Robust Response of the Clinical Laboratory to the COVID-19 Pandemic despite Significant Challenges

Abstract

Abstract Background Clinical laboratories immediately provided rapid, reliable, and high-throughout diagnostic testing for COVID-19, which was an essential component in combating the pandemic. As the pandemic evolved, the clinical laboratory was faced with additional challenges. However, there are limited studies on the impact of the pandemic on the clinical laboratory over the past 3 years. Methods The American Association for Clinical Chemistry (AACC) sent 8 surveys over a 32-month time period to international clinical laboratory leadership asking questions about COVID-19 testing, supplies, staffing, and lessons learned. Results There were a total of 191 unique respondents: 133 laboratories in the US and 58 laboratories from 37 other countries participated. By May 2020, more than 70% of laboratories offered COVID-19 diagnostic testing with average turnaround times ranging from 1 to 24 h. Daily COVID-19 testing volumes peaked in January of 2022 at a median of 775 tests per day. Throughout the pandemic, supplies and staffing concerns increased. In most of the 8 surveys, 55% to 65% of laboratories reported they were unable to obtain supplies. Obtaining reagents and test kits was the most problematic. Staffing challenges continue to be a significant concern and most laboratories have struggled hiring testing personnel. Conclusions Survey results were utilized to demonstrate the impact of the pandemic on the clinical laboratory community, and importantly, findings were presented to the White House Coronavirus Taskforce. Overall, the clinical laboratories had a robust response to the COVID-19 pandemic, and despite ongoing and evolving challenges, continue to provide rapid diagnostic testing.
