Arbitrary rate (arb.rate)
Abbreviation |
Arb.rate | ||
---|---|---|---|
Definition in words |
Arbitrary rate of component B in system 1 compared with arbitrary rate 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 | NPU17681 Cns—Immunoglobulin M production; arb.rate(proc.) = ? | |
Full form with a result | NPU17681 Central nervous system—Immunoglobulin M production; arbitrary rate(procedure) = very high | |
Abbreviated form with a result | NPU17681 Cns—Immunoglobulin M production; arb.rate(proc.) = very high | |
Written expression | The arbitrary rate of Immunoglobulin M production in Mr Smith’s central nervous system is [very high] compared to the arbitrary rate of Immunoglobulin M production 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. “Very high” is a value according to a value set defined by the laboratory. |
|
Example 2 | ||
Generic abbreviated form | NPU17680 Cns—Immunoglobulin A production; arb.rate(proc.) = ? | |
Full form with a result | NPU17680 Central nervous system—Immunoglobulin A production; arbitrary rate(procedure) = 2 | |
Abbreviated form with a result | NPU17680 Cns—Immunoglobulin A production; arb.rate(proc.) = 2 | |
Written expression | The arbitrary rate of Immunoglobulin A production in Mr Smith’s central nervous system is [2] compared to the arbitrary rate of Immunoglobulin A production 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. “2” is a value according to a value set defined by the laboratory. |
|
Clinical Microbiology | Example 3 | |
Generic abbreviated form |
NPU56150 Csf—Borrelia antibody production; arb.rate(proc.) = ? | |
Full form with a result | NPU56150 Cerebro spinal fluid—Borrelia antibody production; arbitrary rate(procedure) = none | |
Abbreviated form with a result | NPU56150 Csf—Borrelia antibody production; arb.rate(proc.) = none | |
Written expression | The arbitrary rate of Borrelia antibody production in Mr Smith’s central nervous system is [none] compared to the arbitrary rate of Borrelia antibody production 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. |
|
Example 4 | ||
Generic abbreviated form | NPU29229 T-lymcs(B)—Interferon gamma release(TB-related); arb.rate(proc.) = ? | |
Full form with a result | NPU29229 T-lymphocytes(Blood)—Interferon gamma release(Tuberculosis-related); arbitrary rate(procedure) = + | |
Abbreviated form with a result | NPU29229 T-lymcs(B)—Interferon gamma release(TB-related); arb.rate(proc.) = + | |
Written expression | The arbitrary rate of Tuberculosis-related Interferon gamma release in Mr Smith’s central nervous system is [+] compared to the arbitrary rate of Tuberculosis-related Interferon gamma release 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. |
