Biomarker & Lab Catalog API
One API for biomarkers, lab catalogs, and clinical evidence.
Look up any analyte, such as ApoB, Ferritin, or HbA1c, by name or LOINC code. Get back the Quest and Labcorp tests that measure it, attributed reference ranges, and curated conditions with the guideline or study behind each link.
Stop maintaining brittle lab spreadsheets in-house.

ApoB appears in 5 Quest tests. One of them, the Cardiometabolic Disease Assessment (CMDA) Panel (#14273), also measures TSH and HbA1c.

Data model
Map proprietary lab test codes to the analytes they measure.
Commercial labs organize their catalogs around proprietary test codes and panels. Guidelines and studies organize around analytes and conditions.
Analyte Atlas connects both sides at the biomarker, so your product can go from a Labcorp test code to the guideline behind a range in a few calls.
- Biomarkers
- Standardize analyte names across labs with canonical keys, aliases, primary units, and LOINC codes. Look up Ferritin by name, alias, or LOINC 2276-4.
- Lab tests
- Find every Quest and Labcorp test that measures an analyte, with the lab's test code, specimen, patient preparation, turnaround, and CPT codes. Filter single-analyte tests from panels.
- Reference ranges
- Show lab intervals and guideline targets with their publisher, population, and unit, plus the range rows each lab prints on its test page.
- Goals and conditions
- Connect biomarkers to curated goals, such as iron deficiency, and to conditions with ICD-10-CM codes. Each link cites a guideline or study.
- Labs
- See which lab catalogs we load, how many tests and analytes each contributes, and when we retrieved it.
- Evidence
- List every source behind a biomarker: lab catalog pages, cited references, and a ClinicalTrials.gov search link for the analyte.
Provenance
Pass clinical and legal review without black-box guesswork.
Health products cannot rely on unverified LLM summaries. We attach a source to every fact the API returns: the lab's catalog page for each test, and the guideline or study for each curated condition and range.
Each source names its type, publisher, URL, year, and PubMed ID where one exists.
Show your users the reference range each lab or guideline body publishes for its assay and population. We attribute every range to its publisher, unit, and population group, so your product never displays a one-size-fits-all “normal range.”

Use cases
Stop paying engineers and clinicians to maintain biomarker spreadsheets.
Consumer lab and preventive health apps
Show reference information next to lab results, map Quest and Labcorp test codes to the same analytes, and design test panels without staffing an internal curation team.
Diagnostics companies and laboratories
Compare your test menu with Quest and Labcorp panels, spot analyte coverage gaps by lab, and check which tests measure a single analyte.
Pharma medical affairs and biomarker teams
Map biomarkers to curated conditions with ICD-10-CM codes, find the commercial tests that measure them, and pull the cited sources for medical review.
