A koagulogram, also known as a coagulation profile or clotting test, is a laboratory test used to evaluate the blood's ability to clot. It assesses various components of the coagulation cascade, a complex series of protein interactions that ultimately lead to the formation of a fibrin clot. This test is crucial for diagnosing and monitoring bleeding disorders, thrombotic conditions, and the effectiveness of anticoagulant therapies.

Key parameters typically included in a koagulogram are the prothrombin time (PT), which measures the extrinsic pathway of coagulation, and the activated partial thromboplastin time (aPTT), which assesses the intrinsic pathway. An elevated PT or aPTT suggests a delay in blood clotting, potentially due to deficiencies in clotting factors or the presence of inhibitors. The international normalized ratio (INR) is often reported alongside the PT, standardizing PT results across different laboratories, particularly for patients on warfarin therapy.

Other components may include platelet count, fibrinogen levels, and tests for specific clotting factors or inhibitors like D-dimer, which can indicate the breakdown of clots. Abnormal results in a koagulogram can point to various medical conditions, ranging from hemophilia and von Willebrand disease to liver disease and disseminated intravascular coagulation (DIC). Healthcare professionals interpret the koagulogram in conjunction with a patient's medical history, symptoms, and other diagnostic findings to make informed treatment decisions. Regular monitoring of koagulogram parameters is essential for individuals undergoing anticoagulant treatment to ensure therapeutic efficacy and minimize the risk of bleeding or clotting complications.
