National Pandemic Centre SARS-CoV-2 (COVID-19) test statistics

The National Pandemic Centre (NPC) at Karolinska Institute ceased operations of high throughput PCR diagnostics on 2020-12-21.

The data presented here is no longer updated but is kept for historical reference.

KI Press Release

The dataset visualised in the graphs on this page is available on SciLifeLab’s Blobserver. The numbers reported here were compiled automatically and, as such, might not correspond to the numbers reported through other sources for different reasons.

Total NPC test numbers

The total number of SARS-CoV-2 (COVID-19) tests conducted at the national Pandemic Centre (NPC) since the start of the pandemic, separated according to whether the results were positive, negative, or invalid/inconclusive.

The National Pandemic Centre (NPC) was a facility for SARS-CoV-2 (COVID-19) testing established within the Centre for Translational Microbiome Research (CTMR) at Karolinska Institutet (KI)/SciLifeLab. At the end of March 2020, the large-scale microbiome research lab was quickly converted into a centre to assist Sweden with analysing SARS-CoV-2 tests. This was made possible by a donation from the Knut and Alice Wallenberg Foundation (KAW) and a previously established collaboration with MGI Tech in Shenzen, China. The NPC initially helped to expand the RNA-extraction capacity at Karolinska Universitets laboratoriet. However, it quickly expanded into a facility that increased the testing capacity across all regions of Sweden.

The final capacity of the National Pandemic Centre at KI/SciLifeLab was approximately 10,000 tests per day. The results were typically returned within 24 hours of the sample arriving to the lab. NPC exclusively performed PCR-based analyses, not serological (antibody-based) analyses.
