I agree with you the Mologic test is better than Innova, it uses AN sampling as opposed to being a pharyngeal test dressed up as an AN test, I don't dispute what you are saying whatsoever in that regard.
However... with regards to comparable performance; here's AffiDX
"The study tested 98 positive samples (31 with Ct<26; 65 with Ct 26-30 and 2 with Ct 30-31). Avacta's rapid antigen test identified 96/98 of these correctly as positive with a 20 minutes read time resulting in a clinical sensitivity of 98.0%"
I've followed the Twitter link you sent me and looked in the comments, where there is a screenshot of the FIND report.
"Sensitivity Ct <25.... 96.4%"
So therefore Avacta are achieving a higher sensitivity which is also in mostly **samples where the virus is harder to detect.** It's doing better, in worse samples!
(Remember, the lower the PCR CT value, the easier it will be the for Lateral Flow to correctly identity the sample as positive.)
The Mologic tweet may be true in that Avacta don't have a CE mark yet (which is of course a formality and will happen), or is technically best in class because the Avacta test is S protein not N protein.
The fact is, the numbers are there for all to read and the AffiDX test is showing better performance.
So my point is this, IMO the UK Gov will either go for performance or for price. We don't know the prices of all three tests, but we can probably assume Innova will be cheapest, so that would probably be appealing from that angle.
I would guess that Mologic and AffiDX will be in the same price ballpark, which if that's the case, why would the UK Gov chooser the lesser performing test - it wouldn't make sense. Furthermore, why would Mologic help develop the test and then GAD be handing over manufacturing capacity to Avacta to make a test worse than their own - again... this wouldn't make any sense at all. What would be the benefit of doing that?! Handing over capacity to make a test which won't sell as well... crazy and irrational to believe!?
So my point is - unless another private company comes from the left field and blindsides us all... it's almost certainly going to be Innova or AffiDX. Price, or performance.
I can't see ODX manufacturing the Innova tests. Innova's are already monstrous and expanding further... ODX would be a drop in the ocean, so why bother? They probably wouldn't.
AffiDX needs to be the 'Sovereign Test' and ODX need to be making it.
