NEW YORK (GenomeWeb) — OpGen said today that it expects to post a 36 percent drop in its third quarter revenues amid a drop in sales of its QuickFISH rapid pathogen diagnostic products.

For the three months ended Sept. 30, OpGen reported preliminary unaudited revenues of $550,000 versus $750,000 in the same period last year — a decline the Gaithersburg, Maryland-based company attributed to lower QuickFISH revenues.
