Loss of visibility
There is no unified view of where the sample is or who received it.
END-TO-END BIOLOGICAL SAMPLE TRACEABILITY
Every sample.
One identity.
Complete traceability.
BioSampleTrace creates a controlled digital chain between the hospital and external laboratory, from registration and labeling through dispatch, processing and secure return of results.

THE TRACEABILITY GAP
The sample moves physically.
Its information must follow it.
When transfers between hospitals and external laboratories rely on paper, telephone calls and disconnected systems, the actual status of a sample cannot be readily verified.
Disconnected handovers
Dispatch lists, laboratories and results function as separate processes.
Delays
A delay is identified only when someone searches for a sample or result.
Incomplete audit trail
Establishing who did what and when requires manual investigation.
BIOSAMPLETRACE PLATFORM
The physical journey becomes a digital chain of custody.
Each sample receives a unique code and follows controlled status transitions. The physical sample stays connected to the proper workflow without sending patient identifiers to the external environment.
- Server-generated unique Sample Code
- Barcode / QR labeling and printing
- Dispatch lists and receipt confirmation
- Role-scoped access and audit history
- Controlled return of results

UNIQUE SAMPLE CODEBST-26-08F4A91C
SAMPLE LIFECYCLE
From registration to result.
Every transition is recorded.
Registration
Register the examination and create a Sample Code.
Label
Connect barcode / QR to the physical sample.
Dispatch
Dispatch list and controlled shipment.
Lab Received
Confirm physical receipt.
Processing
Update operational status.
Result
Secure return of results.
Exception handlingRejected sample→Mandatory reason→Audit event→Hospital notification
PRIVACY BY ARCHITECTURE
Patient information remains within the hospital environment.
The external workflow relies on the operational identity of the sample, not the patient's identity.
TRUST ZONE A
Hospital Environment
Identifiers and clinical information remain in the internal system.

The laboratory uses a coded sample identity.

EXTERNAL LABORATORY PORTAL
The laboratory sees only what it needs to process.
The laboratory queue contains only samples actually dispatched to it. Creating an examination in the hospital does not constitute dispatch.
- Confirm physical receipt
- Status by Sample Code
- Reject with a reason
- Controlled delivery of results
SECURE RESULT DELIVERY
The result returns to where it belongs.
Results follow a controlled path back to the hospital and become available to authorized users in the internal environment.
