Laboratory Material Quarantine
Laboratory material quarantine is a controlled process used to temporarily segregate materials when their identity, condition, quality, documentation, storage history or suitability has not yet been established. Quarantine helps prevent materials that require review from being inadvertently used, released, transferred or mixed with approved laboratory inventory.
What Is Laboratory Material Quarantine?
Laboratory material quarantine is the controlled segregation of laboratory materials that are awaiting inspection, verification, testing, investigation or an appropriate disposition decision.
Quarantined materials should be clearly identified and physically or procedurally controlled so that they are not unintentionally treated as approved or available materials. The exact quarantine requirements depend on the laboratory's quality system, material type and applicable procedures.
What Is Laboratory Material Quarantine?
Quarantine is a temporary status assigned to material when it should not yet be considered approved or available for routine use.
The status may apply to newly received laboratory materials, materials awaiting quality review, materials associated with a documentation discrepancy or materials involved in an investigation.
The purpose is not necessarily to indicate that the material is defective. Instead, quarantine provides a controlled status while an appropriate evaluation or decision is pending.
Why Is Laboratory Material Quarantine Important?
Laboratories may receive or encounter materials whose status cannot immediately be confirmed. Allowing such materials to enter routine inventory without appropriate review can create traceability, quality or workflow risks.
Quarantine provides a controlled intermediate status between receipt or identification and final disposition.
| Quarantine Objective | Purpose |
|---|---|
| Prevent unintended use | Helps prevent material awaiting review from being used before its status is established. |
| Maintain segregation | Keeps unresolved materials separate from approved inventory. |
| Preserve traceability | Maintains the connection between material and relevant records. |
| Support investigation | Provides controlled status while discrepancies or quality concerns are evaluated. |
| Document disposition | Creates a record of the final decision regarding the material. |
Common Reasons for Laboratory Material Quarantine
There are several situations in which laboratory materials may appropriately require a temporary quarantine status.
Newly Received Materials
Materials may remain in quarantine while receiving checks, documentation review or other required verification activities are completed.
Identification Discrepancies
A material may require quarantine if its label, lot number, batch information or accompanying documentation does not match expected records.
Damaged Packaging
Materials associated with damaged containers, closures or packaging may require evaluation before their status is determined.
Unexpected Appearance
An unexpected change in appearance may warrant review according to the laboratory's applicable procedures.
Storage Excursions
Materials exposed to conditions outside their specified storage requirements may require evaluation before being released for routine use.
Documentation Issues
Missing, incomplete or inconsistent documentation can prevent a material from being appropriately released until the issue is resolved.
Quality Investigation
Materials associated with an ongoing investigation may be quarantined to prevent further use or movement until an appropriate decision is reached.
Quarantine Identification and Labeling
Clear identification is essential to effective quarantine management. Personnel should be able to distinguish quarantined materials from approved laboratory inventory.
Quarantine identification may be provided through labels, designated locations, inventory-system status indicators or a combination of physical and electronic controls.
| Information | Purpose |
|---|---|
| Material or sample name | Identifies the material under quarantine. |
| Lot or batch number | Supports traceability to the relevant production or supply lot. |
| Quarantine status | Clearly communicates that the material is not currently approved for routine use. |
| Date placed in quarantine | Provides a reference point for the quarantine event. |
| Reason for quarantine | Explains why the material requires review when appropriate. |
| Relevant reference number | May connect the material to an investigation, deviation or quality record. |

Physical and Procedural Segregation
Quarantine is most effective when the status of the material is difficult to misunderstand.
Depending on the laboratory environment, segregation may involve a dedicated quarantine storage area, clearly marked containers, electronic inventory controls or restricted access.
Physical Segregation
A designated quarantine area can reduce the possibility of quarantined materials being mistaken for approved inventory.
Electronic Segregation
Inventory systems may use a status field to identify materials that are awaiting review or disposition.
Access Controls
Where appropriate, access to quarantined materials can be restricted to authorized personnel.
Clear Status Communication
Personnel should be able to determine the material's status without relying on assumptions or memory.
Physical + Electronic Controls
For laboratories using electronic inventory systems, physical segregation and electronic status controls can complement one another. A mismatch between the physical location and inventory status should be investigated according to applicable procedures.
Storage of Quarantined Laboratory Materials
Quarantine does not eliminate the need to maintain appropriate storage conditions. Materials should continue to be stored according to their applicable requirements unless a documented procedure specifies otherwise.
