Nashville-based IQuity has officially released its first RNA-based blood test IsolateMS. Using machine-learning technology, IQuity developed a tool that helps doctors rule in or rule out a suspected multiple sclerosis diagnosis at the earliest sign of symptoms. IsolateMS delivers results with more than 90 percent accuracy within seven days. This test is 12 years in the making, originally developed at Vanderbilt University, and licensed through the Vanderbilt Center for Technology Transfer and Commercialization.
