We offer a variety of chemistry group tests (e.g. small and large animal panels) for both mammalian and non-mammalian species. Some of our chemistry tests are not incorporated as panels and have to be requested individually. We prefer serum (red top tube) for chemistry testing (all our reference intervals are based on serum), with the exception of stat samples and samples submitted after 3 00 pm. The latter samples should be submitted in heparin (green top tube). Please refer to Sample Submission for more information on the required samples for chemistry tests. There are some differences in reference intervals for some analytes in serum versus heparinized plasma. Please refer to our Reference Intervals for more information.
We use an automated wet chemistry analyzer, the Roche Mod P, for our chemistry tests. As well as performing chemistry tests themselves, the Hitachi provides useful information about interferences in the sample. This is shown on our chemistry reports as special chemistry tests, the lipemic, hemolytic, and icteric indices. Some of our tests are also performed using other instrumentation. For example, patients on bromide therapy have artefactually high chloride (because bromide and chloride are both measured in the assay) with the Hitachi, but our bench instrument, the chloridometer, is less affected by this artefact. For this reason, it is always good practice to inform the laboratory of any medication the patient may be on so that we can modify our methods (if necessary). This is especially important in samples drawn after administration of hemoglobin-based oxygen carriers (e.g. oxyglobin), which are colored compounds that affect the results of many chemistry tests.
All of our chemistry tests that are components within panels can be ordered individually, rather than as group tests. This is useful for research samples.
View the chemistry group test page for detailed reports on certain tests and to obtain more information about the individual components of each test, click on the test name below. For those tests that do not have links, most of the information can be gleaned from the other panels which include the same tests (mostly small and large animal panels).
View the chemistry individual test page for components of our panels can be ordered individually. There are also some tests that are not included in the panel, which must be ordered as individual tests. Click on certain tests to obtain more information. Please refer to our Chemistry Module for additional information about the tests, including disease associations.
