The initial evaluation of Avacta's lateral flow rapid antigen test with clinical samples has been carried out at two sites, one in EU and one in the UK using patient samples with viral loads confirmed by PCR. 30 positive samples were tested with Ct values of 26 and below, with half of those in the range 22-26, and the lateral flow test identified 29/30 of these correctly as positive. This indicates a clinical sensitivity of 96.7% for samples with a Ct value below 26. Importantly, out of a total of 26 negative samples tested with the lateral flow device, the test correctly identified all 26 as negative, giving a clinical specificity of 100%. High specificity is critical for a lateral flow test for mass screening so that large numbers of false positives are not generated which would create a major burden on follow-on testing resources, and result in a significant socio-economic cost of unnecessarily isolating people.
