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.
