ISO7064-standardised Check Digits Applied to Blood Bag Numbers
|
Blood product bag numbers |
When composing a EUROCODE-IBLS[5]-compliant blood bag number (lot identifier according to German drug regulations[1,2]) the 9-digit1 BDS-controlled2 serial blood produkt bag number of German blood donation services is prefixed with the 3-digit ISO 3166[6] country code and the 3-digit national arranged center code[5]. The check digit is calculated for the concatenated string and attached as terminating digit.
This concatenation, including check digit, is the blood produkt number relevant as lot identifier after delivery as haemotherpeutical drug.
Example:
blood produkt identifier ("Chargenbezeichnung" according to German drug regulations, "UBN" according to Eurocode-IBLS) | |||||||||

3-digit country code | 3-digit center code | 9-digit center-controlled produkt serial number |
|||||||
276 | 616 | 973212561 | 5 | ||||||
The check digit may never be cut. It is obligatory at any step of lot documentation to remain it concatenated within blood bag numbers even in machine-readable records (such as barcode, OCR type font, and any type of storage media used in information technology).
(1) EUROCODE-IBLS[5] provides from 5 to 11 digit unique BDS-controlled blood product bag serial numbers2. This number may include flags for different secondary products from the same donation or serial split numbers of pooled products.
(2) "Unique BDS-controlled blood product bag serial number" means the unique identification number assigned to the blood product bag by the blood donation service (BDS) under its own responsibility. If the BDS applies proprietary check digits during preparation process, this check digit may be cut to meet national or international Eurocode-complient data structures (e.g. German 9-digit BDS-controlled serial numbers). It is not suitable to proofread BDS-specific check digits at the customers site.
