Common LOINC Result and Universal Order Codes



Get LOINCing fast.

We know you want to hit the ground running, so we’ve created a few lists that help focus on some low hanging fruit. With help from the LOINC community, we’ve compiled three data-driven lists to jump start your standardization effort: a list of the most common result codes and mapping advice to go with it, a collection of frequently used universal order codes, and a starter set of UCUM codes (for those of you brave enough to standardize your units of measure).


You can get them all right here.
