Sorry, I am not an expert so I don't know. However, in the UK they can use lateral flow tests.
I believe that some pregnancy tests are also lateral flow tests and these days many would say that it is wise to check whether your husband is pregnant or not!
So what test are they using.? My husband had surgery yesterday and he said they stuck a swab up his nose for a rapid covid test.
