TestWell Lab 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).

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.

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.

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.

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.

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.

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

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

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

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.

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.

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.
