Stock Photo - 03 March 2021, Saxony, Leipzig: In a PCR laboratory of MVZ Labor, the head of the infectious disease PCR department, Dr. Katja Sänger, prepares swabs from patients for SARS-CoV-2 diagnostics on an analytical device at the safety workbench. The laboratory, which is part of the Limbach Group, processes around 10,000 PCR samples per week for the detection of SARS-CoV-2 for hospitals and general practitioners. Currently, virus variants with an increased risk potential are also diagnosed, including the British B.1.1.7 variant, which is currently particularly widespread, but also the South African and Brazilian virus variants.
