Factor XIII is a transglutaminase that circulates in the human blood as a heterotetramer of two A and two B subunits. XIIIs bind to the clot via their B units. In the presence of fibrins, thrombin efficiently cleaves the R 37– G 38 peptide bond of each A unit within a XIII tetramer. A units release their N-terminal activation peptides.

Normal factor XIII activity is between 53% and 221%. Immunologic assays of protein – There are tests that involve identifying the exact amount of the A- and B- proteins, and in their absence whether the patient with congenital factor XIII deficiency is missing the A- or B- part of factor XIII.

Coagulation factor XIII (FXIII) is converted by thrombin and Ca 2+ into an active transglutaminase (FXIIIa) in the final phase of coagulation cascade. Its main function is the mechanical stabilization of fibrin clot and its protection from fibrinolysis by cross-linking of fibrin chains and α 2 -plasmin inhibitor to fibrin. In non-substituted patients FXIII deficiency is a severe hemorrhagic

Interferences: No interference from heparin, ammonia, 2021-04-09 · Factor XIII Activity test is recommended by the doctors in order to detect homozygous, heterozygous along with deficiency or decreased levels of Factor XIII (FXIII). This test also indicates those patients who have a genetic bleeding disorder which is caused due to factor xiii deficiency. Blood coagulation factor XIII (FXIII), also known as fibrin stabilizing factor, is a transglutaminase precursor that acts at the final stage of the blood coagulation Factor XIII (13) Activity – Quantitative: 1 week: No: citrated plasma: Fibrinogen Activity: 24 hours: No: citrated plasma: Fibrinogen Antigen: 1 week: No: citrated plasma: Fondaparinux (Arixtra) Level: 24 hours: No: citrated plasma: Dabigatran (Pradaxa) Level: 24 hours: No: citrated plasma: Euglobulin Clot Lysis Time: 1 week: No: citrated plasma: Factor II (2) Activity: 24 hours: No: citrated plasma Factor XIII is a transglutaminase, which is important in the cross-linking of the fibrin framework of the clot.

The activated Factor XIII (XIIIa) acts on fibrin (Factor Ia) to form γ-glutamyl-Є-lysyl amide cross links between fibrin molecules leading to the formation of an insoluble clot. 2021-03-09 Factor XIII Activity 69-143%.

Materials provided: Preferred first-line test to diagnose inherited or acquired factor XIII (FXIII) deficiency. Appropriate for evaluation of patients with a bleeding disorder who present with normal prothrombin time (PT), activated partial thromboplastin time (aPTT), and platelet count test results. BIOPHEN™ Factor XIII kit is a chromogenic method proposed for in vitro quantitative determination of Factor XIII activity in human citrated plasma. SUMMARY AND EXPLANATION: Factor XIII (FXIII) protransglutaminase circulates in plasma as A 2 B 2 tetramer, the A subunit being the functional form.
