Description

This codelist is used to identify INR blood tests that are explicitly considered to be high.

Methodology

This codelist was developed using OpenCodelists CTV3 definition builder. Term searches included

  • International normalised ratio
  • INR raised

This codelist only contains codes where INR may be considered explicitly raised and does not include codes where INR may be outside range but not clear whether it is high or low for example International normalised ratio deviation from target(XaJel).

This codelist should be combined with INR result values to identify high INRs.
