Example 1 | |
Generic abbreviated |
NPU03694 Pt—Urine; rel.volumic mass(20 °C/water, 20 °C; proc.) = ? | |
Full result | NPU03694 Patient—Urine; relative volumic mass(20 °C/water, 20 °C; procedure) = 1.18 x one | |
Abbreviated result | NPU03694 Pt—Urine; rel.volumic mass(20 °C/water, 20 °C; proc.) = 1.18 | |
Written expression | The relative volumic mass of Mr. Smith’s Urine is [1.18]. The calculation is performed by dividing the volumic mass of Mr. Smith’s Urine with the volumic mass of water. The measurements in urine and water are performed at 20 °C according to procedure defined by the laboratory. | |
