This was announced by Berlin's Senator for Health Ulrike Gote (Green Party) on Friday (Jan. 21, 2022) to rbb Inforadio. Gote explained that if a person were to test positive with a rapid test done by themselves, but does not show any symptoms, "it will most likely be sufficient to only take an additional rapid test at a testing center." The person would then also receive a corresponding certificate. A rapid test is also normally sufficient to 'test yourself clear' at the end of an infection phase. PCR tests would then only be necessary for people who work in places such as retirement homes, nursing homes and hospitals. In recent days, there had been long queues with hours of waiting time at many PCR test sites.
