1. Look into the quality of the tests you order. If the test is for testosterone, estradiol or vitamin D, ask your lab if it’s standardized. For other tests, get more details about how precision and reliability are gauged and achieved.
2. Keep up with the latest developments in hormone testing. Talk to professional associations about the importance of test quality and push for more support for standardization efforts and encourage your organization to join PATH.
3. Educate colleagues who may not be aware of how improved hormone testing leads directly to better patient care, less retesting, and more consistent diagnoses. One way to start is by creating a list of standardized tests and the labs that offer them as a reference guide for everyone who orders diagnostics.
