Get Started

Welcome to LOINC! This guide will introduce you to the basics of LOINC and help you hit the ground running. Before we dive in, it's worth being clear about the problem LOINC will help you solve.

The Big Problem

You want to exchange health data, such as labs, vitals signs, or clinical documents, but local systems have different ways of identifying the same test or measurement. Fragmentation has created islands of isolation.

The Solution

Map your local test codes to a universal standard that every system can understand. This is where LOINC comes in. LOINC is the global lingua franca for identifying tests and observations.

The Result

Systems that actually recognize and aggregate data from other institutions, so that you can get clinical data when and where you need it. Semantic interoperability delivered.
