Assay Type

Control Plasmas and Calibrators


Fibrinogen Reference Plasma

Intended Use

FIB Calibrator is intended for use as a normal reference standard for routine fibrinogen quantitation on citrated plasma.


FIB Calibrator may be used to generate a standard reference curve for fibrinogen determination or as a quality control check for stored reference curves in daily fibrinogen testing

Principle of the Test


Fresh pooled normal plasma or assayed reference normal plasma is necessary to construct the standard curve(s) in assay(s) that quantify the activity of coagulation factor(s) in patient plasmas. Fib Calibrator can be used to construct the standard curves of fibrinogen assays.

Fib Calibrator is used in fibrinogen assays in the same manner as fresh plasma.
