To understand blood coagulation tests it is helpful to have a basic understanding of the role of the different blood clotting factors and the coagulation.

HEMOSTASIS When blood vessels are cut or damaged, the loss of blood from the system must be stopped before shock and possible death occur. This is accomplished.

HEMOSTASIS A.C.KAROBIA

HEMOSTASIS-definition Arrest of bleeding by: -Normal vasoconstriction -Abnormal obstruction -Coagulation or surgical means.

Disorders of hemostasis -Leads to an increased risk of bleeding (hemorrhage) -Obstructive clotting

Stages of Hemostasis

Secondary Hemostasis cascade Phase 1: Extrinsic and intrinsic pathways produce prothrombinase. Phase 2: Prothrombinase converts prothrombin to thrombin Phase 3: Thrombin converts soluble fibrinogen into insoluble fibrin which is the thread of the clot.

Coagulation screening Basic Screen tests –Platelet count –bleeding time for platelet function –Prothrombin ratio (PR) for extrinsic pathway –Activated Partial Thromboplastin time (Aptt) for the intrinsic pathway –Fibrinogen assay for final common pathway

Coagulation screening specific factor assays - D-dimer - Thrombin time
