Which of the following tests is used to assess coagulation?

Explanation:
Coagulation is assessed by tests that measure how long it takes for plasma to clot. The partial thromboplastin time specifically targets the intrinsic and common pathways of the coagulation cascade, giving a direct readout of how well the coagulation factors are working. A prolonged PTT can indicate deficiencies in factors VIII, IX, XI, or XII, or the presence of inhibitors, and it’s also used to monitor heparin therapy. In contrast, a basic metabolic panel and BUN focus on chemical aspects of the blood like electrolytes and kidney function, not the clotting pathways, and a CBC looks at blood cells, including platelets, but does not measure the time to clot. So the test used to assess coagulation is the partial thromboplastin time.
