Please can anyone help me find the correct information regarding asymptomatic isolation before the 11 January rule change.
Before the rule change, I always believed that if you got a positive lateral flow and were asymptomatic, your day 0 didn't start until the day you took the PCR test. But I'm struggling to confirm this online as all the nhs and gov websites now only tell me about the new rules which say a follow up PCR is not required for asymptomatic cases and day 0 is the day you took a LFT.
I require this information to stop someone from ending their isolation early as they believe their day 0 is the day they took the LFT and not 2 days later when they took a PCR, which all occurred before Tuesday 11th. Not going to go into why they waited 2 days for PCR, I didn't agree with them and I've argued enough with this person over it. I don't know what test and trace will have told them, even if I ask they will probably twist it so they are right.
