Having recently been obliged to take a lateral flow test for Covid in order to fly from the UK, I idly wondered:
What is the control antigen for Covid lateral flow tests?
as (fortunately) that was the only band I saw.
Easy — just Google? You jest! “Other people asked”, “All you need to know” and even the scientific papers linked just talk about the target antigen.
This sort of thing really gets up my nose!
Could someone please tell me what it is up my nose?
