The Importance of Using Monitored Storage Devices for COVID-19 Test Kits

Storing diagnostic test kits within the correct temperature range is important for ensuring accurate test results. Each test comes with manufacturer’s Instructions for Use (IFU) that defines the storage requirements for the kit. When refrigerated or frozen storage is specified, test kits must be stored within a precise temperature range to ensure the accuracy of test results.

CDC guidance requires that storage temperatures for coronavirus test kits be monitored. To avoid the risks associated with false-negative results for an infected individual, it is critical that laboratory staff be alerted to out-of-range conditions. This can be achieved by using medical-grade storage units with built-in alarm monitoring.

At a minimum, a medical-grade refrigerator should include alarms for high and low temperatures, and for conditions that could adversely affect the temperature, such as leaving the door open or a power failure.

GX Solutions refrigerators and freezers from Helmer Scientific support compliance by monitoring the temperature inside of the storage unit. Alarms are generated if the temperature rises above or falls below the acceptable range. Alarms for power failure and the door being left open for an extended period are also included.

It is also important for the alarms on the refrigerator or freezer to have a built-in battery back-up. This enables the system to emit alarms during a power failure, so users will be alerted when the power has been out long enough to cause a temperature excursion.

Helmer also offers models with advanced alarm and datalogging features. i.Series® units with the i.C3® Information Center provide additional safeguards such as a compressor high temperature alarm, a probe failure alarm, and a low battery alarm. Downloadable temperature data, temperature graphs, and event history reports also help support monitoring compliance.


Helmer Scientific supports clinical laboratories, the patients they serve, and their efforts to ensure accurate test results. We would like to express our gratitude to all staff involved in the diagnostic testing that is critical for treating patients and saving lives. We are here to help you properly store your critical materials during the COVID-19 pandemic.
