Supporting this idea, scientists in Dr. Drains lab found that samples taken from people with Covid-19 who had very low levels of the virus (below what a rapid test can detect) were unable to infect cells in a petri dish. PCR tests that hunt out parts of viral genetic material (RNA in the case of SARS-CoV-2) in our bodies and amplify it so we can detect it are extremely sensitive and can even pick up the presence of a few viral fragments.
