Description

Fibrinopeptide A: Two small peptide chains removed from the N-terminal segment of the alpha chains of fibrinogen by the action of thrombin during the blood coagulation process. Each peptide chain contains 18 amino acid residues. In vivo, fibrinopeptide A is used as a marker to determine the rate of conversion of fibrinogen to fibrin by thrombin.

Overview

Fibrinopeptide A (FPA) is a plasma peptide, formed by the action of thrombin on fibrinogen during clog formation. High concentration of FPA in blood occurs in patients with ischemic heart disease.

Effects

Fibrinopeptide A (FPA) levels have been followed sequentially in a three-year study of 50 patients with advanced carcinoma. FPA levels were assayed in 10 normal subjects using a radioimmunoassay (RIA-mat FPA Mallinckrodt)
