How the Analysis Works

Drop your PDF, take a photo of your lab report, or type values manually. We support reports from labs worldwide.
We compare against clinical ranges
Each marker is evaluated against reference ranges from the NIH, AHA, CDC, and other major medical authorities.
See how your markers connect
Individual markers only tell part of the story. We identify patterns across your results — combinations that doctors look for but lab printouts don't show.
Get a clear action plan
Prioritized steps based on your specific results: what to discuss with your doctor, lifestyle changes, and when to retest.

What We Are Not

BloodMarker is not a medical provider. We do not diagnose conditions, prescribe treatments, or replace your doctor. Our content is educational — designed to help you understand your results and have better conversations with your healthcare provider.
