What is a normal prothrombin time (PT)? PT is a

comparative test that measures the client’s PT to

the control time. Both the PT and control time

results are reported. One example of the use of a

PT is to measure the effectiveness of prescribed

anticoagulant therapy. In this case, the therapeutic

range is 2 to 2.5 times the control time, which is 12

to 14 seconds. If the control time is 12 seconds,

what would you expect the client’s PT to be?
