|
Generic abbreviated |
NPU19811 Csf—Immunoglobulin G/Albumin; rel.mass ratio(Csf/P) = ? | |
Full result | NPU19811 Cerebrospinal fluid—Immunoglobulin G/Albumin; relative mass ratio(Cerebrospinal fluid/Plasma) = 0.54 x one | |
Abbreviated result | NPU19811 Csf—Immunoglobulin G/Albumin; rel.mass ratio(Csf/P) = 0.54 | |
Written expression | The relative mass ratio of Immunoglobulin G/Albumin in Mr. Smith’s Cerebrospinal fluid is [0.54]. The calcuation is performed by dividing the mass ratio of Immunoglobulin G/Albumin in Mr. Smith’s Cerebrospinal fluid with mass ratio of Immunoglobulin G/Albumin in Mr. Smith’s plasma. | |
