How the Canary Process Works (Patient to Inspector to Results)

How it works · Published 2026-05-31 · 6 min read · Reviewed by Canary Clinical Advisory Board

Canary is a marketplace, not a clinic. Here is exactly how a booking flows — from the moment you describe your concern to the moment a lab report and any documentation land in your hands.

What Canary is

Canary is a marketplace that connects patients with certified environmental and home inspectors, and — when it is clinically appropriate — with licensed telehealth providers who can issue a Letter of Medical Necessity. We are not a healthcare provider, we do not diagnose, and we do not analyze samples ourselves. We coordinate independent professionals and hand you clear documentation.

Step 1 — Tell us your concern

You start by describing what is going on: the home, the symptoms' timing if any, the water history, and what you are worried about. This intake shapes which tests make sense and whether a provider review is relevant.

Step 2 — Optional clinical review

If you intend to use HSA/FSA funds, a licensed provider in our network can review your situation by telehealth and, if appropriate, issue a Letter of Medical Necessity. This step is about documentation and clinical judgment; it does not guarantee that your administrator will reimburse the expense.

Step 3 — Match with a certified inspector

We connect you with a certified inspector serving your area. You can review their credentials and book a visit. The inspector performs the on-site assessment and sampling and sends samples to an independent accredited lab.

Step 4 — Get your results

When the lab finishes, your results land in one place. Your report folder typically includes:

That package is the kind of documentation a clinician can interpret and an HSA/FSA administrator may ask to see.

Step 5 — What you do with it

You bring the results to your treating clinician to discuss what, if anything, they mean for your health, and — if you are seeking reimbursement — you submit the LMN and receipt to your HSA/FSA administrator per their instructions. Canary does not submit on your behalf and cannot promise reimbursement.

Privacy: Canary is built around protecting your information. Your clinical details are handled with care and are never part of public pages like this one. See our privacy policy for specifics.

Frequently asked questions

Is Canary a doctor's office?

No. Canary is a marketplace that coordinates independent certified inspectors and, when appropriate, licensed telehealth providers. We do not diagnose or treat.

Do I have to get a Letter of Medical Necessity?

No. The clinical review and LMN are optional and mainly relevant if you plan to use HSA/FSA funds. You can book an inspection on its own.

Will Canary file my HSA/FSA claim for me?

No. We provide the documentation administrators commonly request, but you submit it to your administrator, who decides on reimbursement.
