Why the study?
Do various blood coagulation tests correlate with each other and reliably detect hypercoagulability or predict thrombophlebitis in postoperative and congestive heart failure patients?
Do various blood coagulation tests correlate with each other and reliably detect hypercoagulability or predict thrombophlebitis in postoperative and congestive heart failure patients?
Multiple blood coagulation tests show poor correlation with one another and do not reliably predict the development of clinical thrombophlebitis in postoperative or heart failure patients.
Answers are grounded in this paper and cite their sources.
Coagulation tests should not yet inform thrombophlebitis risk in postoperative patients; leaves open validation of reliable hypercoagulability markers.
In recent years a number of tests have been de- signed for the purpose of detection of accelerated blood coagulation. Among these are the lusteroid tube coagulation test (1-4), the silicone tube co- agulation test (5), the modified clot retraction test (6), the modified Lee-White clotting test, employ- ing three test tubes instead of one (7), the heparin retarded coagulation test of Waugh and Ruddick (8, 9), the heparin tolerance test ( 10, 11 ), and the prothrombin time determination, using both whole and dilute plasma (12-14).
