We have a working LFT4 Aug 2020 19:35
Thought I'd post again because I'm bored of the wyndrum thread.
We were informed via RNS this:
"These data show that the test strips detect the spike protein in model samples at concentrations within the clinical range found in saliva of patients with COVID-19. Work continues now to refine the test strip design, optimise its performance and get the best detection limit possible in order to generate the highest sensitivity in the final rapid test product."
That was 6 weeks ago.
looking at Sona's news flow (who IMO are the best comparison we have) on 12th may they released very similar news. 7 weeks later they released their validation results ....
So I would surmise that we are not far off, but we have the added nutralising requirement to add to the device too.
