Question

Which of the following is a point of care test (POCT) used in diagnosing problems with hemostatis?

1) Prothrombin Time (PT)
2) Activated Partial Thromboplastin Time (aPTT)
3) International Normalized Ratio (INR)
4) All of the above

Answer 1

The point of care tests used for diagnosing hemostasis problems include Prothrombin Time (PT), Activated Partial Thromboplastin Time (aPTT), and International Normalized Ratio (INR), thus the correct answer is all of the above.

Step-by-step explanation:

The point of care tests (POCT) used in diagnosing hemostasis issues include Prothrombin Time (PT), Activated Partial Thromboplastin Time (aPTT), and International Normalized Ratio (INR). Each of these tests assess different pathways and factors involved in the clotting process. The liver plays a crucial role in the production of coagulation factors, and these tests help in evaluating the functionality of the coagulation pathways.

• Prothrombin Time (PT): Measures the time it takes for blood to clot by assessing the extrinsic and common pathways.
• Activated Partial Thromboplastin Time (aPTT): Evaluates the intrinsic and common pathways.
• International Normalized Ratio (INR): Standardized version of PT, used especially to monitor the effectiveness of anticoagulant therapy.

Therefore, the correct answer to which POCTs are used in diagnosing problems with hemostasis is all of the above.
