Overview
Component storage conditions are the validated temperature and agitation environments required to maintain blood product integrity from receipt through issue.
Classification
| Product | Storage category |
|---|---|
| Packed RBCs / whole blood | Refrigerated, monitored |
| FFP / frozen cryoprecipitate | Frozen, monitored |
| Platelets | Room temperature + agitation |
| Thawed plasma/cryo | Short post-thaw rules per SOP |
Morphologic Features
Not morphologic.
Laboratory Characteristics
- Validated equipment only
- Continuous monitoring and alarm response
- Product-to-device mapping must be correct
Reference Intervals
Exact acceptable temperature ranges and excursion criteria are institutional/regulatory, verify SOP; educational materials should not invent universal cutoffs.
Clinical and Laboratory Significance
Storage integrity is a prerequisite for safe issue; dating alone does not prove correct storage history.
Differential Considerations
Alarm causes include door ajar, equipment failure, power loss, or probe issues, investigate before clearing inventory.
Comparison Tables
| Failure | Typical concern |
|---|---|
| RBC fridge warm excursion | Red-cell integrity / bacterial risk framing per SOP |
| Platelet agitator stopped | Loss of viability / swirl failure |
| Freezer warm excursion | Plasma/cryo integrity |
Classification Frameworks
Not applicable.
Laboratory Notes
- Never store platelets in the RBC refrigerator
- Document alarm investigations
- Quarantine until disposition is complete
