Protecting global blood banks

Minimising the risk of bacterial contamination of blood and transfusion materials tops the agenda of medical practitioners involved in this area of healthcare. A new technique could render blood transfusions safer than ever before by eliminating contamination risks.
Protecting global blood banks
An Israeli-based SME has developed a new technology for the rapid detection of bacterial contaminants in transfusion-derived blood platelet units. Platelets are a specific subgroup of blood cells involved in the clotting process. Platelet units are at a particular risk of contamination since they are kept at 22 degrees C for up to 5 days following donation.

This new detection system employs impedance spectroscopy technology and is non-invasive. One of the basic principles behind this system is that growing bacterial cells alter the electrical characteristics of their growth medium. Taking these changes into consideration, has allowed researchers to monitor for such alterations and develop a robust, rapid and effective monitoring system.

This new approach takes less than one minute to perform and overall costs for the procedure are low, given that there are no special requirements for additional reagents and specialised personnel. Laboratory prototypes have been produced and can be used to demonstrate the merits of this innovative technology, patents for which have already been filed.

The company is in a position to negotiate specific terms for licensing deals of varied forms. It invites private sector companies active in the field of medical devices to explore the possibility of up-scaling production efforts to commercial needs and providing further engineering and technical support.
