Your blood test results deserve more than a PDF you'll never open again.

Sanguine extracts your lab results, shows you where you actually stand, and tracks the trends that matter — not just what's "normal."

Vitamin D

Lab range: 20–80
Optimal range: 50–80
! In lab range, but below optimal. Consider supplementation and retesting in 3 months.
Hemoglobin A1c

Lab range: 4.0–5.6
Optimal range: 4.8–5.2
Within optimal range. Your glucose control is strong.
73% of adults have at least one blood test result stored as a PDF or printed document they can't act on.

Blood tests are the most data-rich signal in healthcare. And yet most people's results live in email attachments, filing cabinets, or Google Drive folders — invisible, untracked, unreadable. Lab ranges are wide enough to make almost anything look normal. Your actual health data is doing nothing for you.

Watch your trends

See your biomarkers plotted over time. Is your Vitamin D climbing? Is ferritin creeping up year over year? Trends that your doctor doesn't have time to show you — visible at a glance.

Optimal range, not lab range

Lab ranges are designed to detect disease. Sanguine shows you where the optimal zone is — the range where you're not just "not sick" but actually thriving. Your data, presented at the level you deserve.

AI that knows your history

Ask questions about your results in plain language. Sanguine's AI considers your full history — not just your latest test — and gives you context-aware answers. "Your iron has been rising across your last three tests. Worth investigating."

Lab range vs. optimal range.
It's a meaningful difference.

Labs define "normal" by what's common among sick people. The optimal range is tighter, more targeted — it reflects where your biomarkers need to be for genuine health and performance, not just the absence of a diagnosable condition.
