So todays stats.
No uptick on LFT's from the 31st so only 38k total, so not "later in the day use" (well maybe it was, but not such that it changed the specimen date on the submissions) So yes lower numbers in recent days.
Obvious concern would be if this is related to test availability rather than a genuine fall, although PCR's are more reflective - of course this could also be a test availability issue - particularly if a high proportion of all PCR's were actually from a non-registered LFD which has been suggested!
Admissions fell on NYE, not sure there's too much to read into on that, unique day of course. Total in hospital also grew less on the two days since (only adding 800 over 2 days, whereas had been ~1000 a day growth for the previous 5 days)
Patients in hospital growing at a lot slower rate in London, with admissions dropping but not by as much indicating there probably was a bit of a discharge delay over christmas this year too - it was seen last year.
