Служба Крови is the official application of the State program for the development of voluntary blood donation and its components. Users can access functionalities such as donation planning, donation tracking manually or automatically with a 20-digit donation code, information on medical and laboratory test results, contraindications to donation, and donation preparation. Additionally, the app allows donors to enjoy privileges and promotions from project partner companies in their region. To unlock the full functionality, users need to obtain a 20-digit donation code from the blood service institution where the last procedure was performed.

Some institutions may not have the technical capability to provide 20-digit donation codes due to the lack of connection to an automated transfusion information system. Users can check the list of institutions capable of providing donation codes on the portal's "Where to Donate Blood?" section or within the app under the Blood Service Institutions section.
