Public Biomarker & Lab Reference · Free & Open
See the full clinical picture across biomarkers, health goals, and lab tests.
Look up individual markers like Ferritin, ApoB, and HbA1c to see what they signal, or start from a goal like iron deficiency, heart health, or energy and fatigue to find the right biomarkers to test.
Compare companion markers, Quest and Labcorp tests, and lab reference ranges alongside guideline targets and published evidence.
Choose the right tests, check the source behind every range on your lab report, and interpret your own numbers with a clinician.
Look up 5,966 biomarkers across 7,065 tests from Quest Diagnostics and Labcorp
Low body iron stores, with or without anemia, as measured by serum ferritin and the related iron tests.

Use cases
Find which biomarkers matter for your goals, choose the right lab assays, and look up the markers on your lab report.
Find which biomarkers matter for your goals
Start with a health goal like iron deficiency, heart health, or energy and fatigue, or a condition like prediabetes, to see the primary and companion biomarkers a named guideline or study connects to it.
Compare commercial assays before you order
When ordering self-directed labs, check the exact commercial catalog codes, specimen types, and analytical methods (such as hs-CRP vs. standard CRP, LC/MS vs. immunoassay, or RBC vs. serum minerals) so you order the right test.
Prepare for a clinician visit or lab draw
Decode the abbreviations on a doctor's lab order, verify fasting and time-of-day collection rules before your draw, and bring an evidence-backed list of companion markers to discuss with your clinician.
Look up the markers on your lab report
Find each marker on your report, the physiological state the marker signals, and the companion biomarkers labs report with it. Compare the reference range your lab publishes for your age and sex with guideline targets, then interpret your own numbers with a clinician or in Aumnivida.
Beyond a single “normal” flag
Distinguish lab population averages from optimal targets and internet noise.
Commercial laboratories usually calculate a standard reference range from the statistical middle 95% of people who take that test, not from a threshold for optimal health or low disease risk.
Meanwhile, many consumer health blogs omit or simplify the numbers, and social media influencers often quote rigid or conflicting target levels, focus on certain outcomes in isolation, or lack clinical rigor in their claims. Biomarker Lens gives you the analytical facts in plain language.
Compare the five kinds of range for ferritin, ApoB and HbA1c.
01
Compare lab reference ranges with guideline targets and studies
See the exact reference ranges laboratories publish for specific age, sex, and life-stage groups.
Compare those reference ranges with guideline targets, diagnostic cut-offs, and the ranges outcome studies report, each with the population it applies to.
02
Evaluate connected panels instead of isolated markers
You rarely get the full story from a single biomarker in isolation.
Checking Ferritin alongside Transferrin Saturation and hs-CRP helps spot iron deficiency even during inflammation, while pairing LDL-C with ApoB and Lp(a) shows particle count and inherited risk together.
03
Match generic test names to exact laboratory assays
Laboratories often offer multiple assays for the same biomarker using different methods, units, or specimen rules, such as standard immunoassay vs. LC/MS hormone testing or serum vs. RBC minerals.
We list the exact commercial test codes, specimen types, and preparation rules for each laboratory.
How it works
Get the complete clinical and laboratory breakdown on one page.
01
Understand the physiological signal and connected markers
See the conditions and health goals a biomarker reflects, with the source for each link, and the companion markers labs report in the same panels.
02
Match standard identifiers and lab aliases
Connect any biomarker across alternate commercial lab names, standard measurement units, and LOINC identifiers so you can tell when two laboratories measure the same analyte.
03
Compare orderable lab assays and prep rules
Review the Quest and Labcorp tests that measure the biomarker, including catalog codes, specimen types, methods, fasting requirements, and turnaround times, and compare up to five side by side.
04
Check demographic ranges and primary sources
Compare laboratory reference ranges by age and sex with guideline targets and study-based ranges. Open the lab catalog page behind every test and the guideline or study behind every curated target.
Sources
Verify every range and claim against primary clinical and laboratory sources.
We build every page from a clinical knowledge graph that connects the Quest Diagnostics and Labcorp test directories, guidelines and outcome studies, and LOINC terminology. Check the lab catalog page behind every test and reference range, and the guideline or study behind every curated target and goal link. See every source.
Check commercial laboratory catalogs
Verify orderable test codes, analytical methods, specimen and fasting rules, and reference ranges in the Quest Diagnostics and Labcorp test directories, with each test linked to its catalog page.
Inspect peer-reviewed studies and guidelines
See the medical society guidelines and outcome studies behind every curated target, cut-off, and goal link, each with the population it applies to.
Search registered clinical trials
Open the ClinicalTrials.gov search from any biomarker page to find interventional and observational studies that measure the biomarker.
Cross-reference LOINC clinical standards
Use universal laboratory identifiers and canonical unit mappings to connect differently named tests across commercial laboratories to the same underlying biomarker.
