Praetor Health

Use this to compare two to four Praetor tests: markers they share, markers only in each test, whether one contains another, and the price and marker-count differences. It returns data only; call show_tests with view compare to display the comparison. It compares facts and never says which test is medically best.

compare_tests

Use this when the user explicitly asks to compare two to four known Praetor Health blood tests. Supply each canonical slug or exact slugified published title. Call it at most once. Do not call search_blood_tests or get_blood_test in the same turn, and do not call this after a discovery result because search_blood_tests already returns the public facts needed for an inline comparison. If the products cannot be identified by slug or published title, search once and answer from that result instead. Compare public product facts without declaring a medically best test. It does not diagnose, determine suitability, order a test or book a clinic.

compare_blood_tests

Use this when the user wants discovery or a product-level recommendation by test name, biomarker, category, collection method, eligibility, budget, goal, ordinary symptom, named condition or health concern. Set query to the user's complete request text. Do not omit, paraphrase or replace medical or urgent-care wording when adding inferred biomarkers or catalogue categories as optional structured filters. Its result contains the complete public product facts needed to explain and compare the returned tests. Call this tool at most once in a turn, and do not follow it with get_blood_test or compare_blood_tests in the same turn. When the user explicitly asks to compare named tests, call compare_blood_tests directly instead. When the user explicitly asks to open one known test, call get_blood_test directly instead. Recommendations must stay at product level: explain matching biomarker coverage, price, collection and breadth, but never diagnose, interpret personal results, recommend treatment, claim that a test confirms or rules out a condition, or state that it is medically suitable for an individual. Do not use this as a substitute for urgent care. It never orders a test or books a clinic.

search_blood_tests

Use this for the full public facts of one Praetor test: markers by category, preparation, every collection option with its total, turnaround and the neighbouring tiers. It returns data only; call show_tests with view detail to display the test. Accepts the slug or the published name written as a slug.

get_test

Use this to read Praetor Health's whole public UK catalogue in one call: every test, grouped by range, with who it is for, its test price, the lowest total including collection, collection methods, turnaround and markers. Choose the tests whose markers fit what the person wants to check, for any goal, topic, budget or collection preference, then call show_tests with their slugs, or with view families and range ids for a broad overview. Pass a budget as maxPriceMinor and a required collection method as collectionMethods, however the person words them; eligibility leaves out the other sex's tests. Show tests from a filtered list with view results, not families, which shows whole ranges. Reuse a full list for follow-up questions; call it again when the person's limits change. It draws nothing. These are product facts, not diagnosis, personal suitability or medical advice.

list_tests

Widget-only: loads the data for another view inside the Praetor explorer.

load_view

Use this when the user asks about one biomarker in connection with Praetor's tests: it returns Praetor's public summary, the marker's category and related markers, a link to the praetor.health guide, and the tests that include it. It returns data only: always follow it with show_tests (view biomarker, the same biomarker) so the person sees the card and the tests that include it. It is educational information, never an interpretation of anyone's results.

get_biomarker

Use this to display Praetor tests after a data tool: a families overview, the tests you chose (one range shows as a tier ladder), one test, a comparison of two to four tests, or one biomarker. Pass identifiers only (slugs, range ids, a biomarker name); every fact shown is read from Praetor's catalogue. Call it once per answer. The view lets the user compare, see what one test adds, open markers and continue to praetor.health to buy.

show_tests

Use this when the user explicitly asks to open or show details for one known Praetor Health blood test. Supply its canonical slug or exact slugified published title. Call it at most once. Do not call search_blood_tests or compare_blood_tests in the same turn, and do not use this after a discovery result merely to support an answer. It returns public catalogue facts only; it does not access customer accounts, orders, results or reports or determine medical suitability.
