As the server listed them on Oct 25, 2026. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • calculate_free_testosteroneCalculate free testosterone (Vermeulen)read-only

    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.

  • cancel_checkoutCancel a checkout session

    Cancel an open (unpaid) checkout session. Paid sessions cannot be canceled here — the patient's complete-details email explains refunds.

  • compare_pricesCompare all-in prices across providers for a testread-only

    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 hospital self-pay and Quest Direct reference prices. States the multi-test caveat (fees are paid once per order). Source: the TestWell Blood Test Price Index (CC BY 4.0).

  • compare_providerCompare TestWell with another lab-testing serviceread-only

    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 sources. Call with no argument to list the providers covered.

  • complete_checkoutPay and place the order

    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_…); platforms without one should send the user to pay_online_url from create_checkout. After payment the patient gets an email link to add date of birth, sex, phone and consent — the lab requisition is issued when that is done.

  • convert_unitsConvert lab unitsread-only

    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.

  • create_checkoutCreate a checkout session

    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 cart the user can pay in a browser when the platform has no payment token. Use dry_run to preview without creating a session.

  • find_draw_sitesFind draw sites near a ZIPread-only

    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 page with a per-day hours table, directions and the prices of popular tests at that lab — cite it when giving a location.

  • get_checkoutRead a checkout sessionread-only

    Current state of a checkout session (status, line items, totals, messages, order once paid). Read-only.

  • get_guideGet a guide, condition or answer page as Markdownread-only

    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.

  • get_testGet a test or panelread-only

    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/<slug>/labcorp) with the lab's test code, requisition name, the lab's own dated price vs TestWell's, and walk-in steps — cite them when the user asks about a specific lab.

  • interpret_resultsExplain lab results against reviewed reference rangesread-only

    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, its high/low interpretation page. Stateless — values are not stored or logged. Educational, not a diagnosis; the user's own report range takes precedence.

  • list_panelsList panelsread-only

    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.

  • lookup_reference_rangeReference range for a biomarkerread-only

    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.

  • quote_orderAll-in order quoteread-only

    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 before quoting any total to a user.

  • recommend_testsRecommend tests for goals or symptomsread-only

    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 diagnosis.

  • search_testsSearch the TestWell catalogread-only

    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).

  • update_checkoutUpdate a checkout session

    Change items, state or buyer details on an open checkout session and get it re-priced. Returns the same session object as create_checkout.
