External quality assessments for SARS-CoV-2 genome detection in Austria : A comparison of the first postpandemic round with results from the pandemic era.

Overall ratios of true positive results were below the mean of all results during the pandemic but were similar to the first round of the pandemic. A lower post-pandemic true positive ratio was associated with specific laboratory types and assay formats, particularly for samples with low concentration. The EQAs will continue to monitor the laboratory performance to ensure the same quality of epidemiological data after the pandemic, even if vigilance has decreased.
