NEW YORK (TheStreet) -- Shares of Great Basin Scientific (GBSN) skyrocketed 54.83% to $5.48 in afternoon trading Wednesday after the molecular diagnostic company announced that the U.S. Food and Drug Administration (FDA) has granted clearance to the company for its molecular diagnostic test for Group B Streptococcus (GBS).
This the second Great Basin assay that the FDA has cleared, the company said in a statement. Its first test, for Clostridiumdifficile, or C. diff, was approved in May 2012.
Great Basin intends to debut the GBS assay commercially in the second quarter of 2015.
