The GI-MAP and DUTCH tests are industry-leading tools for helping patients improve their gut and hormonal health. Now, our laboratories are coming together to share how using the tests together can help practitioners successfully guide patients through perimenopause.

Join us on September 25th at 2 PM EST as Cat Simmons, MS, RD, from Diagnostic Solutions Laboratory, Jaclyn Smeaton, ND, from Precision Analytical, and practitioner Lexi Yoo, FNP-BC, CPNP, discuss how to use GI-MAP and DUTCH testing to understand the gut-hormone connection, individualize treatment protocols, and optimize outcomes for perimenopause patients.

Cat, Jaclyn, and Lexi will discuss the interplay between gut health, hormonal health, stress, and methylation and review a case study showing the powerful insights that can be gleaned from pairing GI-MAP and DUTCH testing.

Register to learn:

  • The role GI-MAP's beta-glucuronidase marker plays in gut health and perimenopause
  • How to evaluate estrogens and androgens with DUTCH testing
  • The role of methylation activity in perimenopause
  • How GI-MAP dysbiosis patterns and gut dysfunction impacts perimenopause patients through gut endocrine function
  • How the DUTCH adrenal assessment's urinary cortisol curve offers insight into stress, anxiety, and inflammation
  • About the indican marker on the DUTCH Test, which provides insight into leaky gut, digestive insufficiency and dysbiosis
