COVID-19 pandemic has brought many non-traditional medical laboratory participants into UBC’s CMPT proficiency testing program

When Canada’s British Columbia Center for Disease Control (BCCDC) saw the increasing demand for of COVID-19 tests and responsibilities headed its way, it reached out to a well-regarded proficiency testing program for help. The public health agency turned to the University of British Columbia’s (UBC) Clinical Microbiology Proficiency Testing (CMPT) Program.

Since the early 1980s, UBC’s CMPT program, led by medical microbiologist Michael Noble, MD, has provided external quality assessment (EQA) for clinical microbiology and water testing laboratories. This includes providing biological samples related to:

But COVID-19 changed everything.

“Typical of every jurisdiction in North America and probably around the world, BCCDC got swamped beyond swamped,” said Noble, the Clinical Microbiology Proficiency Testing (CMPT) program’s first and current Chair, in an exclusive interview with Dark Daily. “The increase was 10-fold, and they were unable to provide all the services they wanted to do. And since I was already running a proficiency testing program across the province, they asked if I would provide that service for COVID-19 for laboratories that were doing the testing.”

He began his career as a medical microbiologist but soon focused on laboratory quality management. Within the Department of Pathology and Laboratory Medicine, Noble co-developed the Clinical Microbiology Proficiency Testing (CMPT) program in 1983, a program he still chairs but will soon pass on to a new leader.

CMPT’s Proficiency Testing Serves Labs Worldwide

UBC’s CMPT external quality assessment (EQA) program serves all medical laboratories in British Columbia, as well as other labs in Canada, Europe, South America, and the Caribbean. Just over 200 laboratories currently participate in the program. More labs participated in past years, before lab consolidation affected CMPT and other programs as well, Noble said.

CMPT’s proficiency testing ensures that participant laboratories that have been provided with simulated samples can perform tests at the “level of quality and competence required,” notes UBC’s CMPT website.

“Samples are complex, highly realistic, and clinically relevant. CMPT samples contain host elements as well as targeted pathogens,” Noble explained on his blog, “Making Medical Laboratory Quality Relevant.”

COVID-19 Brings Non-Traditional ‘Laboratories’ to CMPT’s Proficiency Testing Program

UBC’s proficiency testing for SARS-CoV-2, the coronavirus that causes the COVID-19 infection, differs from other CMPT programs. That’s due to new participants that entered the laboratory testing program during the COVID-19 pandemic that are performing COVID-19 testing in non-traditional locations, Noble stated.

“In our proficiency programs, we had mainly been dealing with traditional clinical laboratories,” Noble explained. “But now, we find people doing COVID-19 testing—even though defined as medical laboratories—who are working in airports, or in tourism, or the movie industry, or forestry. They may never have worked in an actual clinical laboratory. So, it’s a very different style of proficiency testing. There has been a lot of handholding, teleconferences, discussions, and one-on-ones with that group,” Noble said.

UBC’s COVID-19 Proficiency Testing Program for PCR and rapid antigen tests recently began serving public and private facilities. Three samples per shipment are being released by UBC every two months.

Participant laboratories receive viral material that “simulates typical samples.” They need to demonstrate proficiency by performing the test and reporting it as positive, negative, or inconclusive.

“Our product is derived from a pure culture of a single strain of SARS-CoV-2, and it appears to be effective for all targets,” Noble stated.

Detecting COVID-19 by Gargling and Rinsing

UBC’s program typically offers simulated sampling for detection of SARS-CoV-2 in nasopharyngeal swabs. However, the BC Center for Disease Control’s (BCCDC) mouth rinse and gargle sample collection for diagnosis of COVID-19 also is available and widely used in Canada, Noble said.

In fact, a Vancouver-based study published in the Journal of Clinical Microbiology, titled, “Self-Collected Saline Gargle Samples as an Alternative to Health Care Worker-Collected Nasopharyngeal Swabs for COVID-19 Diagnosis in Outpatients,” found mouth rinse testing just as effective as nose swab samples in detection of the novel coronavirus, the Vancouver Sun reported.

Qualitology is Imperative to Medical Laboratories

In his career, Noble transitioned from medical microbiology to qualitology, which he describes as “the study of quality in the medical laboratory.”

In stressing the importance of laboratory quality testing, Noble describes the possibility of laboratory testing going awry and leading to a microbiological public health emergency.

“What happens if there’s a stool sample, and someone misses the presence of Campylobacteriosis in the stool? What happens if that’s part of a foodborne disease and there’s an outbreak in the city and samples are being missed? How many people will be impacted as a result of that error?” he asked.

University of British Columbia Endows a Chair for Laboratory Quality Management

Noble says UBC’s Program Office for Laboratory Quality Management (POLQM) has involved organizations worldwide and certified more than 500 people.

“The impact they have over their laboratories has been huge. Maybe that would have happened without us. But we were a part of that. And our impact is not one laboratory or one city or one province but widespread, and that’s a real and enriching experience to have,” he said.

But now it is time for him to move on. Noble secured (through UBC), a benefactor to establish the endowed Chair for Laboratory Quality Management. The family of the late Donald B. Rix, MD, a Canadian pathologist and philanthropist, gave $1.5 million (matched by the university) to create the Associate Professor (Grant Tenure) Donald B. Rix Professorship in Laboratory Quality at UBC, Department of Pathology and Laboratory Medicine.

Long-serving pathologists and medical laboratory professionals may remember that Rix was the founder and chair of MDS Metro Laboratory Services (now known as LifeLabs Medical Laboratory Services). It grew into the largest private medical laboratory in Western Canada.

Referring to this endowed new Chair for Laboratory Quality Management, Noble said, “I think this is the first named position of laboratory quality in North America.” UBC has commenced reviewing applications for the position, which is expected to be effective in January 2022. Pathologists and clinical laboratory scientists with appropriate qualifications and interest in this position should contact Dr. Noble’s office at the University of British Columbia Faculty of Medicine.
