Secret: Lab tests don’t have to cost you hundreds.
My naturopath referred me to Jason Health as a self-pay patient. It took the financial anxiety and pressure off getting labwork. At GuidedGut, we compare what it actually costs to order the GI-MAP, SIBO breath tests, iron panels and even home mold tests online, so you can spend your recovery budget on your recovery journey. To spare you the hunt, every price is one we saw on the seller’s own page, with the date we checked it.
- $497lowest GI-MAP total we verified
- $269lowest 2-gas SIBO kit
- $15lowest ferritin test
- 27/33listings 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.
