I've taken them at home, then sent my child to the doctor for medication where their rapid didn't show up until an overnight proved that it was strept. This has happened more than once. these tests are very accurate. will buy again.
I ordered this product for a sore throat that went on for over a week. Local doctors are not doing cultures right now because of COVID 19. Instructions very easy to follow. Test results easy to read (negative). Superfast shipping. Highly recommended!!
