HELENA, Montana — States frustrated by private laboratories’ increasingly long turnarounds for COVID-19 test results are scrambling to find ways to salvage their testing programs.Montana said Wednesday that it is dropping Quest Diagnostics, one of the nation’s largest diagnostic testing companies. The Secaucus, New Jersey-based company had done all the state’s surveillance COVID-19 testing — drive-thru testing that moves from community to community to help track COVID’s spread. But it told state officials last week that it was at capacity and would be unable to accommodate more tests for two or three weeks.
