Test Result Harmonization Status

Harmonization status indicates equivalency of results across platforms and vendors, ie, a harmonized test for a particular analyte and specimen yield results equivalent to other harmonized tests for that analyte and specimen. Harmonization is required for full clinical interoperability of test results. Results from harmonized tests may be interpreted and trended together, and may use the same calculation and decision support rules. Machine learning models may be trained and applied to data sets from different test platforms and vendors if the tests are harmonized. Tests that are not harmonized do not yield comparable results and should be interpreted and processed separately, not in aggregate with other tests. Incorrect assumption of harmonization status is a serious patient safety risk, and lack of harmonization information impedes public health interpretation of test results.


Test Result Harmonization Status

  • Data Class: Laboratory
  • Data Element: Test Result Harmonization Status
  • CAP Comment: The College of American Pathologists (CAP) applauds the ONC’s decision to add this data element at the Comment Level. The CAP’s recommendations for the format and content of this data element will be forthcoming.
  • Technical Correction: The CAP would also like to suggest a change in the content of the USCDI Web page that describes this data element. The text under “information from submission form” on that page includes all the text from multiple data elements. This obscures the text about the Test Result Harmonization Status element. The CAP would suggest that the text on other data elements be deleted on that page so that the explanation of the harmonization status element is clear.
