| | Coagulation - |
 | | The coagulation cascade of secondary hemostasis has two pathways, the Contact Activation pathway (formally known as the Intrinsic Pathway) and the Tissue Factor pathway (formally known as the Extrinsic pathway) that lead to fibrin formation. | | | It was previously thought that the coagulation cascade consisted of two pathways of equal importance joined to a common pathway. | | | Tissue Factor pathway: the main role of the tissue factor pathway is to generate a "thrombin burst". |

| | Although the concept of "intrinsic" and "extrinsic" pathways served for many years as a useful model for coagulation, more recent evidence has shown that the pathways are not, in fact, redundant but are highly interconnected. | | | Coagulation can be initiated via the "intrinsic" pathway in vitro | | | Prolongation of both the aPTT and the PT suggests that the defect lies in a common pathway. |

| | Coagulation Testing (Part 1): Current Methods and Challenges (IVDT archive, Jul 98) |
| | Whether the tests are performed in the central coagulation laboratory or in a near-patient setting (at the patient's bedside or in the patient's home after hospital discharge), they all aim to characterize the functioning of the patient's coagulation system so that the clinician can make appropriate decisions for therapeutic intervention. | | | APTT is used to assess the overall competence of a patient's coagulation system, as a preoperative screening test for bleeding tendencies, and as a routine test for monitoring heparin therapy. | | | The PT test can provide an assessment of the extrinsic coagulation pathway, and is widely used to monitor oral anticoagulation therapy. |
