About Quotient

With perspective that can only come from substantial experience, we are focused on delivering tomorrow's diagnostic solutions

At Quotient, we see the future of transfusion medicine through a different lens. One that brings a new level of technology, efficiency and improved outcomes to the entire field.

Who we are: Quotient is a commercial-stage diagnostics company committed to reducing healthcare costs and improving patient care by delivering superior products and innovative solutions. The company's operations are based in Eysins, Switzerland; Edinburgh, Scotland; and Newtown, Pennsylvania.

Our story: we pride ourselves on being a quality, innovative provider of reagents for use in blood transfusion medicine—and we’ve been doing it for over 30 years. Quotient's research & manufacturing subsidiary, formerly traded under the name Alba Bioscience, was originally established in Scotland in the 1940s to manufacture blood typing reagents as part of the Scottish National Blood Transfusion Service. In addition to supplying its products throughout the Scottish National Health System, the company grew and expanded its offerings as an Original Equipment Manufacturer (OEM) supplier to the world’s leading transfusion diagnostics companies. In 2007, it was privatized and became part of what is now Quotient. Leveraging its expertise in transfusion diagnostics, Quotient is developing MosaiQ™, its next generation automation platform to address the comprehensive needs of the global transfusion diagnostics market.

Our strong heritage in transfusion diagnostics gives us a unique perspective, enabling us to bring you the absolute best quality reagents alongside the most cutting-edge technology in the industry.

Our Products and Services

MosaiQ™: Quotient's next-generation automation platform for both blood grouping and donor disease screening, represents a groundbreaking testing platform designed to address current and emerging needs of the $3.4 billion global transfusion diagnostics market. 

Utilizing a single instrument platform, MosaiQ has been designed to offer a breadth of diagnostic tests unmatched by existing commercially available transfusion diagnostic instrument platforms, spanning blood grouping (for donor and patient testing) and serological and molecular disease screening for donor testing.

Once approved, MosaiQ will be the only fully automated solution for blood grouping that provides comprehensive antigen and antibody panels of donor and patient blood, and all mandated serological and molecular disease screening tests for donor blood; within turnaround times significantly quicker than existing methods. Widespread adoption of MosaiQ is expected to offer improved patient outcomes through better and easier matching of donor and patient blood, given cost-effective extended antigen typing offered by MosaiQ.

MosaiQ will also offer the opportunity for substantial cost savings and a range of operational efficiencies for donor and patient testing laboratories.

Quotient expects to develop additional applications for MosaiQ, starting with nucleic acid testing for donor molecular disease screening, upon completion of assay development for the blood grouping and serological disease screening applications.

Reagents: We currently offer a portfolio of products used for blood grouping, as well as whole blood controls used daily for quality assurance testing of third-party blood grouping instruments. We have introduced a range of FDA-licensed products in the United States under the Quotient brand, which we sell directly to donor testing laboratories, hospitals and independent patient testing laboratories.

Original Equipment Manufacturer (OEM): we also develop, manufacture and sell conventional reagent products to original equipment manufacturers, or OEMs including some of the top transfusion diagnostic companies.
