Fully Automated Gram Stain Launched

A fully automated Gram Stain Kit has been launched globally on the BenchMark Special Stains platform.

The Gram Staining Kit aids pathologists in the most basic classification of bacteria into Gram-positive and Gram-negative bacteria in fixed tissue samples. Gram stain classification is clinically useful as it provides an initial indication of the nature of a patient's infection.


The Gram stain is part of a family of histochemical special stains that many laboratories around the world still run manually today. In automating the stain, Ventana (VMSI; Tucson, AZ, USA) offers an efficient and automated method to perform this technically challenging assay, enabling them to achieve increased productivity, consistency, and testing quality.

"Tissue diagnostics play a critical role in enabling accurate diagnosis and treatment decisions for cancer patients. Ventana provides laboratories, pathologists, and their patients with novel assays, and the company is empowering its customers to achieve greater efficiencies by automating common, yet labor-intensive tests like the Gram stain," says Mara G. Aspinall, president, Ventana Medical Systems, Inc.

The Gram Staining kit is the newest addition to the Ventana product offerings on the fully automated BenchMark Special Stains platform launched in mid-2012. The kit offers two counterstain options and testing protocol flexibility to meet pathologists' individual preferences.

"The new Gram Staining Kit will provide our customers visual consistency and clarity rarely achieved with manual Gram staining protocols. Our commitment to quality and advancing diagnostic consistency through world-class automation shines with this new product," said Adrian Ralph, vice president, Primary Staining, Ventana Medical Systems, Inc.

The VENTANA Gram Stain Kit is being launched as a US Class I exempt/ CE-IVD product.
