Question For The Prof Or Other Sciencey Type
We are told that LFT's should only be used before there are symptoms. I have been trying to find out what the science is behind this (not that i disbelieve it or am against testing) Someone who understands a bit has told me that the reason is that too high a viral load on the test denatures the enzyme used and therefore the test doesn't work. I have hunted and hunted but can't find any research or evidence on this and wondered if anyone with proper knowledge can help?
Thank you.
Yes I know I have put this in the "wrong" category but covid testing IS news and I thought I'd get more traffic here

NJ, no matter which way you choose to look at it, you asked a question that was moving into political realms. Yes, perhaps there was insufficient detail for you in the remarks made by theprof but did you really expect him to expand upon the statement.
You speak about theprof discussing only one aspect of this sorry state of affairs. Who do you think has the ability to discuss all aspects? He has answered in his area of expertise just like Valance and Whitty will not discuss the politics from their lecterns. You need to look elsewhere for the political answers you require

//TheProf has made clear that he will not discuss politics and political decisions here on AB...//
Then he should not have made a comment on what would be a purely political decision. He cannot have it both ways. There's nothing at all puerile in asking someone to elaborate on a comment they have made.

No I didn't. I asked for a comment on a political statement made by the Prof (i.e. "I'm with the great and the good on that"). I wasn't looking for political answers. I was asking simply for an expansion on something The Prof had stated and if he wasn't prepared to expand on it due to his own restrictions it might have been better if he had not said it.
Anyway, lesson learned. We're all free to pick and choose which posts we respond to.

Although we have no idea who The Prof is, I suspect any scientific colleagues who stumble across AB might make an educated guess - which would make it absolutely imperative that he/she is seen to be posting solely on 'the science' and avoiding evincing any political opinions whatsoever. He/She must be the sole judge of where the boundaries lie.
I value The Prof's posts and very much hope that they continue to cast light into some interesting scientific corners.

It shouldn't be too difficult. From this thread alone we know that his laboratory is in the West of England and that there are 172 in his team. That must have narrowed it down a bit for any of his colleagues who might "stumble" across AB.

I don't have the answer, I'd have to look it up in presumably the same way you've tried (internet search). But hopefully this is helpful to someone who *does* know.

never another wiser word
it is not often that you have a molecular biologist telling us what is going on in the Virus of DEAAAAAATTTTTHHHH!
n I dont recollect NJ saying he had poked a nose into a virus lab
two things - Frackhead Fergus on Beeb as I write !
and first death from Omicron - deaths start in the third week and here we are
Frackhead Ferge says it doesnt tell us very much - Deaths have started Fergie! Huuuuullooooooo! ( sing songy voice needed)

q no 1 - no there is no cross reaction in the LFT with common cold
( too cx for AB? - then the answer to the first question is 'no' )
q.2 - not sure - - question about control line - specifially what is the nature of the positive control....
https:/
awful lot here - huge amount - psst wanna know about Lat flow immunoassay? - then look at that site. Dirty pictures too, viruses and things. over to you Pixo!

It wasn't a political statement NJ. How did you want him to respond to your comment? Did you want him to plaster the science over AB so that you could be convinced? It was a summary of his feelings based upon what he sees and knows and he should not need to justify it.
Turning to the matter of restrictions, none of us know the restrictions that are in place on theprof. Frustration and anger over this seeming lack of candidness by scientists and government is no justification to harangue those that are trying their best to put an end to this pandemic.

oh, did Prof answer?
it is here
https:/
and the label says - alpha-IgG
which in the er C19 at porton we called antiglobulin
it reacts against ( shows pos) any antibody ( antibody against.... antibodies) (*) and shows that the sample is in fact snot
(*) the first fella to do this I think was Coombs, 1955 inventor of the Coombs test which revolutionised rhesus disease in liddle liddle babies. The evil evil antibodies that was killing the baby would show up against a coombs reagent and give the diagnosis. Coombs went to my old college as it happens.

two links for Corbo and Pixo
if anything appears er unclear then please repost hur hur hur
( God an ABer cant pling on an URL, seen it all)
oh and can we stop pot shotting at The Prof - he had said he is a spatial molecular chemist and that seems clear enough to me
( = lab - wallah to you proles) ( posh or chief lab rat)
and has declined to answr political questions
[like: foo prof, you voted labour in the last election or wha'?)

Corby, there's no quick way that I'm aware of to find a specific answer. The way I do it is to hover over the "report" button, so that I can see the answer code, and then insert it in place of the nnnnn's in the link below:

But this relies of course on having found the answer you were looking for already. AB's search function is helpful if you know some of the text in the answer, but even then it's not necessarily brilliant.
