Hi Stuart, Thanks for your answer, In France, information transfer from labs to doctors really sucks. Messages are exchanged in a (not so bad) format (called HPRIM2) in which each test has a "label" and a "code" (plus, of course, a value, a unit, etc). Unfortunately, both the label and the code are filled inconsistently (the code can even be the accounting code for the test in this lab). Of course, asking each and every French lab to change and fill the proper table with the proper codes will not be easy task, but a group of MD seems ready to select the 20% tests used 80% of the time in "usual GP practice" in order to make some buzz about this issue. In a country where the administration is "stupid about health", this could be a good demonstration of what people "in the field" can do when they are really eager to have things change. I know about Loinc... but I also know that it is a huge nomenclature! Maybe finding a subset in Loinc would be fine... or previously selecting the 80/20 lab test exams and, as a second step, using Loinc to code them. Philippe
