Potential side effects

Inferred read-only

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.

Inferred read-only

find_draw_sites

Find Quest Diagnostics, Labcorp and BioReference patient service centers near a US ZIP code, with address, distance, phone and hours.

Inferred read-only

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.

Inferred read-only

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 hospital self-pay and Quest Direct reference prices.

Potential side effects

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, its high/low interpretation page.

Inferred read-only

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.

Inferred read-only

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'.

Inferred read-only

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 sources.

Inferred read-only

get_guide

Return one of TestWell's educational pages as Markdown: guides (/guides/<slug>), condition workups (/conditions/<slug>), test decision guides (/answers/<slug>), biomarker pages (/biomarkers/<slug>), state pages (/lab-locations/<slug>) or comparisons (/compare/<slug>).
