About

Description

This codelist was developed to identify patients receiving a alanine transferaminase test, as an indicator of a liver function test.

Methodology

We searched SNOMED CT for "alanine aminotransferase" and selected all codes with reference to the test measurement or level.

Codelists are developed by a broad community of users for individual study purposes, which may or may not meet the needs of other studies. They should not be thought of as universal definitions of a particular condition.

We don't offer any guarantees about what they do or don't identify. Users should carefully check that any codelist meets their needs, and seek clinical input where appropriate.

Codes not in the full codelist are in faint grey.
