K Appendix: Differences in Results
With a Commercial Laboratory or Other Instrument
Reference ranges must be created for each analyte and each new instrument or
method of analysis. Every commercial laboratory must establish its own species
reference ranges for the equipment and methodology used. IDEXX is continually doing
this work for you with every software release (see Your Participation in Reference Range

using different equipment or methods is imprecise at best. Any comparisons should be
performed on the same sample that has been split, stored under like conditions, and
tested at approximately the same time. Comparisons of values must take into account
differences in the corresponding reference ranges.
With Your Own Expectations
If you receive results that are not what you expected for a particular patient, consider
the following:

important minor changes become. For example, a significant result for ALKP would
be 3 times the upper end of the reference range.

All laboratory results should be interpreted in light of the case history, the clinical signs,
and the results of ancillary tests.
