Falls die Antigentests zur Anwendung durch Laien jetzt endlich zugelassen werden, dann kann's auch wieder an die Platten gehen, wenn man sich nicht von Formulierungen wie "Zudem sind die Antigentests nicht so zuverlässig wie PCR-Tests - es kann sowohl zu falsch positiven als auch falsch negativen Ergebnissen kommen." irritieren lässt.
PCR-Tests: "Nonetheless, our findings reinforce the need for repeated testing in patients with suspicion of SARS-Cov-2 infection given that up to 54% of COVID-19 patients may have an initial false-negative RT-PCR" 1)
"A systematic review of the accuracy of covid-19 tests reported false negative rates of between 2% and 29% (equating to sensitivity of 71-98%), based on negative RT-PCR tests which were positive on repeat testing" 2)
Und aus 3) "Over the 4 days of infection before the typical time of symptom onset (day 5), the probability of a false-negative result in an infected person decreases from 100% (95% CI, 100% to 100%) on day 1 to 67% (CI, 27% to 94%) on day 4. On the day of symptom onset, the median false-negative rate was 38% (CI, 18% to 65%). This decreased to 20% (CI, 12% to 30%) on day 8 (3 days after symptom onset) then began to increase again, from 21% (CI, 13% to 31%) on day 9 to 66% (CI, 54% to 77%) on day 21."
