- 01GDP / GMPTemperature control under EU GDP: what is expectedEU GDP requires premises that hold storage conditions, mapping before use, calibrated monitoring equipment, alarms, and records that demonstrate control.3 min
- 02GDP / GMPStorage condition labels explained: 2–8 °C, 15–25 °C, 'do not freeze'Label storage conditions come from stability studies, and each phrase has a defined meaning that sets the limits for mapping, monitoring and excursions.3 min
- 03GDP / GMPWarehouse qualification under GDP: from URS to routine monitoringA qualified warehouse has a documented requirement, a mapping study that meets it, monitoring placed by the results, and a trigger for re-qualification.3 min
- 04GDP / GMPQualifying temperature-controlled vehicles and shipping containersTransport equipment is qualified like storage: define the conditions, map with calibrated loggers under worst-case ambient and load, and monitor every shipment.3 min
- 05MonitoringWhat a continuous temperature monitoring system must doCapture at an appropriate interval, alarm reliably, store data securely with an audit trail, and keep working through power and network failures.3 min
- 06MonitoringAlarm limits vs acceptance limits: setting them correctlyAcceptance limits come from the product; alarm limits sit inside them to give time to act, alert limits inside those. Uncertainty and delay set the gaps.3 min
- 07MonitoringReviewing and retaining monitoring recordsA monitoring record nobody reviews is not a control. Define the review frequency, what the reviewer checks, how it is recorded, and how long it is kept.3 min
- 08GDP / GMPHandling temperature excursions in storage and distributionAn excursion is assessed against the product's stability data, not averaged away. Six hours at 12 °C in a 40-day cold-chain profile moves MKT by 0.08 °C.3 min
- 09GDP / GMPMean kinetic temperature (MKT): what it is and when to use itMKT is not an average. It is the single temperature that would do the same cumulative chemical damage, which is why it sits above the arithmetic mean.4 min
- 10GDP / GMPDeviations and CAPA for environmental control failuresAn excursion, a failed calibration or a failed mapping is a deviation. Classify it, investigate the root cause proportionately, and close it with action.3 min
- 11GDP / GMPData integrity for temperature records: ALCOA+ in practiceTemperature records are GxP records. Attributable, legible, contemporaneous, original and accurate — plus complete, consistent, enduring and available.3 min
