Okay. So, that's not at all in my portfolio; that's obviously for my colleague Vaughan Gething, and I can't pretend in any way to be an expert in the different testing regimes or the percentages or anything else. My understanding is that those tests aren't particularly useful to individuals; they're more useful to the Government to understand where the virus has been and what the spread might have been. They're quite invasive tests; they require taking a vial of blood from people and so on, so they're not a finger prick or a swab in your cheek, and it doesn't tell the individual very much because, as yet, as I understand it, we don't know, if you've had the disease, whether you've necessarily got immunity or how long it lasts for and so on. 

I understand that there's a document going out to school staff about the test, and explaining what it does and why people should or shouldn't have it and so on, and I don't see any reason why we can't share that with Assembly Members—sorry, with Members of the Senedd. And so I'll make sure that that happens, Delyth, because I cannot at all pretend to be an expert in that.
