Central Manchester University Hospitals

"The Greater Manchester Immunology Service (GMIS) has been fully reliant on the Kelsius temperature monitoring system for the last 8 years. The system replaced a manual system of temperature recording which was time consuming and inadequate for our requirements. GMIS was the first pathology laboratory in the UK to achieve accreditation to ISO standard 15189 of UKAS. Use of the Kelsius temperature monitoring system strengthened our position and ability to successfully achieve this quality standard. The Kelsius system provides a means of monitoring a bank of fridges, freezers and incubators continually in real time via a system of wireless temperature sensors that upload temperature readings to a central data logger. In the event of a temperature deviation from our defined limits the laboratory personnel are notified immediately and are able to address and rectify any issues. During the last 8 years of use the system has proved very reliable and robust and has not broken down once. The temperature readings are easily accessible from a central web portal that allows the data to be displayed in the form of tables and graphs, providing a full audit trail that is compliant with UKAS. The Kelsius system ultimately contributes to the high quality of our service and patient safety. In addition the ability of the system to continually monitor our temperature readings helps save staff time and allows staff to concentrate on more appropriate duties. Consequently the Kelsius system helps financially by ensuring that expensive commercial kits and reagents aren’t lost due to temperature damage and staff time is used more productively in delivering our immunology service."

BloodScience FAQ

Blood Science's Temperature Monitoring FAQ's

What Is Temperature Monitoring in a Blood Bank Refrigerator?

Temperature monitoring in blood bank refrigerators involves the continuous tracking and recording of internal conditions to ensure blood products remain within safe, regulated temperature ranges.

Using Kelsius’ CoolCheck wireless monitoring system, temperatures are automatically recorded every five minutes. If readings move outside predefined limits, instant alerts are triggered to designated staff. This ensures product viability, regulatory compliance, and prevents costly blood spoilage.

What Is the Recommended Temperature and Humidity for a Blood Bank?

Blood science's must maintain strict environmental conditions to preserve blood product integrity. The recommended temperature range for blood storage refrigerators is between 1°C and 6°C.

While specific humidity levels vary by product type, it’s essential to avoid excessive dryness or condensation, which can damage equipment and compromise storage conditions. With Kelsius’ CoolCheck system, both temperature and humidity are continuously monitored, ensuring compliance with MHRA, HPRA, and FDA standards, while safeguarding blood product quality.

What Is the Maximum Acceptable Temperature for a Blood Bank?

The maximum acceptable temperature for storing blood in a blood bank is 6°C. To maintain safety and efficacy, blood products must be stored between 1°C and 6°C at all times.

Exceeding this range can compromise product quality and render blood unsuitable for transfusion. With Kelsius’ CoolCheck system, continuous monitoring and real-time alerts help ensure temperatures remain within this critical range — protecting patient safety and ensuring full regulatory compliance.

How Do I Monitor My Blood Bank Temperature?

To effectively monitor blood bank temperatures, you need a specialist monitoring system designed to track and maintain storage conditions within the strict range of 1°C to 6°C.

Kelsius’ CoolCheck system uses wireless sensors installed inside blood refrigerators, plasma freezers, and cryogenic units. These sensors automatically record temperature every five minutes and transmit the data to a secure, cloud-based Web Portal. If conditions deviate, instant alerts are sent via the Kelsius App, SMS, email, or voice call.

All data is securely stored for audit readiness and compliance with MHRA, HPRA, FDA 21 CFR Part 11, and blood storage regulations.

Where Should Temperature Sensors Be Placed in a Blood Bank Refrigerator?

For accurate temperature monitoring, sensors should be positioned centrally within the blood bank refrigerator — ideally placed among stored blood products. This provides the most reliable reading of the actual storage conditions.

Avoid placing sensors near doors, vents, or interior walls to minimise false readings. Kelsius’ CoolCheck ensures accurate, reliable monitoring aligned with blood storage standards.

How Do You Control the Temperature of a Blood Bank?

Controlling temperature in a blood bank involves using specialist medical-grade refrigeration systems designed to maintain a consistent range of 1°C to 6°C. These units are equipped with built-in temperature regulation and are supported by digital monitoring systems to ensure safe storage of blood products.

With Kelsius’ CoolCheck system, temperature is monitored automatically every five minutes using wireless sensors. The system provides real-time visibility, automated alerts, and a secure Web Portal for remote access and full audit traceability.

What Are the Different Types of Refrigerators in Blood Banks?

Blood banks rely on a range of specialised refrigeration units to ensure the safe storage and integrity of various blood components. Each type serves a specific purpose and must be precisely monitored to meet regulatory standards.

Blood Bank Refrigerators

Designed for storing whole blood and red blood cells at 1°C to 6°C, these units include advanced temperature control, alarms, and are ideally monitored with Kelsius’ CoolCheck sensors for full compliance and traceability.

Plasma Freezers

Used to store plasma and cryoprecipitate at -18°C or lower, these freezers require robust insulation and constant temperature logging to maintain the frozen state and product efficacy.

Platelet Incubators

Platelets must be stored at 20°C to 24°C with continuous agitation. These incubators are often paired with platelet agitators to prevent clumping and maintain product quality.

Ultra-Low Temperature Freezers (ULT)

For long-term storage, ULT freezers can maintain temperatures down to -80°C, essential for preserving certain blood components over extended periods.

Quarantine Refrigerators

Used to store blood products pending test results or clearance, these units keep quarantined inventory separate from approved stock — often requiring independent monitoring for compliance.

With Kelsius’ wireless temperature monitoring system, all these units can be monitored from a single central dashboard, ensuring real-time visibility, instant alerts, and audit-ready records across your entire blood bank operation.

What Is the Difference Between Blood Bank Refrigerators and Domestic Refrigerators?

Blood bank refrigerators are purpose-built for the safe and compliant storage of blood products, while domestic refrigerators are designed for general household use.

Key Differences:

Precision Control: Blood bank units maintain a strict temperature range of 1°C to 6°C, essential for preserving blood viability. Domestic fridges are less precise and subject to fluctuations.

Continuous Monitoring: Blood bank refrigerators integrate with systems like Kelsius’ CoolCheck, offering real-time monitoring, alarms, and automated alerts. Domestic models lack these capabilities.
