The program is divided into several sections: Tutorials: uses text, colour graphics and animated graphics to teach the morphology and physiological function of platelets, the haemo-static mechanisms: platelet plug formation and coagulation (intrinsic, extrinsic and common pathways) and anti-clotting mechanisms especially fibrinolysis. Methods: uses text and animated graphics to describe the principles and a step-by-step method of each of the major laboratory tests used in producing a haemostatic profile (Bleeding time, Prothrombin Time, Activated Partial Thromboplastin Time (APTT), Thrombin Time). It also includes details of an automated technique using a coagulometer.

In Clinical Cases: the use of the test results in diagnosis is taught using a highly interactive problem-solving approach which requires students to use data from selected clinical case histories to make a diagnosis. For each of five different cases (haemophilia, Disseminated Intravascular Coagulation, von Willebrand Disease, alcohol-induced liver disease, pro-myelocytic leukaemia) a brief patient history and a haemostatic profile is provided. Students must answer on-screen questions and may access relevant further test results. They must then use this information to make a correct diagnosis from a list of possible conditions. Feedback and help are available throughout and there is also a glossary, which explains the medical terms used.
