The book "Platelet Response to Aspirin with Platelet Aggregation Methods" offers a comprehensive analysis of the response of platelets to aspirin, one of the most commonly prescribed medications for thrombosis prevention. It highlights the challenges associated with treating patients who exhibit aspirin resistance. The authors Wan Zaidah Abdullah, Sanada Abu Bakar, and Rosline Hassan present various methods for assessing platelet response to aspirin, focusing on the application of whole blood platelet aggregation. This method proves to be less cumbersome compared to the use of platelet-rich plasma. The book is a valuable resource for professionals in clinical diagnostics, particularly for pathologists, hematologists, and laboratory technologists involved in coagulation and hemostasis testing. The clear comparisons of methods and the reliability of the results make it an indispensable reference work in this specialized field.
