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.

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.
Symptom: Reagent / wash flow fault
- Confirm the presentation - typically clogs, high blank, QC fail - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: pump tube wear, air in line.
- 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 peristaltic pump tubing 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
Invalid calibrations (out of range high) while using the product.
- RECALL
bioMerieux has been receiving an increasing number of complaints linked to a VIDAS substrate error. It prevents the test from being run, therefore leads to potential delayed results as the user must run another test.
- RECALL
bioMerieux received complaints about calibration issue observed on several lots of VIDAS CMV IgM (ref 30205 ; 30205-01).
- RECALL
Two batches of VIDAS Varicella-Zoster IgG (VZG ref 30217) may yield an invalid calibration which may delay the patient's sample result or a valid calibration may lead to a false positive patient result.
- RECALL
Following Customers complaints, investigations have been initiated on potentially false results obtained on VIDAS 3 with an expired calibration. Indeed, the calibrations of assays were valid in the calibration menu whereas in fact the calibrations were expired and no alarm displayed to warn the users about the expiration date of the calibrations. Software computes results of analysis for assays with expired calibrations. The anomaly is due to an incorrect update of the calibration status by the software.
- RECALL
Invalid calibration with low calibrator S1 while using the product.
- RECALL
Several complaints were received for invalid calibration with low calibrator S1 while using VIDAS LH. Internal tests confirmed a decrease of the strips signal overtime for specific lots.
- RECALL
Complaints were received from customers observing falsely overestimate results or external quality control higher results than expected when performing tests with VIDAS Testosterone.
- RECALL
Fulvestrant cross reacts with the VIDAS Estradiol II immunoassay and may cause falsely elevated estradiol results in patients treated with Fulvestrant.
- RECALL
During development of the VIDAS 3 software version 1.2, some anomalies have been identified and observed to be already present in the current software version VIDAS 3 version 1.1.4. available in the field.
- RECALL
Due to a packaging error; The kit does not contain the correct number of C1 or C2 control vials.
- RECALL
Product is not approved or authorized for distribution in the US.
- RECALL
Customer complaints about not repeatable results below the detection limit (<45 ng/mL). Therefore false negatives are being reported for results around the medical decision point of 500 ng/mL that initially tested at <45 ng/mL.
- RECALL
Complaints were received of high rates of false positive results, leading to unnecessary antibiotic therapy being prescribed to patients.
- RECALL
The product may give false positive results.
- RECALL
Kit may contain incorrect components
- RECALL
Product's decrease in sensitivity may result in false negative results
