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
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
QC / calibration failure on an assay
HighSymptoms: Controls out of range, calibration fails, flagged results on one or more assays.
Root cause: Reagent pack issue, a probe / dispense fault, incubation-temperature drift, or a detector / optics fault.
Sample / reagent probe or pipettor fault
MediumSymptoms: Short aspiration, no dispense, clot / level-sense errors, carryover.
Root cause: Clogged or bent probe, a syringe / pump fault, or a level-sense fault.
Wash / aspiration station fault
MediumSymptoms: High background / noise, poor precision, elevated blanks.
Root cause: Blocked wash-station nozzles or a wash-pump / vacuum fault.
Incubator temperature fault
MediumSymptoms: Assay drift or bias, incubation-temperature alarm.
Root cause: Incubator heater or temperature-sensor fault.
Detector / luminometer / photometer fault
MediumSymptoms: Low signal, high CV, detector-error message.
Root cause: PMT / detector ageing or an optics fault.

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 starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: QC / calibration failure on an assay
- Run fresh controls at all levels and recalibrate the affected assay.
- Confirm the reagent pack is in date, mixed and correctly loaded.
- Clean the sample / reagent probes and the wash stations.
- Check the incubator temperature against a reference.
- Escalate a detector / luminometer / photometer fault to the OEM.
Symptom: Sample / reagent probe or pipettor fault
- Inspect the probe for a bend or clog and clear it.
- Run the fluidics prime.
- Check the syringe / dispense pump and tubing for leaks or air.
- Verify level sensing and probe position.
- Replace the probe or syringe as found and re-run QC.
Symptom: High background / poor precision / elevated blanks
- Clean or unblock the wash-station nozzles.
- Check the wash pump and vacuum.
- Confirm the substrate / trigger reagents are fresh.
- Run a precision check.
- Escalate an optics / detector fault.

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
