NPU18995 P—Plasma; rel.visc.(37 °C/water, 37 °C) = ? |
Full result | NPU18995 Plasma—Plasma; relative viscosity(37 °C/water, 37 °C) = 2.5 x one | |
Abbreviated result | NPU18995 P—Plasma; rel.visc.(37 °C/water, 37 °C) = 2.5 | |
Written expression | The relative viscosity of Mr. Smith Plasma is [2.5]. The calculation is performed by dividing the viscosity of Mrs. Smith’s Plasma with the viscosity of water. The measurements in plasma and water are performed at 37 °C. | |
