The collection of data on SARS-CoV2 tests is central to the assessment of the infection rate in the context of the COVID-19 pandemic . At the Robert Koch Institute (RKI), data collected from various laboratory data recording systems are consolidated . First, this article aims to exemplify significant aspects regarding test procedures . Subsequently the different systems for recording laboratory tests are described and test numbers from the RKI test laboratory query and the laboratory-based SARS-CoV2 surveillance as well as accounting data from the Association of Statutory Health Insurance Physicians for SARS-CoV2 laboratory tests are shown.Early in the pandemic, the RKI test laboratory query and the laboratory-based SARS-CoV2 surveillance became available and able to evaluate data on performed tests and test capacities . By recording the positive and negative test results, statements about the total number of tests and the proportion of positive test rates can be made . While the aggregate test numbers are largely representative nationwide, they are not always representative at the state and district level . The billing data of the Association of Statutory Health Insurance Physicians can complement the laboratory data afterwards . In addition, it can provide a retrospective assessment of the total number of SARS-CoV2 numbers in Germany, because the services provided by statutory health insurers (around 85% of the population in Germany) are included . The various laboratory data recording systems complement one another and the evaluations flow into the recommended measures for the pandemic response.
