How to Use Biomedical Testing to Find Problems Inside Your Body

Oct. 16, 2020

Back when we first started working with clients we ordered all the fancy tests for everyone who walked in the door. We tested the gut (not one test, but two), hormones, cortisol, and organic acids, to name a few. It got to be pretty expensive but it seemed to be the best way to figure out exactly what to do next. Our process has evolved over the years, and now we start with just simple, inexpensive blood chemistry. This saves our clients a ton of money and time, and they still get great results.

On the podcast today, NBT Scientific Director and coach Megan Hall and I discuss the advanced (and not-so-advanced) biomedical tests we’ve run for clients over the years. We talk about the ones we still use and the ones we quit - and why. Megan explains why you should be sceptical of genetic testing, and the wealth of information you can derive from basic blood chemistry. We also talk about, the software we use at NBT to give personalised predictions of problems in your body that can help you decide on further testing and/or actions you want to take. We also talk about some software improvements I’ve made recently.

Here’s the outline of this interview with Megan Hall:
