VISITECT® COVID-19 Antigen test results1 May 2021 19:05
Hi All,
I've seen a lot of people discussing the recent results of the VISITECT test, and subsequent ODX RNS, which states: "The VISITECT® COVID-19 Antigen test has demonstrated excellent performance characteristics through independent multi-centre validation studies. The test has sensitivity of 98.4% on samples with a cycle threshold (Ct) of < 20 (85% overall sensitivity on samples with Ct values ranging from 9.8 to 43) and specificity of 97.8%."
While they fail to provide a breakdown of the results in that RNS, it's worth noting the performance data for the test has been available for some time: https://mologic.co.uk/wp-content/uploads/2021/03/COVID-19-rapid-antigen-test-February-16-2021-v1.pdf
In particular, its worth noting that the VISITECT test has a sensitivity of 90.2% at CT <25, which is just barely in the governments required 90% range (AffiDX has a sensitivity of 100% at CT <27 FYI).
The biggest worry for the Mologic VISITECT test, is the low ease of use score: 57/100, this is likely due to the tests Nasopharyngeal collection method (brain tickler) which is more complicated versus our simpler Anterior Nasal collection method.
It is good to see their test getting independently verified and I'm sure we will see the same from our own soon.
