Yes, if it remains "prescription only" because it means the sick person doesn't have to go out to a public place for testing, possibly infecting others and allows the sick person to remain at home, resting as they should.

When I was sick with what I suspect was Covid-19, there was no testing available, this was in early January. I did go to the urgent care center and was kept in an exam room for 4 hours, before being sent to the hospital for blood tests to rule out other illnesses. Feverish and feeling ill with no food or water, basically for 6 hours, and having to drive myself, nearly jumping a curb by swinging to wide on a turn due to super slow reflexes while having a high fever, put others in danger in addition to myself. An in-home test would have avoided all this.

BTW - the CDC was called into the urgent care center and ordered a nasal swab test from me, but that test was "canceled" because at the time, I didn't meet all the requirements for testing. Super disappointed that I will never know if the mystery illness I had was covid-19 or not, until anti-body testing is available, which I hope is soon. It's important to me to have that information to know what long lasting effects might be going on with me - besides possible immunity which would be wonderful - I worry how long I might be contagious - but also wonder about permanent damage I may have due to my illness, such as liver or kidney damage. I still have some remnants of my illness in my eyes and voice, though I feel totally healthy otherwise.