Storage locations should protect the material while also making its quarantine status clear.
| Storage Consideration | Why It Matters |
|---|---|
| Temperature | Materials may still require specified temperature conditions while awaiting review. |
| Light exposure | Materials with light-sensitive requirements may need appropriate protection. |
| Container integrity | Vials and containers should remain protected from avoidable damage. |
| Segregation | Quarantined material should remain distinguishable from approved inventory. |
| Traceability | Storage location should remain connected to relevant inventory or laboratory records. |
Related storage practices are discussed in Laboratory Storage Logs.
Laboratory Material Quarantine Documentation
Documentation provides a record of why material entered quarantine, what actions were performed and how the final disposition was determined.
The exact records depend on the laboratory's quality system and the nature of the material.
Useful Quarantine Record Elements
- Material or sample identification
- Lot or batch number
- Date of quarantine
- Reason for quarantine
- Storage location
- Relevant inspection or review information
- Associated investigation or deviation reference, when applicable
- Final disposition
- Date of disposition
- Authorization or review information where required
Good documentation practices help establish a clear history from the initial quarantine event through final disposition.
Evaluation of Quarantined Materials
The evaluation required before release depends on why the material was quarantined.
For example, a documentation discrepancy may require record verification, while an unexpected physical condition may require inspection or additional quality assessment.
| Quarantine Reason | Potential Review Area |
|---|---|
| Documentation discrepancy | Review relevant certificates, records, labels and inventory information. |
| Damaged packaging | Assess container and packaging condition according to applicable procedures. |
| Unexpected appearance | Perform appropriate inspection or testing where required. |
| Storage excursion | Review the event and applicable material requirements. |
| Quality investigation | Follow the applicable investigation and disposition procedure. |
Laboratory Material Quarantine Disposition
Once the required review has been completed, the material should receive an appropriate documented disposition.
Released
If the applicable requirements are satisfied, the material may be released from quarantine according to the laboratory's procedures.
Rejected
Material that does not meet applicable requirements may be rejected or otherwise controlled according to the laboratory's procedures.
Returned
Where appropriate, material may be returned to the supplier or originating facility according to established procedures.
Further Investigation
If available information is insufficient to make a final decision, the material may remain under controlled status while additional investigation takes place.
| Disposition | General Meaning |
|---|---|
| Released | Material is approved for the applicable laboratory use. |
| Rejected | Material is not approved for the intended use under the applicable criteria. |
| Returned | Material is sent back according to an established process. |
| Continued Quarantine | Additional information, review or investigation remains necessary. |
Quarantine and Laboratory Inventory Management
Quarantine status should remain synchronized with laboratory inventory records where electronic or documented inventory systems are used.
A material should not appear as freely available inventory while it remains under quarantine.
When its status changes, the inventory record should be updated according to the laboratory's procedures so that the physical and documented status remain consistent.
Lot-level inventory practices can provide additional traceability. See Laboratory Inventory Management by Lot and Batch.
Quarantine and Laboratory Receiving
Quarantine is often relevant during the receiving process because newly received materials may require inspection or documentation review before they are introduced into routine inventory.
Receiving personnel may verify information such as material identity, quantity, lot number, packaging condition and accompanying documentation according to established procedures.
See Receiving Laboratory Materials for related receiving controls.
Quarantine and Material Traceability
Traceability allows a laboratory to connect the physical material with its associated records.
For quarantined materials, traceability can be particularly important because the material may be subject to additional inspections, investigations or decisions before release.
Lot numbers, sample identifiers, storage locations and relevant documentation should remain consistent throughout the quarantine process.
Common Laboratory Material Quarantine Mistakes
Unclear Quarantine Labels
If quarantine status is difficult to recognize, personnel may mistakenly treat the material as approved inventory.
Mixing Quarantined and Approved Materials
Poor physical organization can make it difficult to distinguish between materials with different status levels.
Missing Quarantine Records
Without adequate documentation, it may be difficult to determine why material was quarantined or what happened afterward.
Using Quarantined Materials Without Authorization
Material should not be treated as available for routine use while its status remains unresolved unless an applicable procedure specifically permits controlled use.
Failing to Maintain Storage Conditions
Quarantine does not automatically remove the need for appropriate storage conditions.
Not Updating Inventory Status
A physical material may be released or rejected while its electronic or written inventory record still shows an outdated status.
Leaving Materials in Quarantine Indefinitely
Unresolved quarantine status should be reviewed according to the laboratory's procedures so that materials do not remain without an appropriate disposition.
