Anyone who is coded immunocompromised on their medical record qualifies for fast track PCRs and treatment for anti virals, if you test positive. The anti virals must be given within seven days of a positive test, accoeding to the communication I received.
I had a letter last year with a phone number to call if I have a positive LFT.
I think it's fantastic news that this is available to those of us, who are at the highest risk of death, if we catch Covid.
