Definition: permits the producer to record results-dependent codes for classifying the observation at the receiving system. This field should be needed only rarely, because most classifications are fixed attributes of the observation ID and can be defined in the associated observation master file (see description in section 7.1).
However, there are a few cases when such controls vary with the value of the observation in a complex way that the receiving system would not want to re-calculate. An example is an antimicrobial sensitivity result. Some systems prefer to display only the sensitivity results of inexpensive antibiotics depending upon the organism, the source of the specimen and the patients allergy status. The sending service wants to send all of the sensitivities so that certain privileged users (e.g., Infectious Disease specialists) can review all of the results but nonprivileged users would see only the "preferred" antibiotics to which the organism was sensitive. We expect that other cases also occur.
