In normal full-term newborns and in healthy premature infants (30-36 weeks gestation), fibrinogen is near adult levels (>150) and remains at adult levels throughout childhood.

Method Description

The PT Fibrinogen assay is performed using the HemosIL PT-Fibrinogen kit on the Instrumentation Laboratory ACL TOP. Prothrombin Time (PT) thromboplastin reagent is added to patient plasma; endogenous thrombin from the patient’s plasma is generated during the reaction and converts fibrinogen to fibrin. This change from fibrinogen to fibrin is monitored by the instrument through reading the light absorbance over a set amount of time. At the end of the allotted time, the instrument uses a set algorithm to determine the delta and plot it against the calibration curve. The delta value is directly proportional to the amount of fibrinogen in the sample.(Package insert: HemosIL PT Fibrinogen. Instrumentation Laboratory Company; 01/2016)
