Cold Chain Refrigerator Mapping for Diagnostic Samples

Anonymized case study

Project background

A diagnostic centre needed evidence of temperature distribution for refrigerators used for sensitive materials.

This representative case study is written for hospitals, diagnostic centres, biomedical engineers and quality teams planning calibration, preventive maintenance, validation, electrical safety testing or audit documentation.

Approach

• Defined mapping locations and study duration.
• Placed calibrated data loggers as per the agreed plan.
• Reviewed temperature variation, hot spots and cold spots.
• Submitted the mapping report with observations.

Outcome

• Cold-chain storage evidence became stronger.
• Temperature risks could be reviewed before audit.
• The centre had better records for storage qualification.

Equipment involved

• Refrigerators
• Data loggers
