What I'm building now.

LIBBY HEALTH · BY ZEBRA DIAGNOSTICSLive · v 0.1

A quiet record of your health.

Libby Health is a personal health record on the way to a personal healthcare agent — a product from Zebra Diagnostics, on the path to the diagnostic revolution.

Today, Libby is the record. Upload your lab PDFs from Quest, LabCorp, or anywhere else; Libby extracts the values, tracks them over time as painted visualizations, and overlays functional reference ranges on the standard lab ranges. The point is to see trends, not snapshots.

Built from the ground up for record aggregation and understanding — so the data is in the right shape to support context-rich conversations with an LLM.

Behind the scenes we’re building personal healthcare agents. Libby is the surface for that work: the record first, the agent next.
