Haemonetics TEG Analyzer
Haemonetics · Model TEG Analyzer
Hematology Analyzer The TEG system is comprised of an analyzer and analytic software which together provide a complete picture of the formation and dissolution of blood clots.
Key tips
- ·Run QC controls before trusting any repair - an analyzer that passes self-test can still report clinically wrong results.
- ·Rule out a reagent lot change before opening the instrument - it can look exactly like a hardware fault.
- ·Centrifuge rotors have a hard retirement age/cycle limit regardless of visible condition - don't eyeball it.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Sample probe / pipette clog
MediumSymptoms: Aspiration error, short sample, carryover.
Root cause: Clot/crystal obstruction.
Centrifuge imbalance / bearing
HighSymptoms: Vibration, loud noise, stop error.
Root cause: Worn bearing or unbalanced rotor.
Reagent / wash flow fault
MediumSymptoms: Clogs, high blank, QC fail.
Root cause: Pump tube wear, air in line.
Optics / lamp degradation
LowSymptoms: Low signal, wavelength drift.
Root cause: Lamp/LED or monochromator aging.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily QC controls run and reviewed
- ·Calibration verification per assay
- ·Routine cleaning and decontamination
- ·Scheduled reagent-path and pump-tubing maintenance
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Sample probe / pipette clog
- Confirm the presentation - typically aspiration error, short sample, carryover - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: clot/crystal obstruction.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the sample aspiration probe per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Due to a shift in the citrated blood reference range for a normal population, the ranges stated in the IFU are changing. If the clinician relies solely on affected results in comparison to the normal donor reference range, it could lead to misdiagnosis and incorrect treatment or failure to treat.
- RECALL
When the TEG 5000 Analyzer including TEG Analytical Software is used with PlateletMapping (ADP or AA) Assays and TEG Mangement Software, incorrect values of the PlateletMapping ADP or AA % Inhibition and % Aggretagion may be displayed on TEG Manager for the affected assays.
- RECALL
Software defect in TEG Manager impacts the displayed alert for out of range test results. Due to this defect, reference range values received from TEG 5000 and displayed on the TEG Manager test result screen are rounded to the nearest whole number and lead to TEG Manager displaying an out of range alert when the test result is actually in range, or vice versa.
- RECALL
Specific lots of Level II Control Kits produce high Maximum Amplitude (MA) results, which are outside of the manufacturer's expected Quality Control range for MA parameter.
- RECALL
Research Use Only (RUO) parameters were included in TEG 5000 User Manual.
