Put to the Test

Even before the COVID-19 pandemic unfolded in Maryland in March 2020, Mike Humphrys, MSc, and his Microbiome Service Laboratory (MSL) team got to work on addressing the novel coronavirus. The mission: Transform a genomics lab into a large-scale COVID-19 testing platform.
鈥淲e were discussing COVID-19 testing in late February and early March, and we bought the supplies we鈥檇 need to kind of play around with the test and figure it out,鈥� said Humphrys, director of MSL, which is part of the Institute for Genome Sciences (IGS) at the 91大神 School of Medicine (UMSOM).
鈥淥nce you have a swab sample in the lab, you have to extract nucleic acids 鈥� DNA and RNA 鈥攄o a couple of purification steps, and then do the actual test. We use programmable robots for that, so we took the robots and built an assembly line, then bought a bunch more robots with state funding and programmed all of them to run just COVID tests.鈥�
Once the system was functional, the lab was capable of processing 1,000 samples a day, but it wasn鈥檛 receiving that many because of the initial struggles setting up COVID-19 test collection. After those front-end issues resolved and tests started pouring in, the lab could process 10,000 or more samples a day coming from various collection sites around Maryland and other nearby states.
鈥淥ur capabilities have progressed a lot since the start,鈥� Humphrys said. 鈥淒uring the Thanksgiving and Christmas surges, the system was able to adjust to about 1,000 to 1,200 samples an hour, just churning through them. It was pretty cool to see it in action.
鈥淚 think the most we鈥檝e done recently is 11,000 samples in a 10-hour day,鈥� he added. 鈥淚 don鈥檛 think that at any time along the way we鈥檝e really hit our capacity or been totally overloaded.鈥�
Humphrys says the MSL team worked long hours, with some staff working on-site and some remotely. It was common for employees to work 12- to 18-hour days, six or seven days a week. Because of these yeoman efforts and the success of the testing initiative, the MSL team was named a 91大神, Baltimore (UMB) Champion of Excellence.
IGS collaborated with 91大神 Pathology Associates, UMB, the state of Maryland, and the city of Baltimore on the project, and IGS director Claire Fraser, PhD, who also is the Dean鈥檚 Endowed Professor at UMSOM, called the MSL team鈥檚 work 鈥渆xtraordinary.鈥�
鈥淭he Microbiome Service Laboratory has overcome many technical and logistical challenges to make this testing program a success,鈥� Fraser said. 鈥淲ith Mike鈥檚 calm and steady leadership and the staff鈥檚 work ethic, ingenuity, and collaborative approach, the lab has inspired all of those involved in this effort across campus and across the state.鈥�
In normal times, MSL supports research studies designed to characterize the bacteria that compose the human microbiome, essentially anything on Earth that is inhabited by bacteria and microorganisms. And while most of the nearly 40-person team is still working on COVID-19 research 鈥� including the study of coronavirus variants in positive test samples 鈥� a few have shifted back to other research studies.
No matter the project, Humphrys says his team is up to the challenge, and he appreciates MSL鈥檚 recognition as a UMB Champion of Excellence.
鈥淓verybody has worked tirelessly and selflessly to get this done, and I鈥檓 proud of them all,鈥� he said. 鈥淩obotics and molecular biology are familiar to us, because we are all researchers. This clinical component was very new to us, but we basically shed our previous lives and switched over to combat this virus. And that鈥檚 pretty remarkable.鈥�
