The abbreviation ACT is defined as which word or phrase?

• A. Anticoagulation therapy
• B. Activated clotting time
• C. Act
• D. To do

Answer: (D)

Activated clotting time is what ACT stands for. It’s a bedside test that measures how long it takes for whole blood to clot after an activator is added, mainly used to monitor the level of anticoagulation (such as heparin) during procedures. This helps clinicians gauge whether the blood is sufficiently anticoagulated for the task at hand. The option you might be thinking of, like “anticoagulation therapy,” refers to treatment, not the test itself, and words like “Act” or “To do” aren’t definitions of this medical abbreviation.
