Praetor Health

Use this when the user explicitly asks to compare two to four known Praetor Health blood-test slugs. 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 exact slugs are not known, use search_blood_tests once and answer from that result instead. Compare differences 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 when the user explicitly asks to open or show details for one known Praetor Health blood-test slug. 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 a recommendation. It does not access customer accounts, orders, results or reports and does not determine medical suitability.
