FROM INTERNAL BENEFIT TO EXTERNAL BUSINESS As a clinical reference laboratory, Children’s Colorado offers subspecialized esoteric assays that few institutions have access to. This means other institutions across the nation send samples for testing, and Children’s Colorado delivers the service. As the first hospital in Colorado to validate and offer a SARS-CoV-2 assay, the lab expanded that model to help serve the COVID-19 testing needs of hospitals and other clients in Colorado and neighboring states. With five separate platforms, including two Abbott highthroughput devices, the lab takes a diversified approach to testing patient specimens. The strategy has allowed the team to work through concerning supply chain challenges while still maintaining its value proposition: a high-quality test result within 24 hours. WASHES AS A WORKAROUND Early on, inventory was tight for many supplies — including the typical flocked swabs. Although the hospital now has the numbers it needs, it did temporarily implement a swab alternative. “With children, we often do nasopharyngeal washes, which is where you squirt some saline into the nose and then collect it as the specimen,” says infectious disease specialist and Children’s Colorado Microbiology Lab medical director Samuel Dominguez, MD, PhD. “You don’t need swabs for those because it’s a different procedure, and you achieve the same results. It was a great workaround for some patients.” HIGH-THROUGHPUT MOBILE SPECIMEN COLLECTION The fashioning of two drive-thru collection sites, one at Anschutz Medical Campus in the Denver metro area and the other at Children’s Hospital Colorado, Colorado Springs, allows for safe and efficient specimen collection that conserves the consumption of personal protective equipment used by healthcare workers. A third site will open soon at Children’s Hospital Colorado, North Campus in Broomfield, along with a fourth site at Children’s Hospital Colorado, South Campus, in Highlands Ranch. Access to these collection sites is by appointment only, and they are not open to the general public. Rather, they fundamentally serve pediatric patients in the community, as well as healthcare workers. STUDYING SERO-EPIDEMIOLOGY The pathology lab at Children’s Colorado was the first in Colorado to begin collecting convalescent plasma from recovered COVID-19 patients and manufacturing it for transfusion under FDA emergency IND protocol. Convalescent plasma contains antibodies to SARS-CoV-2 that, when transfused into a patient with COVID-19, are believed to help them recover by boosting their immune system. But for reasons unknown, some recently recovered patients don’t seroconvert — meaning they don’t develop detectable antibodies. To avoid unnecessarily collecting plasma from donors, the transfusion medicine team now performs antibody testing prior to collection. • Visit Q: Magazine online to read more about our COVID-19 research and innovation efforts.
