Arbitrary content (arb.cont.)
Abbreviation |
Arb.cont. | ||
---|---|---|---|
Definition in words |
Arbitrary content of component B in system 1 compared with arbitrary content of component B in a reference system. Note 1: The reference system is defined by the laboratory. Note 2: Content refers to mass of system 1 or a system 1 in solid state. |

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 |
|
---|---|---|
Clinical Chemistry | Example 1 | |
Generic abbreviated form | NPU01393 F—Haemoglobin; arb.cont.(proc.) = ? | |
Full form with a result | NPU01393 Faeces—Haemoglobin; arbitrary content(procedure) = + | |
Abbreviated form with a result | NPU01393 F—Haemoglobin; arb.cont.(proc.) = + | |
Written expression | The arbitrary content of Haemoglobin in Mr. Smith’s Faeces is [+], compared with arbitrary content of Haemoglobin in a reference system. The measurement is performed according to a procedure defined by the laboratory, | |
Notes |
The reference system is defined by the laboratory. “+” is a value according to a value set defined by the laboratory. |
|
Clinical Microbiology | Example 2 | |
Generic abbreviated form | NPU12110 F—Coxsackievirus; arb.cont.(proc.) = ? | |
Full form with a result | NPU12110 Faeces—Coxsackievirus; arbitrary content(procedure) = none | |
Abbreviated form with a result | NPU12110 F—Coxsackievirus; arb.cont.(proc.) = none | |
Written expression | The arbitrary content of Coxsackievirus in Mr. Smith’s Faeces is [none], compared with arbitrary content of Coxsackievirus in a reference system. The measurement is performed according to a procedure defined by the laboratory, | |
Notes |
The reference system is defined by the laboratory. “None” is a value according to a value set defined by the laboratory. |

Clinical Toxicology |
Example 3
|
|
Generic abbreviated form | NPU53461 Hair—Cocaine; arb.cont.(proc.) = ? | |
Full form with a result | NPU53461 Hair—Cocaine; arbitrary content(procedure) = negative | |
Abbreviated form with a result | NPU53461 Hair—Cocaine; arb.cont.(proc.) = negative | |
Written expression | The arbitrary content of Cocaine in Mr. Smith’s hair is [negative], compared with arbitrary content of Cocaine in a reference system. The measurement is performed according to a procedure defined by the laboratory, | |
Notes |
The reference system is defined by the laboratory. “Negative” is a value according to a value set defined by the laboratory. |
|
Molecular Biology and Genetics | Example 4 | |
Generic abbreviated form | NPU27386 DNA(P)—RHD gene; arb.cont.(proc.) = ? | |
Full form with a result | NPU27386 DNA(Plasma)—RHD gene; arbitrary content(procedure) = 1 | |
Abbreviated form with a result | NPU27386 DNA(P)—RHD gene; arb.cont.(proc.) = 1 | |
Written expression | The arbitrary content of RHD gene of DNA in Mrs. Smith’s Plasma is [1], compared with arbitrary content of RHD gene of DNA in a reference system. The measurement is performed according to a procedure defined by the laboratory, | |
Notes |
The reference system is defined by the laboratory. “1” is a value according to a value set defined by the laboratory. |

Date | Notes | Example |
---|---|---|
2019-03-19 | Arbitrary content should, in principle, only be used for NPU codes that describe an examination in solid patient system (e.g. hair, skin etc.). Patient system that has been exposed for sample treatment is no longer a patient system but some kind of a sample. The sample can be a fluid system but the result should be converted according to a solid patient system.. |
