The updated test now includes additional susceptibility testing and clinical interpretive breakpoints that are compliant with 2019 European guidance.

Of the 27 companies in the index, 12 firms' share prices retreated last month, 14 companies' stocks increased, and one firm's share value was flat.

Other big gainers last month included Accelerate Diagnostics and Natera, and share prices of 23 of the 27 companies in the index increased month over month.

The revenue increase was driven primarily by an increase in the sale of consumable test kits, and the firm added 75 commercially contracted instruments during Q1.

Many diagnostic firms saw gains in their stock prices last month as Invitae and NantHealth also saw healthy increases.

The company has adopted a reagent rental approach which it believes supported the placement of 133 instruments in the quarter.

The 360Dx Index was up 12 percent last month as shares of Accelerate Diagnostics, Veracyte, and Exact Sciences each improved more than 40 percent month over month.
