## Tools (as reported by the server, not verified)

- `search\_tests`: Search TestWell's public catalog of cash-pay lab tests and panels by keyword, biomarker, CPT code, or category. Returns name, slug, per-lab prices, sample, fasting, turnaround and order URL. Prices are stickers; every order adds one $6 lab processing fee \(see quote\_order for all-in totals\).
- `get\_test`: Full public detail for one TestWell test or panel by slug or id: description, biomarkers, CPT, per-lab prices, labs, fasting/prep, turnaround, included tests \(panels\), FAQ, related conditions, order URL and a Markdown page URL. Tests also carry labPages — per-lab pages \(/tests/\<slug\>/quest, /tests/\<
- `list\_panels`: List TestWell's bundled panels \(multi-test packages priced below the sum of their tests\), optionally filtered by category or maximum price. Sorted by price.
- `recommend\_tests`: Suggest TestWell panels and tests for stated health goals \(e.g. 'annual checkup', 'heart health', 'TRT monitoring'\) and/or symptoms \(e.g. 'fatigue', 'hair loss'\). Prefers a curated pre-built panel when one fits; otherwise assembles individual tests within a budget. Educational matching, not a diagno
- `quote\_order`: Price a set of tests/panels exactly as TestWell's checkout would: per-lab prices for the user's state \(New York and New Jersey route to BioReference; Rhode Island is not served\), the single $6 lab processing fee, the total, items that can't be ordered and why, and a prefilled cart URL. Use this befo
- `create\_checkout`: Start a TestWell order for the user: tests/panels, the US state where they will visit the lab \(required for pricing and lab routing\), and the buyer's name, email and phone. Returns priced line items in cents, the single $6 lab fee, the total, any blocking messages, and pay\_online\_url — a prefilled c
- `update\_checkout`: Change items, state or buyer details on an open checkout session and get it re-priced. Returns the same session object as create\_checkout.
- `get\_checkout`: Current state of a checkout session \(status, line items, totals, messages, order once paid\). Read-only.
- `cancel\_checkout`: Cancel an open \(unpaid\) checkout session. Paid sessions cannot be canceled here — the patient's complete-details email explains refunds.
- `complete\_checkout`: Charge the payment credential the platform obtained for a session that is ready\_for\_payment and create the order. Input follows the ChatGPT payment-sheet contract: checkout\_session\_id, buyer, payment\_data \{ token, provider: 'stripe', billing\_address \}. The token is a Stripe shared payment token \(spt
- `find\_draw\_sites`: Find Quest Diagnostics, Labcorp and BioReference patient service centers near a US ZIP code, with address, distance, phone and hours. Walk-ins are accepted at most sites; the requisition arrives by email after physician authorization. Sites in the 48 tracked metros include pageUrl — the site's own p
- `lookup\_reference\_range`: Physician-reviewed reference range for a blood test marker \(130+ markers\), filtered by sex and age when they matter, with what high and low values suggest, retest cadence, how to get tested, cited sources and the review date. Educational; the user's own report range takes precedence.
- `compare\_prices`: For one blood test, the all-in single-test price \(sticker + per-order fees\) at TestWell and at every tracked direct-to-consumer provider with a verified equivalent — JustLabs, Quest, Labcorp OnDemand, Ulta Lab Tests, Walk-In Lab, HealthLabs and more — each with the date it was verified, plus typical
- `interpret\_results`: Flag each pasted lab value as low / normal / high against TestWell's physician-reviewed reference catalog \(130+ markers; sex- and age-specific bands where they exist\), with the reviewed 'what high/low suggests' copy, retest guidance, cited sources and links to the marker's page and, where one exists
- `convert\_units`: Convert a lab value between US conventional and SI units for 30 common analytes \(glucose, cholesterol, testosterone, vitamin D, …\) using published factors; hemoglobin A1c uses the NGSP↔IFCC master equation and also returns estimated average glucose.
- `calculate\_free\_testosterone`: Calculate free and bioavailable testosterone from total testosterone, SHBG and albumin using the Vermeulen \(1999\) mass-action equation — the method behind lab-reported 'calculated free testosterone'. Educational; not a diagnosis.
- `compare\_provider`: Honest side-by-side of TestWell and another direct-to-consumer lab service \(Quest Direct, Labcorp OnDemand, Function Health, JustLabs, Ulta Lab Tests, …\): pricing model, per-order fees, labs, turnaround, where each wins, spot prices on common tests as sticker AND all-in, with verification dates and
- `get\_guide`: Return one of TestWell's educational pages as Markdown: guides \(/guides/\<slug\>\), condition workups \(/conditions/\<slug\>\), biomarker pages \(/biomarkers/\<slug\>\), state pages \(/lab-locations/\<slug\>\) or comparisons \(/compare/\<slug\>\). Call with no path to list the available guides and conditions.
