I use LOINC for the development of software for ultrasound in Brazil. I recently had a problem regarding the use of some loincs to a model of the patient’s record. For example …
I use LOINC 29463-7 (body weight) in the software, but there are two common units that I can use which are: kilograms and pounds. However, as can identify which unit I will be using, for example, transmission of data in the HL7 standard.
In Brazil we use the body weight in kg, but if it is necessary to export that data to another country, perhaps there is a false interpretation of the information.
Would not it be more correct to have a LOINC for body weight in kg and another for pound?
