Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (10)

compare-pricesread-onlyCompare the all-in price of one JustLabs test or panel (catalogue id such as tsh, or a test name) with published prices from other direct-to-consumer lab services: each one's price, per-order fees and all-in total, whether it covers the same tests, the source link and the date checked. JustLabs all-in = price + one $18 order fee. Product terms only.
compare-providerread-onlyHow JustLabs compares with another lab-testing provider (e.g. everlywell, testwell, quest, labcorp): a short verdict, side-by-side facts with sources, where each one is the better choice, FAQs and a link to the full comparison page. Product terms only.
find-draw-sitesread-onlyFind Quest Diagnostics patient service centers (blood-draw sites) near a 5-digit US ZIP code where a JustLabs order can be collected: site code, address, distance, hours, walk-ins and a booking link, optionally with the next open appointment times. Send only a ZIP code — never a street address, name or contact details. The response names the states where JustLabs does not accept orders.
get-guideread-onlyRead a public JustLabs guide page as Markdown, e.g. /blood-test-preparation, /labs-for/hypothyroidism, /tests/tsh or /compare/everlywell. Pass a justlabs.health path starting with /, not a full URL. Account, checkout, results, admin and API paths are refused. Educational content; any range on the patient's own lab report applies.
get-pricingGet the exact all-in price for one or more JustLabs test or panel IDs: each item's price, the single $18 per-order lab & physician fee (charged once per order), and the total — the same amount checkout charges. Pass an optional 2-letter US state to check whether the order can be placed there.
get-test-detailsGet full details for a specific lab test or panel by its ID. Returns pricing, biomarkers (or included tests for a panel), preparation instructions, and turnaround time.
get-test-panelsGet available test panels and compare panel base prices with their included tests bought separately. One $18 lab & physician order fee applies once per order.
lookup-reference-rangeread-onlyTypical reference ranges for a lab marker (e.g. TSH, ferritin, LDL cholesterol, vitamin D), optionally by sex and age, with unit, source and the JustLabs test that measures it. Educational only: ranges vary by lab and method, and the range printed on the patient's own lab report applies. Product terms only — send the marker name, never a result value, name, date of birth or other personal details. It does not interpret results.
recommend-testsread-onlySuggest JustLabs panels and tests for health goals (e.g. energy, heart health, fertility) and/or symptoms (e.g. fatigue, hair loss), each with a one-line reason, price, all-in price and link, plus the JustLabs guide pages the suggestion is based on. General education, not a diagnosis. Pass short goal or symptom words only — no names, contact details, dates of birth or lab results. Use get-pricing with the ids for the exact total.
search-lab-testsSearch the JustLabs catalog of tests AND panels by test name, condition (e.g. menopause, gout, anemia), category, or biomarker. Use only product terms; do not include names, contact details, symptoms, or personal lab results. Prices are per test; one $18 lab & physician order fee is added once per order. Use get-pricing for the exact total.
