Partnership for the Accurate Testing of Hormones (PATH)

Good health depends on having the right hormone levels in our bodies. Tests for hormones in blood help healthcare providers to better detect, treat and prevent diseases – but not all hormone tests are accurate.

In order to assure that health care providers can make the right decisions and improve patient care and human health, The Endocrine Society has undertaken a collaboration with the Centers for Disease Control (CDC) and others to establish the Partnership for the Accurate Testing of Hormones (PATH).


Improved patient care and public health through universal use of accurate and reliable hormone tests in healthcare and research.


To advance the development of standardized hormone assays that are traceable to a single higher order reference material and method (gold standard), and to advocate for the universal adoption of these assays in medical practice and research.

The PATH website is under construction, with expected completion early 2014. The site will provide a wealth of information on hormone testing, including testosterone, estradiol, vitamin D, and thyroid. The 2010 consensus statement, published in the Journal of Clinical Endocrinology and Metabolism, presents recommendations for improving testosterone testing and was the founding document of PATH.
