My mum lives alone, is partially sighted and has to take a PCR test. She is unable to do it herself or get to a test centre. Should I call 119 and ask if they have people who can go into the community to do this? Our whole family is having to self isolate as someone tested positive after our Christmas get together, so none of us can help her. We all tested before hand but obviously LFTs are not 100% foolproof.
