Our previous PTHrP assay remains unavailable, and we apologize for the impact on our clients' daily practice. We continue to encourage the use of our Basic Parathyroid Panel or Vitamin D Profile during this time. To provide a deeper overview of how to maximize measurement of PTH, ionized calcium, and vitamin D without PTHrP, we published an article we hope will be helpful. Read it to learn more about commonly encountered patterns of results and their interpretations. β¬οΈ

We are still actively working on an alternate test method to measure PTHrP and hope to have it available as soon as possible.
While our PTHrP (parathyroid hormone-related protein) assay remains unavailable, this article provides an overview of how to best utilize and interpret available assays without measurement of PTHrP.
