This concludes Part 1 of this series on some of the tests that, in our experience as a reference laboratory, are commonly ordered inappropriately. While each of you may find a different set of tests that fall into this category, it is my hope that by periodically reviewing test appropriateness, we can all find ways to improve. Some improvements require education, whereas others require procedural or systematic solutions. Some solutions are best addressed by those ordering the tests, whereas others are best addressed by those performing them. We look forward to hearing from you about ways that we at Mayo Medical Laboratories can help reduce test-ordering errors, as well as ways that you have found to do the same, striving to always assure that the right test is ordered, on the right patient, at the right time.

The algorithms and Hot Topic presentations referenced by me are available at, where you will also find the other parts of this series. You can also access issues of the Communiqué and our Test Catalog. For your convenience, our customer service phone number is 800.533.1710.
