I took a test on the 22nd and have not heard back one way or another on my results (for employer). They sent mine to Quest in California and Im paranoid too, even though I was passing home tests on my first void of the morning.

My company tests the first round of people on the 5th and did not notify them of pass/fail until the 15th, so Im saying 7-10 days max and then if you dont hear back, youre in the clear.
