When reliable testing for COVID-19 became a national priority earlier this year, one company in Huntsville was already set up to take on a leading role.
Diatherix was equipped to offer testing through its cutting-edge technology, and it was able to do so in a way conducive to effective treatment of the virus by providing same-day results.
An infectious disease clinical laboratory located in the HudsonAlpha Institute for Biotechnology, Diatherix provides testing capabilities for doctors’ offices, hospitals, reference labs and nursing homes.
In a recent conversation with Yellowhammer News, Diatherix president Jennifer Cart described her company’s role in confronting the coronavirus pandemic.
“We essentially provide a laboratory service so that physicians can more accurately diagnosis their patients,” said Cart. “We are squarely seated in this rapid, providing of same day results for the specimen so we are giving very timely and accurate information in infectious diseases.”
Having been in business since 2008, that role is reflected in the company’s name, which Cart explained represents “where diagnostics meet therapeutics.”
While conventional laboratories provide more generalized testing on a broader range of specimens, Diatherix’s more tailored focus allowed it to rise to the occasion on the front-end of the COVID-19 outbreak in March.
“We are very uniquely specialized in infectious disease, and our proprietary technology is a very high-throughput multiplex that makes us able to run a high volume of specimens with multiple results,” outlined Cart.
The team at Diatherix began its assessment of the coronavirus in December 2019, according to Cart. This early evaluation allowed the company to hit the ground running when the need arose for mass testing.
“Because we are focused on infectious disease, we are always monitoring for emerging pathogens, so this was not our first emerging pathogen,” she remarked. “We have seen in the past MERS, which came from UAE, the Middle East. We are always looking and watching, and then we make determinations whether or not we think it is going to be a player in the United States such that we would need to develop the assay.”
That understanding brought about a testing procedure, or assay, in record time.
“In our history this was probably our fastest launch of a new assay because we actually have it as part of a very complex group of other viruses so we could right off the bat determine if it was COVID or flu right out of the gate,” said Cart. “We already had that capability in March. Everybody has been talking about having that now, having it for the fall. We have already been positioned for that and been able to run results since then.”
Since March, there have been 8.8 million coronavirus cases in the United States. Alabama has seen a little over 160,000 confirmed cases in that same period.
The volume of work at Diatherix has matched the country’s case counts throughout the year.
“From March through July, it was on a very rapid, accelerated incline,” Cart noted. “We then hit a bit of a stabilization in August and September. We are back to what I would not say as rapid of an incline, but a steady incline.”
The nation’s peak for new case counts occurred July 24 when 74,710 new cases were registered with the Center for Disease Control (CDC). Reported daily cases dipped to 23,301 on September 8. The United States hit a new daily high on October 24 when the CDC registered 83,851 new cases.
Without revealing specific internal data, Cart estimates that Diatherix has averaged around 100,000 tests per month, a figure which puts the company on track to process more than one million coronavirus tests by the end of 2020.
Heavily reliant on overnight shipping, specimens have arrived in Huntsville from providers across the country.
As an example, Cart recalled the work Diatherix did for numerous drive-thru testing sites in states like Michigan, Tennessee and Florida. The process, she said, was no different than a normal physician’s office except they received 300 to 400 specimens per day from places which would normally send them five.
To handle the volume, the layout of the facility had to change. The basement was cleared, and packages were routed down there for opening and specimen transport to the labs.
Even with state-of-the-art equipment and proprietary testing processes, Cart points to a single aspect of the company which has allowed Diatherix to weather an unprecedented strain this year.
“People are our greatest asset,” she emphasized.
Since the beginning of the year, Diatherix has hired 100 new employees, placing the company’s personnel total at 250.
“It is all hands on deck,” said Cart. “First of all, our lab, our R&D team and our client services has been consistently working since developing the test and running the test. There have been no breaks. It’s a pounding intensity that has been relentless and has not stopped.”
The paperwork that accompanies such a high volume of specimens has been daunting. Employees were called to fill multiple roles to handle more than 20,000 documents received daily.
“We had people outside of their normal job, and everyone still had their normal job to do, doing that just so we could get the results out,” explained Cart. “Because we know how important it is to have the same day results at the time when many labs are doing five, six, seven, ten days waiting for the results, which becomes less useful information to the physician once it gets past the date of collection.”
A graduate of the University of Florida, Cart mentioned to one of Diatherix’s employees, who was a native Alabamian, how impressed she was with the way the team was handling the increased workload during the COVID crisis.
“She replied to me, ‘That’s what we call hard stock,’” recollected Cart.
That can-do attitude prevalent among Diatherix’s employees has made quite an impression on the company’s leader.
“It brings tears to my eyes to think about what our employees have given up to be there every day, to do what we need to do not only for the company but for the state and for the country in the pandemic,” Cart remarked. “Their kids are at home getting home-schooled by their spouse or their with grandparents. We have done everything we can to support them but ultimately they are really carrying this company and carrying us forward. It will be something that, in my career I’ve learned a lot as a leader, but the biggest impact to me is how I’ve seen these employees and the people. I can’t even describe it. It is hard stock is the best way to put it.”
The United States has seen a surge in coronavirus infections during October, and several European countries are renewing lockdowns.
A forward-looking approach has helped Diatherix prepare for whatever is next in the fight against COVID-19, according to Cart.
“We have already been making changes,” she outlined. “As part of our normal process, with viruses in particular, viruses can mutate. They call it antigenic shift. We are always blasting the viruses, not just SARS-CoV-2, but influenza A, B, anything that essentially could have viral antigenic shift, and watching for that. We are always monitoring for the need to put in a different sequence or different target for our assay to be even more robust.”
As Cart and her team move forward, they see no signs of letting up, themselves.
“The ramp up has been all-consuming but we have been able to produce same-day results as we receive our specimens,” Cart concluded. “In today’s time, with everybody targeting 48 hours, the fact that we can essentially provide the results the day we receive them is still a feather in the Diatherix cap in comparison to all the other labs.”
