Definition in words |
Arbitrary amount-of-substance of component B divided by mass of system 1 | ||
Definition by equation |
Note: kprocedure is a constant defined by the measurement procedure (there is an approximately proportionality to a kind-of-quantity from the International System of Quantities). |

Result type |
Rational scale |

|
Unit |
International unit (IU) or procedure defined unit (p.d.u.) (non-SI units) | ||
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. If the ratio scale is attributed to the NPU definition, the unit is a non-SI unit. If the unit is an International Unit (IU), an international certified reference material (e.g. WHO reference material) is specified in the specification to the kind-of-property. If there exist no an international certified reference material, the laboratory can specify the unit at the placeholder, procedure defined unit. |

NPU56149 Pt—Chorionic Gonadotropin(administered); arb.subst.cont.(i.m.; am.s./body mass; IS 07/364; proc.) = ? IU/kg |
Full result | NPU56149 Patient—Chorionic Gonadotropin(administered); arbitrary substance content(intramuscular; arbitrary amount-of-substance/body mass; IS 07/364; procedure) = 108 IU/kg | |
Abbreviated result | NPU56149 Pt—Chorionic Gonadotropin(administered); arb.subst.cont.(i.m.; am.s./body mass; IS 07/364; proc.) = 108 IU/kg | |
Written expression | The arbitrary substance content of administered Chorionic Gonadotropin in Mrs. Smith is [108] IU/kg. The procedure is defined by the laboratory. The substance is administrered intramuscular. “IU” is defined and its magnitude by the certified reference material, IS 07/364 from WHO. | |
