feat: add Common Lab Codes for India (CLCI · LOINC) - #1
Merged
Conversation
Add the Common Lab Codes for India (CLCI), a curated subset of LOINC v2.82
(1,473 tests), as a self-contained module keyed on LOINC code:
- src/lib/labs: types, curated LOINC glossary, discipline categories, client data layer
- scripts/lib/loinc.ts: CSV parse + best-effort/validated FSN decomposition (+ tests)
- scripts/build-labs.ts: emits public/data/labs/{tests,manifest}.json
- scope the drug build's cleanup so the two builds coexist under public/data
- package.json: build:data chains drugs then labs; add test:labs; bump 0.1.0 -> 0.2.0

Summary
Adds Common Lab Codes for India (CLCI) — a curated subset of LOINC v2.82 (1,473 lab tests) published by NRCeS/C-DAC — as a second terminology alongside the existing drug codes. The site becomes a two-section "Clinical Codes Browser" hub: Drugs (CDCI · SNOMED, unchanged) and Lab tests (CLCI · LOINC, new).
Labs data pipeline & module (self-contained, keyed on LOINC code — a separate identity space from SNOMED, so no drug code paths change)

/labs: instant in-memory search + facet rails (Discipline, Scale, Specimen) with counts, mobile-collapsible,aria-pressed, deep-linkable (?q=/?category=/?specimen=)/lab: decodes a test's cryptic LOINC FSN into six plain-English axes, with the Long Common Name as authoritative and a graceful raw-FSN fallback for the ~22 rows that don't cleanly parse; LOINC code / FHIR Coding copy; related-by-specimen<head>metadata; off-palette substance badge tokenizedThe "split": e.g.
ACnc→"Arbitrary concentration",Ser→"Serum",Qn→"Quantitative". Discipline categories (Chemistry, Hematology, Microbiology, Molecular, …) are derived by a transparent heuristic with a reviewabledata/source/clci/categories.jsonoverride file. CARE lab export is deferred to v2.Test Coverage
scripts/lib/loinc.test.ts— 12 checks over the pure parse/validate/derive helpers: FSN with/without method, no-colon rows, drifted-split rejection, scale whitelist, specimen/scale facet derivation,^super-systemcollapsing, immunoglobulin word-boundary matching, category derivation, CSV edge cases.Pre-Landing Review
A multi-agent adversarial review (3 dimensions → per-finding verification) confirmed 10 of 12 findings; all 10 were fixed and re-verified: deep-link facet resync,
aria-pressedon chips, mobile-collapsible facet rail, immunology regex word-boundaries (dropped exactly 1 false positive, 485→484), specimen^super-systemstripping (63→61 clean labels), component-axis gloss, specimen "See all" drill-down, dead import, off-palette badge token, build-cleanup scoping.Design Review
Live-dogfooded every flow (home,
/labssearch + facet filtering, parsed + unparsed detail, deep-links, mobile collapse) — zero console errors. Token-only styling consistent with the existing teal palette.Verification
npm run typecheckcleannpm run build(drug + lab data builds + static export) succeeds — all 7 routes export staticallynpm run test:labs— 12/12 passTest plan
