Cooler Validation: Comparison of “Manual” Thermometer vs. “Automated” Data Logger Methods

In our March 2012 survey of over 70 blood banks, many respondents generally described cooler validation as a “pain,” characterizing it as time-consuming, frustrating and even primitive.

Most blood banks revalidate their transport coolers annually. And although it is only once a year, there never seems to be a good time or resource-efficient way to do it.


Using multiple data loggers allows more accurate temperature mapping of the cooler interior.

The three key factors we hear repeated most often are:
1. Time Efficiency (technician’s time)
2. Data Accuracy
3. Simplifying Documentation

At the SCABB/CBBS meeting last month, we entertained compelling discussions with blood bankers who have switched from manual cooler validations with thermometers, to using data loggers (electronic temperature recorders). Some of them are using the Val-A-SureTM Cooler Validation Kit.

If you’ve ever considered switching to an automated validation process, we thought it might be helpful to share what we’ve learned from blood bankers across the country. In the following table (next page) we compare the traditional “manual” thermometer method to the “automated” data logger method – and capture how it has changed their validation experiences.

This graph displays temperature of the top bag vs. the bottom bag. The data is downloaded from data loggers and printed for permanent validation documentation, eliminating handwritten and transcribed data.

We’ll be giving away a Val-A-Sure Cooler Validation Kit at AABB 2015, so if you’re interested in a “free” chance to change your cooler validation method, be sure to stop by and see us!

Val-A-Sure Cooler Validation Kit Overview & Introduction

The Val-A-Sure™ Cooler Validation Kit from William Labs (williamlabs.com) combines everything you need in one simple kit for temperature validation of blood transport coolers. All of the necessary components, instructions and documentation for validation are conveniently included in the kit, and have been tested to work together efficiently and accurately.Hands-on trials and feedback from blood banks and laboratories provided the guidance for the Val-A-Sure™ kit development. It delivers the simplicity, accuracy, standardization and speed of process that blood banks and labs told us that they need — in one integrated kit.

Recommended SOPs, temperature recorders and software provide options for an accurate validation process, regardless of your blood bank size. Using electronic recording equipment and following the SOPs, and using the supporting documentation, helps ensure consistent measurement and recording for each validation.

The DVD and documentation supplied with the kit contain:

– QuickStart Guide
– Easy-to-follow 3 minute video instructions of 3 different recommended validation procedures
– Validation SOPs (4 included)
– Validation Log Sheet
– Cooler Label format/template
– Validation Tips
