I run the same analyte on two different vendors analzers, which LOINC code do I use?
The LOINC code may be the same for multiple analyzers due to similar methodologies or it may be different. If the analyte is reported out using the same units with both instruments and the reference ranges are the same, they may have the same LOINC code, unless the method makes a difference to the report. If the method makes a difference, you should use that method specific LOINC code. If one does not exist, you should request a new term (see proposing new terms below).
