Washington state authorities have recalled an estimated 12,000 COVID-19 testing kits due to possible contamination.
The state’s Department of Health said in a recent news release that it was notified by parties at the University of Washington Medicine of a possible “quality control issue” in connection with a “small number” of vials of a special fluid used to keep specimens from COVID-19 nasal swabs intact during transport. Called viral transport media (VTM), the fluid in some of the vials had an unusual color.
