Special rule(s) in the NPU syntax |
“List” is stated in the specification to the kind-of-property in the NPU definition. “Procedure” is stated in the specification to the kind-of-property in the NPU definition. “Procedure” indicates that the measurement procedure must be stated somewhere else than the NPU code and there may be difficulties in comparing values for the same NPU code. “?” (placeholder for result) is omitted. |

2019-09-20 | Concentration has only be limited to list codes, in order to specify whether the system is a liquid system. List codes are headers that describe the property of the patient with a list of measurements (one or more NPU codes). The kinds-of-quantity to the NPU codes may be a mix of kinds-of-quantity, e.g. mass concentration, substance concentration, catalytic concentration, arbitrary concentration etc. | |
