2-6 General Information
■ If a rotor was exposed to heat do I risk unreliable results as with other systems? Or if
it’s run too cold?
Always store rotors in the appropriate conditions to help ensure accurate results. Rotors
may tolerate brief exposure to heat or cold, but excessive exposure to extreme tempera-
tures suppresses reporting of some results, since the VS2’s extensive built-in iQC mecha-
nisms protect against reporting results for potentially compromised analytes.
■ Do rotors require warm-up before use?
No. In fact, you should use rotors directly from the refrigerator.
Testing and Results
■ Does hemolysis, lipemia, or icterus affect the results on the VetScan VS2?
Endogenous substances such as hemolysis, lipemia, and icterus affect all blood chemis-
tries, regardless of the type, size, or cost of the analysis instrument.
The VetScan VS2 is the only point-of-care analyzer that assesses and suppresses hemoly-
sis, lipemia, and icterus by determining assay-by-assay the level at which these substances
could affect the reliability of the results, and bringing this to the user’s attention.
■ What do the tilde (~ ~ ~) symbols in the results mean?
These symbols mean that the VS2’s iQC algorithm is functioning correctly and results for
that particular chemistry analysis were suppressed. If the VS2 cannot assure reliable
results because of sample quality, endogenous substances, or unmeasurable analysis, the
analyzer suppresses the results rather than simply report unreliable numbers.
■ What happens if I run a rotor under the wrong species?
The analyzer is specifically calibrated for different species. If a rotor is run under the
wrong species bank, the results will be unusable, and the rotor must be run again under the
correct species.
■ Can the VS2 results be transmitted to my lab management software?
Most lab management software is compatible with Abaxis equipment. Check with your
software company to be certain.
