The kit comes with a test cartridge, a swab, and a buffer solution. To use the kit, you first collect a nasal swab sample. Then, you add the swab to the buffer solution and mix it well. Finally, you add the buffer solution to the test cartridge and wait for 15 minutes.

If the test is positive, two lines will appear on the test cartridge. If the test is negative, only one line will appear.

The Longsee test kit is a quick and easy way to test for COVID-19. It is important to note, however, that it is not as accurate as a PCR test. If you have a positive test result on the Longsee test kit, you should follow up with a PCR test to confirm the result.
