Question

What is the normal bleeding time and clotting time?

Answer 1

Answer:

The expected range for clotting time is 4-10 mins. This test measures the time taken for blood vessel constriction and platelet plug formation to occur. No clot is allowed to form, so that the arrest of bleeding depends exclusively on blood vessel constriction and platelet action.

Answer 2

Answer:

The normal bleeding time is between 2-7 minutes. The normal clotting time in a person is between 8-15 minutes. By understanding the time taken for blood to clot, it can be determined if the person has haemophilia or von Willibrand's disease.
