Below we describe two data structures for encoding the manufacturer’s blood pack catalogue and lot numbers. The structures are fundamentally different but both coding systems use two data structures. For Codabar the manufacturer’s code is with the lot number and the catalogue number/pack type is a separate code. For ISBT 128 the catalogue number/pack type is with the manufacturer’s code and the lot number is a separate code. For ISBT both the catalogue and lot number are required to uniquely identify a batch of blood bags.
Currently Blood Services request Codabar barcoded information on each pack. Two classes of data are recorded, namely:
Catalogue number (pack type)
This label defines the type of pack, e.g. whole blood, platelet etc. The code is defined as follows:
cppppppk7b
Where:
| c | is the start code |
| pppppp | is the manufacturer’s list/catalogue number |
| k | is the modulus 11 check digit |
| 7b | is the stop code. |
Batch/lot number
This number describes the batch/lot number for each individual pack. The format is:
b1XXDDDDDDDC6b
Where:
| b1 | is the start code |
| XX | is the manufacturer’s code (see Table 26.2) |
| DDDDDDD | is the batch/lot number |
| C | is a modulus 11 check digit based on XXDDDDDDD |
| 6b | is the stop code. |

To achieve ISBT 128 compliance the UK Blood Transfusion Services will adopt the ISBT 128 convention for manufacturers’ blood pack catalogue and lot numbers. Details are provided in the current version of ISBT 128 Standard Technical Specification, Data Structures 017 and 018, which is available on ICCBBA’s website (www.iccbba.org).
