COMPARE · SIPHOX HEALTH + LIBBY

SiPhox tests at home. Libby remembers.

SiPhox Health runs an at-home blood panel in its own dashboard. Libby is the lifelong record those results live in — import the PDF and it joins one timeline with your Quest, LabCorp, and doctor's labs, ready for AI or a clinician.

Libby is a companion to an at-home testing service, not a replacement for the draw.

DIFFERENT CATEGORIES · DIFFERENT JOBS

Two things that work better together.

SiPhox is a genuinely convenient way to get blood work without a lab visit. The question its own users ask most is now that I have these numbers, where do they live, and how do I read them against everything else? — the gap a record you own fills.

The at-home test

SiPhox Health

At-home sample collection mailed to CLIA-certified labs across a broad biomarker panel, with results in a clean app — convenient, repeatable blood work without a lab visit. Check their site for current panels and pricing.

The record you own

Libby

Imports your SiPhox PDF and every other lab, reconciles the units, and files each marker onto one lifelong timeline you own and can export — so a recurring at-home panel becomes one history you can track and hand to AI or a clinician.

SIDE BY SIDE

SiPhox Health vs. a record you own.

Read this as “these do different things,” not “one wins.” Many people keep an at-home testing service and a record they own — the service tests, the record remembers.

QUESTIONS · SIPHOX HEALTH + LIBBY

A few things worth knowing.

Is Libby an alternative to SiPhox Health?
Not exactly — they do different jobs. SiPhox is an at-home testing service that draws blood and runs a panel. Libby doesn't test; it's the record your SiPhox results (and every other lab) live in over time. If you want a durable, cross-source home for results, Libby complements SiPhox rather than replacing the test.
Can I keep my SiPhox results if I stop testing there?
Yes. Export your results as a PDF and import them into Libby, and they stay with you regardless of your testing status. Owning a copy is the point.
Can I combine my SiPhox results with my Quest and LabCorp labs?
Yes. Libby consolidates results across providers onto one timeline, reconciling different units and marker names so a SiPhox reading lines up with an older Quest or LabCorp draw.
Does Libby draw blood like SiPhox?
No. Libby doesn't collect samples or sell panels. You bring results from SiPhox, Quest, LabCorp, Function, or your doctor, and it tracks them over years and makes them usable with an AI or a clinician.
