Checksum Algorithm
Beckman Coulter strongly recommends the use of bar-code checksums to provide automatic
checks for read accuracy.
The algorithm for determining the checksum for each code is as follows:
Interleaved 2-of-5
This code requires 3 to 15 data digits plus a checksum or 16 digits without checksum. The
number of printed characters must always be even in length. Therefore, printers will
automatically add a leading zero as a filler if an odd number of characters is chosen.
To determine the value of the checksum character:
1.
Identify even- and odd-positioned characters in the message with the right-hand message
character
always
defined as an even-positioned character.
2.
Sum the numeric values of the odd-positioned characters.
3.
Sum the numeric values of the even-positioned characters and multiply the total by 3.
4.
Sum the odd and even totals from steps 2 and 3.
5.
Determine the smallest number which, when added to the sum in step 4, results in a
multiple of 10.

Although the LH 700 Series analyzer with SlideMaker accepts up to 16-character bar codes, the SlideMaker only prints the human-readable
information on the slide for bar-code labels with 12 or more digits.
IMPORTANT
Use of bar codes is an extremely accurate and effective method of positive patient
identification. Certain features, such as checksum digits, maximize accuracy in reading Codabar, Code 39
and Interleaved 2-of-5 labels. Use checksums to provide protection against occasional misread errors
caused by problems such as damaged or misapplied labels. If you must use bar-codes without
checksums, Beckman Coulter recommends that you verify each bar-code reading to assure correct patient
identification.
