Getting Started with LOINC

Jumpstart your path to LOINCing prowess.



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 share, exchange, or aggregate data health data such as labs, vitals signs, or clinical documents, but it’s like the Tower of Babel out there. Local systems have different ways of identifying the same test or measurement.

The solution

Map your local test codes to a universal standard that every system can understand. Here's 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.

You know, that semantic interoperability mumbo jumbo.



Alright, that sounds good. Let's get started!
