My question partly, then, is around what is required for informed consent from someone who's in isolation—more specifically, in writing. It was written to me that informed consent is only required in four situations: the consumer is participating in research; the procedure's experimental; consumer's under a general anaesthetic; or the significant risk to adverse effects on the consumer. My question, then, is: which of those criteria does nasal swab testing meet? Because you wrote to me in written questions, saying that that is the only form of written informed consent that occurs with nasal swab testing. So which of those four criteria do nasal swabs meet?
