The problem is that the tests have to be accepted by the institution prior to the person allowed back to work or school they dictate what test you take when and where and how many times
If your work says they follow the CDC guidelines then you don't have to take a test if you wait 10 days after symptom onset. CDC said (haven't checked in the last month though) if you want to return earlier you need a neg test. In my comment above I said I waited 21 days, but only because I work from home and had no need to go into a local office for anything until the 21st day. YMMV.
