ACTIVATED COAGULATION TIME WHOLE BLOOD Meaning and
Definition
-
Activated Coagulation Time Whole Blood refers to a laboratory test that measures the time it takes for blood to form a clot. It is used to assess the integrity and functionality of the clotting system in the body.
When a blood vessel is damaged, certain substances are released that initiate a series of chemical reactions known as the coagulation cascade. This cascade ultimately leads to the formation of a blood clot, which helps to seal the damaged blood vessel and prevent excessive bleeding.
The activated coagulation time test measures the time it takes for blood to clot after a specific activating substance called activator is added to the blood sample. The activator triggers the coagulation cascade, allowing the measurement of the clotting time.
Typically, a small amount of whole blood is taken from the patient and mixed with the activator in a specialized laboratory tube. The time taken for the blood to clot is measured precisely. This test is primarily used during invasive procedures, such as cardiovascular surgeries or interventions, to monitor the patient's clotting ability and assess the efficacy of any anticoagulant medications being administered.
The activated coagulation time whole blood test is an important diagnostic tool to evaluate clotting disorders, determine hemorrhagic risks, and guide treatment decisions, especially for patients on anticoagulant therapies or with suspected coagulation abnormalities.
