Pandemic Demand for SARS-CoV-2 Testing Led to Critical Supply and Workforce Shortages in U.S. Clinical and Public Health Laboratories.

COVID-19 has brought unprecedented challenges to clinical and public health laboratories. While U.S. laboratories have continued striving to provide quality test results during the pandemic, the uncertainty and lack of supplies became a significant hurdle, hindering day-to-day laboratory operations and the ability to increase testing capacity for both SARS-CoV-2 and non-COVID-19 testing. In addition, long-standing laboratory workforce shortages became apparent, hindering the ability of clinical and public health laboratories to rapidly increase testing. The American Society for Microbiology, the College of American Pathologists, the National Coalition of STD Directors, and the Emerging Infections Network independently conducted surveys in 2020 and early 2021 to assess the capacity of the nation's clinical laboratories to respond to the increase in demand for testing during the COVID-19 pandemic. The results of these surveys highlighted the shortages of crucial supplies for SARS-CoV-2 testing and supplies for other routine laboratory diagnostics, as well as a shortage of trained personnel to perform testing. The conclusions are based on communications, observations, and the survey results of the clinical laboratory, public health, and professional organizations represented here. While the results of each survey considered separately may not be representative of the entire community, when considered together they provide remarkably similar results, further validating the findings and highlighting the importance of laboratory supply chains and the personnel capable of performing these tests for any response to a large-scale public health emergency.
