"Clinical test revenue grew 25% in 2013, with notable strength in our Commercial Clinical Xpert reagents which grew 22%," said John Bishop, Cepheid's Chairman and Chief Executive Officer. "We also placed a record number of GeneXpert systems in 2013, with strength in both our commercial and HBDC businesses, demonstrating the impact of our rapidly expanding Xpert test menu and global sales footprint."
Continued Bishop, "Adoption of our high throughput Infinity system increased with a record 52 shipments in 2013, including 23 in the fourth quarter, further highlighting Cepheid's position as a platform consolidator within the molecular diagnostics market. With a menu of 14 tests and growing, we believe the innovative GeneXpert system is the most compelling choice for labs of all sizes looking to leverage accurate and fast diagnostics without the costs and complexities traditionally associated with molecular technologies."
