NEW YORK (GenomeWeb) – NanoString Technologies said today that it has calculated preliminary total revenue of approximately $25.9 million to $26.9 million for the third quarter of 2017, which includes product and service revenue of approximately $16.9 million — a significant shortfall from the firm's previous guidance of $19.5 million to $21.5 million from products and services.

NanoString President and CEO Brad Gray attributed the discrepancy to softness in the company's instrument and consumable sales over the quarter.
