Yes, absolutely.
While everyone is running around with their hair on fire yelling about "test accuracy" and "gold standard", they forgot to note two very important, I'd say "critical" facts about what we want to know in this situation.
We want to know if a person is 1) shedding high quantities, 2) right now, as the person walks in.
Let's see how a PCR test holds-up. One fact is that people who get over the disease show PCR positive for a long time (a week or two) after they are no longer shedding 'live' virus. So that test would be a false positive for our purposes. Then there's the time lag. 3 days is common, and often it's longer. If you look at the acquisition Ct curve, you see it goes from nothing to it's 'max' value in 2 days. That means a negative three days ago says nothing about viral shedding today.
The lateral flow assay technology is close to 100% accurate at finding people who are shedding large amounts of virus, and it tells you in 15 minutes. To me, in the eyes of public health, it's a crime that this technology has been hampered.
