Example 4 | |
Generic abbreviated |
NPU29007 P—Fibrinogen; subst.ratio(coag./imm.; proc.) = ? | |
Full result | NPU29007 Plasma—Fibrinogen; substance ratio(coagulation/immunological; procedure) = 0.86 × one | |
Abbreviated result | NPU29007 P—Fibrinogen; subst.ratio(coag./imm.; proc.) = 0.86 | |
Written expression | The substance ratio of Fibrinogen(coagulation)/Fibrinogen(immunological) in Mr. Smith’s plasma is [0.86].The measurement is performed according to a procedure defined by the laboratory. The calculation was performed by division of the quantity of fibrinogen measured by a coagulation procedure divided by the quantity of fibrinogen measured by a immunological procedure. | |
