The Activated Coagulation Time (ACT) test is a medical procedure used to measure the time it takes for blood to clot. It assesses the effectiveness of the coagulation cascade, a series of reactions that form blood clots.
Why is the ACT test important?
The ACT test is crucial in various medical settings, such as surgery and cardiopulmonary bypass procedures, to ensure patients' blood clots within a specific timeframe, preventing excessive bleeding or clot formation.
How is the ACT test performed?
During the ACT test, a blood sample is collected and mixed with an activator, usually kaolin or celite. The time it takes for the blood to clot is measured, typically using a coagulation analyzer.
What do the results of the ACT test mean?
The results represent the time, in seconds, it takes for blood to clot. Longer ACT times indicate delayed clot formation, which can lead to bleeding issues, while shorter times suggest a higher risk of clotting.
