VetScan VSC Support


If I inadvertently run an expired rotor, do I risk ‘inaccurate results’?

No. The analyser has a built-in sensor to determine the rotor expiration date. The analyser will cancel the run and display an error message.


What is the shelf life of the rotors?

The shelf life for rotors varies depending on the type of rotor. Average shelf life is approximately 9 – 12 months from the date of manufacture. To ensure optimal performance through the expiration date, Abaxis UK recommends that the rotors be refrigerated at 2 – 8 ° C and used one at a time directly from the refrigerator.


If a rotor was exposed to heat do I risk unreliable results as with other systems? Or if run too cold?

All efforts should be made to store rotors at the appropriate storage conditions in order to ensure accurate results. Rotors may tolerate brief exposure to heat or cold, however excessive exposure to extreme temperatures will suppress reporting of some results since the extensive built-in QC mechanisms protect against reporting of results for analytes potentially compromised.


Do rotors require warm-up time before use? If used cold, any potential for inaccurate results?

No. Rotors can be used one at a time directly from the refrigerator.


Is the VetScan a ‘one test at a time’ type system?

No, there are 23 assays in 8 preconfigured panels to give the utmost flexibility while requiring seconds of hands on time and the lowest possible operating costs


Does the VetScan require calibration?

The VetScan is self-calibrating. There are two aspects to calibration –

1) instrument calibration

2) reagent calibration

The VetScan measures the optical absorbance to determine the concentration of the analyte. The instrument calibrates the optics automatically for each measurement. Unlike any other system, the VetScan reagents are factory calibrated and the calibration values are communicated to the analyser through the bar code on the rotor.


Can rotors be frozen and used later?

Rotors must not be frozen. Rotors should be refrigerated at 2 – 8 ° C.


What types of samples can be used with the VetScan?

Lithium-heparin whole blood, lithium-heparin plasma or serum. No sample preparation is required. Do not use EDTA as an anti-coagulant.


Can samples such as pig or goat be used with the VetScan?

Abaxis UK has conducted field studies to determine reference ranges for cats, dogs, horses and cows. Other species, such as pig, goat, etc. can be run on the VetScan. Select ‘OTHER’ for species type and refer to an established source or generate your own normal ranges.


What is the VetScan’s warm up time?

There is no warm up time. The VetScan is always ready to go


What is the proper order of sample collection when filling multiple tubes?

White top tubes (no additive), orange top tubes (lithium-heparin) and pink top tubes (EDTA) (Colours may vary depending on supplier). The VetScan iQC will recognize interference due to EDTA contamination through effects (ie: K+) should it inadvertently occur.


What are the power requirements needed to operate the analyser?

The analyser requires 100 – 200 volts AC, 50 – 60 Hz or 12 – 15 volts DC. The VetScan may be operated by utilizing the included power supply, a 12-volt battery or auto cigarette lighter adapter.


Is surge protection or an uninterruptible power supply required for the VetScan instrument?

Abaxis UK recommends that the VetScan be plugged into a surge protector designed for use with a computer. Abaxis UK recommends the use of an uninterruptible power supply (UPS) if the VetScan will be used in an area prone to electrical surges or power outages.


What do the black diamonds on the result card mean?

The three black diamonds mean that the iQC algorithm is functioning correctly and that results for that particular chemistry analysis were suppressed. If the VetScan analyser is unable to assure reliable results as a result of sample quality, endogenous substances or immeasurable analysis, it will suppress the results as opposed to simply reporting unreliable ‘numbers’.


Can the analyser be connected to an external computer?

The VetScan can be connected to an external computer. Sample results and status reports are automatically transmitted to the RS232 port of the analyser every time they are calculated or prepared. Popular terminal emulation software, such as Windows 95 HyperTerminal may be used to collect the data from the VetScan. The data is delivered in raw ASCII format and may easily be converted to text for formatting in other applications. The VetScan also interfaces with many commercial veterinary data management software packages. Check with your software vendor or Abaxis UK Technical Support for compatible programs.
