Interpretation of Results of Routine and Special Coagulation Tests

Physicians typically have limited knowledge about the laboratory tests which most effectively work-up a patient presenting with bleeding or clotting manifestations; which tests best evaluate the efficacy of antithrombotic agents; and the clinically significant impact of anticoagulant agents on routine and special coagulation assay results. This practical guide will help physicians to appropriately order and interpret coagulation tests to identify the underlying hemostasis disorder or develop a timely action plan for the benefit of their patient. Interpretation of Results of Routine and Special Coagulation Tests: A Practical Guide is a concise, comprehensive, and accessible reference text for any medical professional who must order, understand, or interpret tests of the hemostasis system. For each test, this book provides the causes of abnormal results, including what can lead to false positive and negative results. When possible, information is provided in table form for quick reference, such as the impact of commonly used anticoagulants on the results of hemostasis tests. This practical guide also includes tests that evaluate global hemostasis and clot lysis by viscoelastometry, as well as a discussion of laboratory monitoring of anticoagulants, antiplatelet agents, antifibrinolytics, and thrombolytics. Written by an expert author team, this easy-to-use guide will be a vital resource for residents, fellows, and practitioners.
