Hello friend, I’m Rachel.
GuidedGut isn’t a brand. It’s simply a place to dig deeper into iron deficiency anemia, SIBO, gut dysbiosis, and mold illness, and to share the tools and information I wish I’d had during my own recovery.
Recovery can be confusing and expensive, and I am here to help you.
Functional lab price tracker
Secret: Lab tests don’t have to cost you hundreds.
To spare you the painstaking hunt, I keep the lab prices updated with the lowest options I find so you can spend less on testing and more on your recovery. My naturopath referred me to Jason Health as a self pay patient. It took the financial anxiety and pressure off getting labwork. At GuidedGut, I compare what it actually costs to order the GI-MAP, SIBO breath tests, iron panels and even home mold tests online. You can spend your recovery budget on your recovery journey. Every lab price is current on the seller’s own page, with the date I checked it, so you can begin anytime at the most affordable way.
- $497lowest GI-MAP total I verified
- $269lowest 2-gas SIBO kit
- $15lowest ferritin test
- 27/27listings with a verified price
No insurance? Me neither. Basic blood work like ferritin and an iron panel can cost far less than you'd think. Start here: affordable labs without insurance →
♥ A note from Rachel:
My first GI-MAP changed my life. It showed me the data behind my symptoms so I could stop worrying and start fixing. I get a GI-MAP every 6 months and admire my progress.
Please remember I’m not a doctor; this is a helpful price list plus my own experience. Please make testing decisions with your practitioner.
