Sources
We build every page from named public sources: lab catalogs for tests and reference intervals, and guidelines or studies for every curated target and goal link.
Look up 6,284 biomarkers that at least one lab test measures.
Laboratory catalogs
Test names, codes, specimens, methods, preparation, turnaround and reference intervals come from each lab's public test directory. Every test on a biomarker page links to its catalog page.

Reference sources
- LOINC, Regenstrief Institute, through the U.S. National Library of Medicine
- We match each result to its LOINC code, so two labs that name the same analyte differently land on one biomarker page. Each code links to its LOINC record.
- MedlinePlus, U.S. National Library of Medicine
- Plain-language biomarker descriptions, linked to the MedlinePlus page under each description. A page without one shows no description rather than one we wrote.
- ClinicalTrials.gov
- Each biomarker page links a registry search for studies that measure the biomarker. We link the search and do not count or summarize trials.

Rules we follow
- We never interpret your own result. Pages state what sources publish and for whom. Interpret your numbers with a licensed clinician, or track them in Aumnivida.
- Every range names its publisher and population. A lab interval shows the lab and the age and sex group it covers, never a universal “normal”.
- “Optimal” needs outcome evidence. We use the word only for a range a named guideline or outcome study defines, with the population it applies to. How the kinds differ.
- Practitioner targets carry a name and a date. We show who published the number, where and when, and whether it cites evidence.
- Missing data stays missing. We leave a section out, or write “not stated”, rather than fill a gap.
