Dear Valued Customer,

At the beginning of May 2018, Prolacta Bioscience® made a minor change to the format of the lot number printed on each product label. The lot number has increased from 9 alphanumeric characters to 11. Shown below is the configuration of the current and new lot numbers:                                                                                 

Lot Number

Number of Alphanumeric Characters








In the example above, the two additional characters in the new number, US, refer to the two-letter ISO country code, in this case, the United States. The last character, A, is not new. 

Implementation of new lot numbers will extend over the next few months. It is expected that the entire product line will feature new lot numbers by the end of July 2018.

We have already communicated this change to the top ten barcode scanning vendors* that serve neonatal intensive care units. Nevertheless, please check with your barcode scanning vendor regarding any software updates that may be required following this change. 

If you have any questions, please feel free to contact us at

Sincerely yours,

Alan Kofsky

Vice President of Sales and Marketing
