Definition in words |
Time of component B in system 2 divided by time of component in system 1 Note 1: System 1 is unrelated to system 2 Note 2: System 2 can be a reference system (also called “norm”) that is defined by the laboratory |

Example 1 | |
Generic abbreviated |
NPU01680 P—Coagulation, surface-induced; recip.rel.time(norm/actual; proc.) = ? | |
Full result | NPU01680 Plasma—Coagulation, surface-induced; reciprocal relative time(norm/actual; procedure) = 1.25 x one | |
Abbreviated result | NPU01680 P—Coagulation, surface-induced; recip.rel.time(norm/actual; proc.) = 1.25 | |
Written expression | The reciprocal relative time of surface-induced Coagulation in Mr. Smith’s plasma is [1.25]. The calculation is performed by dividing the time of surface-induced Coagulation in a norm (reference system) with the time of surface-induced Coagulation in Mr. Smith’s plasma. The measurement is performed according to procedure defined by the laboratory. | |

Generic abbreviated |
NPU27548 P—Coagulation, tissue factor-induced; recip.rel.time(norm/actual; II+V+VII+X; proc.) = ? | |
Full result | NPU27548 Plasma—Coagulation, tissue factor-induced; reciprocal relative time(norm/actual; II+V+VII+X; procedure) = 1.11 x one | |
Abbreviated result | NPU27548 P—Coagulation, tissue factor-induced; recip.rel.time(norm/actual; II+V+VII+X; proc.) = 1.11 | |
Written expression | The reciprocal relative time of tissue factor-induced Coagulation in Mr. Smith’s plasma is [1.11]. The calculation is performed by dividing the time of tissue factor-induced Coagulation in a norm (reference system) with the time of tissue factor-induced Coagulation in Mr. Smith’s plasma. The measurement is performed according to procedure defined by the laboratory. | |
