The one I bought had 2 tests in the box, and I only used one before heading to the dentist, as I have a mild cough. Didn't cough at the dentist's so now I'm wondering if it's the dust in my house. The dental staff are keeping their space extraordinarily clean. My test was the Abbott brand. I am thinking of buying several boxes in advance so that five of us can be tested on the day of my mother's birthday in order to decide whether or not we should eat together, maskless and indoors.
