Clotting Check Blood Test

About this test

Some conditions can prevent blood from clotting properly, may cause the blood to clot too easily or cause clots to remain in the body for too long. Clotting (or coagulation) tests are often used to monitor patients taking anticoagulants - medications that decrease the ability of the blood to clot.

Anticoagulant medications are often prescribed to patients after they have suffered a heart attack or stroke. Those with arrhythmia (an irregular heart beat) may also take anticoagulants to prevent a first or recurrent stroke.

This test evaluates the clotting tendency of blood and the time it takes for clots to form using the standard measures of prothrombin time (PT), APTT and the International Normalised Ratio (INR) which is derived from PT. These tests can reveal if clotting factors are low or absent and can help to identify which ones. INR is typically used to help inform dosage for patients taking anticoagulants (commonly warfarin) and to monitor progress over time.

Fibrinogen is a protein that aids in the formation of blood clots. Low levels of fibrinogen are sometimes seen in cases of excessive clotting, such as disseminated intravascular coagulation (DIC).
