5902-2 Prothrombin time (PT)

Part Descriptions

LP16870-5   Coagulation tissue factor induced
The prothrombin time (PT) and its derived measures of prothrombin ratio (PR) and international normalized ratio (INR) are measures of the extrinsic pathway of coagulation. They are used to determine the clotting tendency of blood, in the measure of warfarin dosage, liver damage and vitamin K status. The reference range for prothrombin time is usually around 12-15 seconds; the normal range for the INR is 0.8-1.2. It is used in conjunction with the activated partial thromboplastin time (aPTT) which measures the intrinsic pathway. PT is sometimes used as the third screening test in the lupus anticoagulant testing algorithm and is included in the LOINC LA aPTT & dRVVT & PT panel.

6301-6 INR in Platelet poor plasma by Coagulation assay

Part Descriptions

LP17102-2   Coagulation tissue factor induced.INR
The INR is specifically intented for evaluating protime results on patients stabilized on long term oral anticoagulant therapy. The INR is not appropriate to evalulate hemostatic function in patients with liver disease, for screening for hereditary factor deficiencies or acquired vitamin K deficiencies, or for routine preoperative screening; this should be evaluated on the normal range in seconds. INR is calculated by the equation, INR = (PTR) raised to the power of ISI, where ISI = International Sensitivity Index (assigned to each reagent thromboplastin). PTR = prothrombin time ratio (pat PT/pop mean PT). Computation of the INR of specific thromboplastin reagent should allow for uniformity in prothrombin time testing regardless of the reagent system or instrumentation used.

14979-9 aPTT in Platelet poor plasma by Coagulation assay

Part Descriptions

LP15957-1   Coagulation surface induced
Coagulation surface induced (aPTT) is the evaluation of intrinsic coagulation system and is useful in monitoring heparin therapy; aid in screening for the following: presence of classical hemophilia A, and B; Christmas disease; congenital deficiencies of factors II, V, VIII, IX, X, XI, and XII; presence of dysfibrinogenemia; disseminated intravascular coagulation; liver failure;congenital hypofibrinogenemia; vitamin K deficiency; congenital deficiency of Fitzgerald factor; congenital deficiency of prekallikrein; circulatory anticoagulant when heparin is given for treatment or prevention of thromboembolism.

LP15957-1   Coagulation surface induced
The partial thromboplastin time (PTT) or activated partial thromboplastin time (aPTT or APTT) is a performance indicator measuring the efficacy of both the "intrinsic" (now referred to as the contact activation pathway) and the common coagulation pathways. Apart from detecting abnormalities in blood clotting, it is also used to monitor the treatment effects with heparin, a major anticoagulant. It is used in conjunction with the prothrombin time (PT) which measures the extrinsic pathway. Copyright Text is available under the Creative Commons Attribution/Share-Alike License.

3255-7 Fibrinogen [Mass/volume] in Platelet poor plasma by Coagulation assay

Part Descriptions

LP14704-8   Fibrinogen
Fibrinogen is a plasma glycoprotein that was first isolated from horse plasma in 1876. Fibrinogen is produced in the liver and constitutes 5% of the total plasma protein. It is vital to wound healing, fibrinolysis, inflammation, cellular and matrix interactions and neoplasia by interacting with numerous proteins and cells. Fibrinogen activates a series of clotting factors in response to an injury or other stimuli that leads to the enzymatic conversion of soluble fibrinogen into fibrin. Fibrin is the insoluble, structural component of blood clots. Fibrinogen is an acute phase reactant that can increase 200-400% in response to infection, chronic inflammation, smoking and other environmental stresses.
