To do a COVID-19 test at home (using a common rapid antigen test kit), follow these general steps:
- Wash your hands thoroughly with soap and water.
- Prepare a clean surface and place all test kit items on it (swab, test card or cassette, and liquid/dropper tube).
- Blow your nose to clear your nostrils.
- Open the swab packaging carefully, touching only the handle.
- Insert the swab into one nostril about 1/2 to 3/4 inch (about the size of the tip of your pinky) and rotate the swab around 5 times against the nasal wall.
- Repeat the swabbing in the other nostril with the same swab.
- Insert the swab into the tube with liquid and swirl it around for about 15 to 30 seconds to mix.
- Squeeze the sides of the tube to extract liquid from the swab and then remove the swab.
- Place a cap or nozzle on the tube, then put the recommended number of drops (often 3-6) onto the test strip or cassette.
- Set a timer for the specified waiting time (usually 15 minutes).
- Read the result: a line at the control (C) indicates the test is valid; a line at the test (T) means a positive result. No line at C means the test is invalid.
It is important to carefully read and follow the instructions included with the specific test kit, as exact details may vary between brands. Do not read the result after the maximum stated time, as it may be inaccurate.
