The focus of this course is to show you how to use functional lab testing to grow both your confidence as a practitioner AND a successful practice. It will help to unpack common concerns held by nutritional therapy practitioners about functional testing and will inspire you to start using functional tests in your practice.

Nutritional therapy practitioners often feel overwhelmed when it comes to functional testing –  there are lots of tests to choose from; they can be expensive and there can be apprehension around the time and knowledge needed to interpret them. This practical day will guide you through a number of popular functional tests so that you feel confident in using them in your practice.

The course will focus on a number of popular functional tests such as the DUTCH hormone panels, the GI 360 and comprehensive thyroid panels. It will also look at how functional testing differs from conventional serum testing (and how they can be used to compliment each other).

The course will also draw upon various case study presentations to give you a solid practical understanding of how to  interpret and translate findings into clinical recommendations.

The course will be delivered online via presentations and case study examples with online chat discussion. You will be provided with essential information, practical tips and take-home resources.

Who is leading the course?

Giulietta Durante CNHC, MBANT

Giulietta has been running a busy nutrition practice for over ten years. She specialises in women’s health and in conditions like endometriosis, PCOS and fibroids. Her main reason for focusing on women’s health stemmed from a frustration at the lack of options offered to her by her own doctors when trying to deal with her own hormonal challenges. 

Early on in her practice Giulietta realised that functional testing was key to developing personalised programmes so that her clients could achieve long lasting and sustainable positive changes in their health. As a result her clinic quickly flourished as many clients began to experience improvements in their health after many years of struggling with chronic conditions. 

In the past few years Giulietta has become passionate about teaching about the menstrual cycle and she has created a number of online programmes to educate and inspire others to learn about this very important topic. 

She cares deeply about providing accessible information about hormone health and is very active on social media (she is renowned for her fun but educational reels on Instagram). 

She is also the co-host of The FemmePowered Podcast, a show about hormone health, cyclical living and what it means to be a woman today
