No idea, just know it as the day 2 test (can be done earlier) they send it by post, and you send it back:Hi guys. We’re travelling Friday - Sunday and have a dam health PCR test booked Thursday which from what I can gather should cover us for the return flight. Does anyone know which test is required for the 2 day allowance? Does this need to be another PCR or can it be antigen? Thanks in advance.
