# Lab Test Short Name for International Normalized Ratio

Use this text field to specify the Test Short Name (LBTESTCD) value that corresponds to the International Normalized Ratio (INR).

By default, attempts to detect common recommended values for the INR. If it finds one, the report automatically enters it in the text box. If an alternative designation is used in your study, the field is left blank and you must specify the designation.

Note: INR is different from the standard Prothrombin Time test in that INR is the ratio of the observed prothrombin time to a control value.
