What is the typical normal value range for Partial Prothrombin Time (PTT)?

• A. 30-40 seconds
• B. 60-70 seconds
• C. 75-90 seconds
• D. 100-120 seconds

Answer: (A)

The typical normal value range for Partial Prothrombin Time (PTT) is indeed around 30-40 seconds. PTT is a laboratory test that measures the time it takes for blood to clot, specifically assessing the intrinsic and common pathways of coagulation. This value can vary slightly based on the specific testing protocols used in different laboratories, but a range of 30 to 40 seconds is widely accepted for healthy individuals. When clotting factors are functioning normally, the PTT results will typically fall within this range. Elevated PTT values may indicate various conditions, including the presence of anticoagulants, specific bleeding disorders, or liver disease, highlighting the importance of maintaining the value within the normal range for effective hemostasis.
