Needed some clarification When I saw todays announcement I initally was not that impressed on the 99.9 % and 99.5 % accuracy. Previously I was convinved that 100% and 99.9 % was going to be almost necessary for a valid test. Clarification gave me a better understanding of what was happening.
First thing is that PMN's test is based on SPR and not ELISA . It appears as though we are the only one out there doing SPR development. I now know that SPR are is more difficult but in the end it is more accurate, more stable and will be the best way to know if the antibodies present will protect the host against the virus.
"But the key step in development of a ‘best in class’ test is to create an assay that not only detects the presence of antibodies specific for the SARS CoV-2 virus but importantly, also allows to determine whether or not the detected antibodies have neutralizing activity, potentially conferring protection from COVID-19
The vaccines are developing at a unprecidented pace and PMN's test will be very important when it comes to getting a fast evaluation, capable of high volumme testing to see if the vaccine is working. There is stil alot of work to do but I feel that its already well underway. I am of the opinion that this newsrelease is not real time and that we could be looking at a picture that has happened awhile back and the next stages of development are well underway. We will hear more and possibly get some opinions from otrher experts in the field of test development. Like usual, unless you are scientist this reveal will not mean as much ... but as I say that the market seems to have reacted to what was stated. It was also clear to me that there will be more info coming out in the near future and it appears to deal with covid...
