Special rule(s) in the NPU syntax |
“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. |

Examples |
|
---|---|---|
Allergology | Generic abbreviated form | NPU01115 Trcs(B)—Aggregation, thrombin-induced; arb.threshold c.(proc.) = ? |
Full form with a result | NPU01115 Thrombocytes(Blood)—Aggregation, thrombin-induced; arbitrary threshold concentration(procedure) = Low | |
Abbreviated form with a result | NPU01115 Trcs(B)—Aggregation, thrombin-induced; arb.threshold c.(proc.) = Low | |
Written expression | The arbitrary threshold concentration of Aggregation, thrombin-induced of thrombocytes in Mr. Smith’s blood is [low], compared with arbitrary threshold concentration of Aggregation, thrombin-induced of thrombocytes in a reference system. The measurement is performed according to procedure defined by the laboratory. | |
Notes |
The reference system is defined by the laboratory. “Low” is a value according to a value set defined by the laboratory. |
