[CLOSED] Unleashing the Potential of ISBT 128 Chain of Identity Identifier

Updated: Dec 6, 2023

Dive into the Future of Cell Therapy Implementation: Explore the ISBT 128 CoI Identifier with IG-050 During the Public Comment Period

A significant amount of collaboration went into the development of the ISBT 128 Chain of Identity (CoI) Identifier. The resulting standard, ISBT 128 Standard Chain of Identity Identifier (ST-028) was published in December 2022.

Since that time, many ISBT-registered software vendors have incorporated the ISBT 128 CoI Identifier into their systems, and the use of the identifier is now live at multiple sites. These sites use the CoI Identifier to link multiple collections and other critical information associated with a patient-specific, given therapy. To assist sites that are planning their implementation, an implementation guide Implementation Guide: Using the ISBT 128 Chain of Identity Identifier (IG-050) has been drafted and is now available for public comment.

How Can You Help?

Help ensure that this globally unique identifier is implemented to provide bidirectional traceability for complex personalized cell therapy that results in the right cells being administered to the right patient, every time. Don’t miss your opportunity to contribute to the implementation guide!

The deadline for the draft IG-050 comment period has been extended until December 4th, 2023. We've been informed by some attentive commenters that their comment emails bounced. The email issue has been identified and fixed. If you've submitted comments on draft IG-050 and haven't received an acknowledgment, please resend them to We appreciate and value your input and apologize for any inconvenience. If you haven't submitted comments yet, kindly do so before December 4th.

ICCBBA is the international standards organization responsible for the management and development of the ISBT 128 Standard.

The acronym ISBT was originally derived from the important role played by the International Society of Blood Transfusion in the development of the Standard. Today it expands as Information Standard for Blood and Transplantation. The number 128 reflects the 128 characters of the ISO/IEC 646 7-bit character set.

The acronym ICCBBA is derived from the International Council for Commonality in Blood Banking Automation.
