Inside the Lab: Processing COVID-19 Tests at BC Haley Hockin Special Projects Editor

On March 11, 2020, Boston College closed its campus due to COVID-19. During the closure, the University established an on-campus laboratory to test for the virus. Nearly one year later, students test positive for the virus every day on campus, but the lab that discovers it is far from ordinary. “From what I understand, a lot of other universities are actually envious of what we have because they don’t have the capacity to test on site and then they’re dependent on other providers,” Andrea Kirmaier, research assistant professor and the acting technical director of the on-campus lab, said. “Some states have turnaround times of days or even weeks, which is really bad for a college-community setting.” The Boston College Microbiological Laboratory (BCML) processes the BC community’s COVID-19 tests. First certified in September, the lab now has the capacity to process 1,000 to 1,500 test samples daily, according to Welkin Johnson, chair of the biology department and head of the Johnson Lab.

The Testing Process

The BCML, which is housed in the Johnson Lab, uses RT-PCR tests, which detect the presence of the SARSCoV-2 virus with PCR testing instruments normally used to test for the seasonal flu virus, according to the Centers for Disease Control and Prevention. “[PCR tests are] basically the gold standard for detecting viruses,” Johnson said. The lab was first certified by the Commonwealth of Massachusetts to process tests on BC’s campus in September. The Broad Institute is the other lab that processes the BC community’s test samples. Before the on-campus lab was certified, the Broad Institute processed all of the BC community’s test samples. The process for the on-campus lab begins in either the Margot Connell Recreation Center, University Health Services (UHS), or Conte Forum, where community members have their noses swabbed. The tests are then picked up by graduate student runners, according to Johnson. “What they do is, three times a day, they go on a run, where they stop at the rec center, at athletics, and at University Health Services and they pick up the tubes with the swabs and transport them back to the lab,” he said. There are three labs that are a part of the BCML. The first lab is where all the substances required for the PCR are mixed and added to plates, Johnson said. Later, in another lab, the DNA from the test sample will be added to this mix to create a complete reaction. Due to contamination issues that could lead to false positives, the patient test samples are never brought into the first lab. “Meanwhile, in the 2nd lab, a buffer [a solution that is able to neutralize strong acids and bases and resist a pH change] is added to the patient swabs so that any virus present on the swab will diffuse into the buffer,” Johnson said in an email to The Heights.

Welkin Johnson, chair of the biology department and head of the Johnson Lab, said that while the University is currently not planning to enter into a lockdown, the administration monitors case numbers daily, as well as consults with leadership of other universities in the area, to ensure it is prepared to shut down if it becomes necessary or is mandated by the state. “Right now, I don’t believe it will be necessary as long as the numbers nationally and on campus keep heading in the right direction,” he said. Since Feb. 1, 205 undergraduates have tested positive for COVID-19, according to the University’s COVID-19 dashboard. BC also reported a record high of 139 students in isolation on Feb. 17, eclipsing a first semester high of 87 on Nov. 27. Many students are currently in quarantine after being in close contact with students who tested positive, though BC does not release the number of students in quarantine. Rumors of a University-wide quarantine circulated after the rise in cases and isolations. A fake email attributed to Executive Vice President and Acting Vice President for Student

Affairs Michael Lochhead and Provost and Dean of Faculties David Quigley, which falsely claimed that the University would go into a two-week quarantine starting last Friday, circulated on social media and in group chats last Thursday. Lochhead said in an email sent to students on Thursday that the University would not enter into a two-week lockdown on Friday. “Contrary to rumors and an image of a fraudulent email that has been shared on social media, Boston College is not going into lockdown on Friday,” he wrote. Johnson, who led the University’s efforts to create a state-certified laboratory to test COVID-19 samples, said that there is likely not a certain threshold of cases that would push BC into a lockdown. A spike, for example, could lead to a sharp increase in the percentage of positive cases on campus, he said, but that likely wouldn’t lead to a shutdown unless the numbers stayed that high or continued to rise. “I know there’s not just some magic number,” Johnson said. In the pre-semester weeks of the fall semester, when the University tested all of its undergraduates for COVID-19 upon their arrival to campus, only nine students tested positive. By comparison, 76 students tested positive during the same pre-semester period in the spring semester, according to BC’s COVID-19 dashboard.
