Extraction method for preparing thromboplastin reagents |
| abstract |
The Prothrombin Time (PT) is used as a screening test for blood coagulation factor deficiencies and for monitoring oral anti-coagulant therapy using coumadin. Thromboplastin reagents activate the extrinsic pathway of coagulation and are the basis for the Prothrombin Time (PT) test. This invention describes the use of barium sulfate and chaotropic agents, and nonionic detergents, for the extraction of sensitive thromboplastin reagents from tissue. Extraction with sodium thiocyanate alone also greatly enhances thromboplastin sensitivity. This invention should be useful for all thromboplastins and will improve their sensitivity for all PT-based tests and specific assays. |
