Blood transfusion plays a critical role in managing patients’ wellbeing within healthcare systems worldwide.
In most parts of the world, there is a wide gap between the demand and supply of safe blood: in 2022, the clinical demand for India was estimated at 14·6 million whole blood units — an equivalent of 36.3 donations per 1,000 eligible populations, which will address whole blood and component requirement. The supply was 93% which is equivalent to 33.8 donations against the demand.
A crucial step in ensuring blood product safety is the screening of donated blood: the WHO recommends that all blood donations be screened for evidence of infection (HIV, hepatitis B and C, and syphilis) before the blood and its components are released for clinical use. Screening donated blood for transfusion-transmissible infections therefore remains a core component of every national blood program.
Faster. Accurate. Compact.
As efforts to boost voluntary blood donation shape supply to bridge this gap, blood and plasma screening centers must be able to keep up with the demand to test higher volumes of blood. This calls for new age technology that can quickly adapt to daily as well as long-term changes, with high quality and consistent delivery of results.
Advanced technologies for screening infectious diseases, like Abbott’s Alinity i System, are refining the blood screening process to elevate the efficiency and productivity of blood banks, reduce the risk of transfusion-transmitted infections, and let more people benefit from blood transfusion.
A compact, scalable solution designed to run complex processes more efficiently, the Alinity i System maintains high accuracy to quality standards of blood and plasma screening. As we equip ourselves with advanced technology, the Alinity i Systems offer a broad menu of tests for laboratories to manage multiple testing needs in one system. Here is how it takes testing to the next level:
Capability for donor selective screening by identifying and deferring high-risk donors
This next-generation technology utilizes high quality assays for blood and plasma screening, delivering a throughput of up to 200 tests per hour. Its simple, intuitive user interface improves user experience and makes it easier to operate.
Making technology accessible for streamlined diagnostic testing
The Alinity i System is built to reduce the amount of manual labour needed to run tests. With 47 onboard reagent positions, this system can support remote labs with fewer operators as well. It, thus, maximizes the efficiency of laboratories, empowering high-performing screening centers to run at their best, today and in the future.
Accuracy with speed
The Alinity i System’s innovation has the potential to create a deep impact on the nation’s blood supply systems, helping governing bodies standardize screening protocols and ensure a steady supply of safe blood and blood products.
Wheels of Change: The Hub and Spoke for Centralizing Blood Transfusion Services
With a network of 4,263 licensed blood banks, the blood transfusion service in India remains fragmented. The public, private, and not-for-profit sectors collectively collect around 12 million units of blood annually.
To address this issue, the policy of the government advocates for a Hub and Spoke approach towards blood transfusion services, wherein blood is collected and processed in the hubs, which are high volume blood banks and distributed through spokes, which are smaller blood banks and blood storage centers in the periphery. An initiative of this depth will require standardization of Transfusion Transmitted Infection (TTI) testing in India— the World Health Organization (WHO) recommends that national blood systems should have uniform implementation of standards and consistency in the quality and safety of blood and blood products.
Advanced molecular screening technologies like the Alinity i System promise to play a pivotal role in implementing these robust initiatives on a national scale. They can screen regular, repeat, non-remunerated voluntary blood donors, and introduce hemovigilance— a look-back system to track donors and keep a check on transfusion-related health reactions.
An adequate supply of blood is essential to keep the pulse of a nation thriving. Sophisticated diagnostic tools like the Alinity i System are ushering in a new era in blood safety, steering us towards a future where sufficient, safe blood is available to every person who needs it, when they need it.
