive Covid visitors. The tests are very reliable, easy to use and robust. I would highly recommend them in any setting where safety is a concern.

We have bought thousands of Excalibur Rapid Antigen tests and are extremely impressed. We found individuals with no symptoms who showed up as highly infectious. These are excellent and invaluable screening tools developed by Excalibur – use them and stay safe.

We have evaluated the Excalibur test in our laboratories and found the test to have high analytical sensitivity and specificity. The importance of mass screening for COVID-19 cannot be underestimated, as we saw in the trial in Liverpool which resulted in Liverpool being moved down to Tier 2 in November.
