A practical guide to laboratory diagnosis and treatment of hemostatic disorders. This concise book covers all you need to know to manage thrombotic and bleeding disorders, distilling the most clinically up-to-date information, and including the latest treatment strategies for key conditions and diseases. Essential Guide to Blood Coagulation covers both the stable and the acute stages of hereditary and acquired bleeding and thrombotic disorders. Faced with a bleeding patient, it may be difficult to determine whether blood loss is due to a local factor or an underlying hemostatic defect. There are a range of laboratory tests which can be performed to identify the cause of bleeding in a patient. This book highlights the tests that can be used in the laboratory to aid diagnosis. Originally published in Swedish, Essential Guide to Blood Coagulation , has been revised to include the latest treatment strategies available for patients and will help clinicians to expand their knowledge of hemostatic disorders .
