What does a faint line on a Covid test mean?

This is because relatively large amounts of virus need to be present for the antibodies in the test to react to the viral proteins. A faint, slow-to-appear line could still represent high levels of virus, meaning that if you can see any line at all, you are still highly likely to be infectious.

How to get through COVID faster?

What medications can I take to relieve the symptoms of COVID-19?
