What This Guide Helps With
Use this guide when sample identification, LIS orders, result transmission, or network communication is unavailable, delayed, or inconsistent.
Step-by-Step Troubleshooting
1. Protect Patient Identification and Result Workflow
Do not allow results to be associated with the wrong patient or released through an unreliable interface.
Determine whether the problem affects:
- Barcode reading
- Worklist or order receipt
- Result transmission
- Bidirectional LIS communication
- One sample or all samples
- Only the Atellica IM 1600 or multiple laboratory systems
Use the laboratory's approved downtime workflow when required.
Expected outcome: Patient identification is protected and the affected portion of the communication path is identified.
2. Separate Barcode Problems From LIS Problems
Test whether the analyzer can:
- Physically read a known-good barcode
- Display the correct sample ID
- Receive an order for that ID
- Process the test
- Transmit the completed result
This prevents treating every identification problem as a network failure.
Expected outcome: The failure is narrowed to barcode acquisition, analyzer/LIS communication, or result transmission.
3. Inspect Sample Barcodes
For barcode-specific problems, inspect the label for:
- Wrinkles
- Smearing
- Damage
- Poor contrast
- Multiple overlapping barcodes
- Incorrect orientation
- Label placement interfering with scanning
If available, compare with a known-good labeled specimen or test identifier.
Expected outcome: The analyzer reads a suitable barcode correctly. If replacing an unreadable label resolves the problem, troubleshooting can stop after verification.
4. Inspect the Barcode Reader Area
Inspect the externally accessible reader window or scanning area for:
- Dust
- Residue
- Condensation
- Obstruction
- Physical damage
Clean only using the approved external method.
Expected outcome: The reader area is clean and unobstructed. If barcode reading returns to normal, the issue is resolved.
5. Verify Physical Network Connections
Inspect accessible network connections associated with the analyzer and connected workstation.
Check for:
- Disconnected cable
- Loose connector
- Damaged cable
- Recently moved equipment
- Missing link indication where normally available
- Known switch or network maintenance
Do not move cables to unknown network ports simply to test connectivity.
Expected outcome: Physical network connectivity is intact. If reseating an approved connection restores communication, proceed to end-to-end verification.
6. Determine Whether the Network Problem Is Local or Broader
Check whether:
- Other analyzers are communicating with the LIS
- The Atellica IM 1600 is the only affected device
- The local workstation can reach its normal interface functions
- IT or laboratory staff report a broader LIS outage
Avoid changing IP, gateway, DNS, interface, or instrument configuration without approved documentation and authorization.
Expected outcome: The problem is categorized as analyzer-specific, interface-specific, or infrastructure-wide.
7. Verify Interface Status Without Changing Configuration
Review normal user-accessible analyzer or interface status indicators.
Document:
- Connected/disconnected state
- Queued results
- Pending orders
- Communication warning
- Time communication stopped
Do not clear queues or manually alter interface configuration unless authorized and the data impact is understood.
Expected outcome: The communication failure is characterized without risking result loss.
8. Test the Complete Communication Path
After any correction, use an approved test specimen or laboratory test workflow to verify:
- Barcode read
- Correct sample identification
- Order receipt
- Test processing
- Correct result transmission
- Result appearance at the intended LIS destination
Expected outcome: The complete barcode-to-LIS path works correctly. Troubleshooting can stop.
9. Escalate Persistent Communication Problems
If barcode hardware, external cabling, and local analyzer status are normal but communication remains unavailable, coordinate with laboratory IT, middleware support, LIS support, network services, or Siemens Healthineers as appropriate.
Expected outcome: The unresolved interface problem is escalated to the correct support group with sufficient troubleshooting information.
If the Problem Persists
If labels, barcode reader condition, external cabling, analyzer interface status, and broader infrastructure status have been checked, common external causes have been ruled out.
Possible remaining categories include internal barcode reader failure, analyzer network interface, middleware or LIS configuration, switch/VLAN infrastructure, server-side communication, or application-level integration.
The affected communication pathway should be:
- Removed from clinical use when patient identification or result integrity cannot be assured
- Labeled Out of Service when the analyzer itself must be removed from use
- Evaluated using approved manufacturer and IT documentation
- Repaired or configured only by qualified Clinical Engineering, IT, LIS, middleware, or manufacturer personnel
Verify the complete order-and-result path before returning normal electronic workflow to service.
Knowing when to stop external troubleshooting is proper troubleshooting.
Clinical Use Tip
A result displayed correctly on the analyzer is not enough; confirm it reaches the correct patient record before declaring an LIS communication issue resolved.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Laboratory staff reported that the Atellica IM 1600 was processing samples but results were not appearing in the LIS."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found the analyzer's external network connection was loose while barcode reading and local processing remained normal."
Resolution
What action was taken.
Example:
"The network connection was securely reseated and an approved test confirmed correct order receipt and result transmission to the LIS."
Helpful Details to Include (If Known)
- Barcode, order, or result-transfer symptom
- Exact communication message
- Whether one or all samples were affected
- Barcode label condition
- Barcode reader condition
- Network cable and link status
- Other analyzers affected
- Known LIS or middleware outage
- Pending or queued result behavior
- End-to-end verification result
- Final analyzer status
Final Thought
Communication troubleshooting should isolate barcode acquisition, physical networking, analyzer interface status, and LIS infrastructure without making uncontrolled configuration changes. The issue is resolved only when the complete patient-identification and result path is verified.
That is successful troubleshooting.
