An offline-friendly lookup tool for matching lab tests to tube colors, additives, and grouped draw counts.

Landing page captured for the 2026-09-15 issue.

Field notes

Phialex organizes phlebotomy references around two lookup directions: a test name returns tube color and additive information, while a tube color returns compatible tests. Users can assemble several tests and receive grouped per-color tube counts, a workflow intended to reduce duplicate sticks. The page describes an installable Progressive Web App with offline use and no account requirement, while also linking to security, privacy, FAQ, contact, and changelog material.
