Comparison of the flow-normalized SARS-CoV-2 RNA values (mean of the targets N1 and N2) measured by dPCR between TNA extracts with PCR inhibitor removal and five-fold dilution (PIR+D) (blue, circle) or undiluted TNA without PIR (w/o PIR+D) (red, square) derived from Ruhleben (n = 21) and Waßmannsdorf (n = 19). The data show a comparative analysis of all samples (2–3 per week) from 4 February 2024, until 27 March 2024.
