RedLink BD, presented as BloodLab, is a blood donor discovery and community platform designed to help people find potential donors quickly. Users can search by blood group, district, and local area, with listings covering all eight blood types across locations in Bangladesh. The site displays donor profiles and donation counts, alongside popular blood-group searches and featured and latest donor lists. People can also register as donors or submit a request for blood, while login and app-download options support access to the service.

The platform describes its approach as secure, free, and automated, and highlights a community of volunteers and donors. It also provides information about the blood donation process, outlining four stages: registration, health history, donation, and refreshment and recovery. RedLink BD’s stated mission includes promoting safety, increasing blood availability, and encouraging innovation. By bringing donor information and blood requests together, the service aims to make it easier for people seeking blood to connect with volunteer donors in their area.
