Abaxis Vetscan HM2
Abaxis · Model Vetscan HM2
Small sample size requirement: consumes approximately25 µl of EDTA-preserved whole blood per CBC measurement. Rapid test turnaround: only 2–3 minutes to results. Advanced, integrated self-cleaning system for optimized performance with very minimal maintenance - expanded automatic aperture cleaning after every run. Simple, intuitive, and easy-to-use software interface makes the analyzer very user friendly, and requires only a short learning curve. Accurate results for out-of-range values: automatic calculations are provided for external 1:5 dilutions in cases of extremely high values or very small sample volumes. Simple, flexible database with large storage capacity: Automatically saves up to 1,000 test records. Data can be downloaded to a USB flash drive or a compatible data-management system. Quality control (QC) results (including Levy-Jennings charts) are stored in the instrument’s QC database for viewing and management. User reminders for replacing the reagent pack and performing simple maintenance task Integrated laboratory results: the HM2 canbe connected to a VetScan Chemistry Analyzer for integrated results reporting. Advanced user features: Multi user mode, customizable normal range, and adjustable analizing strength.
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.
Aperture blockage / clog
HighSymptoms: Flagged or implausible CBC counts, clog alarm, poor precision.
Root cause: Debris or a clot partially blocking the counting aperture.
Reagent / lyse delivery fault
MediumSymptoms: WBC or HGB results shifted, high background, reagent-empty or pressure alarms.
Root cause: Reagent pack depleted or expired, or a tubing / pinch-valve fault.
Sample probe / aspiration fault
MediumSymptoms: Short samples, no aspiration, probe-position errors.
Root cause: Worn or bent sample probe, or a clot in the sample.
HGB photometer drift
MediumSymptoms: Haemoglobin results biased, blank absorbance off.
Root cause: Photometer lamp aging or a dirty flow cell.

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: Clog alarm / flagged counts
- Run the instrument's aperture-clear / flush cycle.
- Run a background count and confirm it is within limits.
- Run controls at all levels.
- Clean or replace the aperture assembly if clogs recur.
- Confirm precision on a replicate sample.
Symptom: Short samples / aspiration errors
- Inspect the sample probe for a bend or blockage.
- Check the tubing and pinch valves for leaks or collapse.
- Verify the sample is not clotted.
- Replace the probe or tubing as found.
- Re-run controls.
