My girlfriends family just had a round with Covid.
Started with 2 in the family waking up with fever. Took home test- both positive. Brought to the hospital for PCR test- both positive and hospitalized.
The three others in the house test negative on the home test.
They also go to the hospital that day to take PCR- all negative.
They go into 14 days home quarantine.
6 days into the home-quarantine 1 of the remaining 3 gets a fever. Takes the home test which shows up positive. Taken to the hospital for PCR which is positive and hospitalized.
The 2 other negative on home test.
3 more days goes by when 1 of the 2 remaining gets a fever. Takes the home test- positive. Off to the hospital where PCR is positive and she gets hospitalized.
Last person still showing negative home test.
13 days after the first case in the house, and 4 days since the last case, one person in the house still going strong with no symptoms and negative home test.
I would say these home tests are worth every single bath even if they are not as accurate as the PCR
