A clotting screen is a blood test that checks how well your blood clots. It helps identify bleeding disorders, monitor clotting problems, and assess risks before surgery. If you are experiencing unusual bleeding, frequent bruising, or have a family history of clotting issues, a clotting screen is usually recommended.
A clotting screen checks how well blood clots and helps detect bleeding or clotting disorders. It is recommended for those with frequent nosebleeds, heavy periods, easy bruising, or a history of blood clots or miscarriages.
The test is also done before surgery to prevent excessive bleeding and is used to monitor blood-thinning medications. Since the liver produces clotting factors, the test can help assess liver health. It also detects autoimmune or genetic conditions like lupus anticoagulant syndrome or Factor V Leiden, which increase clotting risks.
A clotting screen can help spot conditions that affect how your blood clots, such as haemophilia, Von Willebrand Disease, Factor V Leiden Mutation, and Disseminated Intravascular Coagulation (DIC). Haemophilia is a genetic condition that causes excessive bleeding and affects about 1 in 10,000 people worldwide. Von Willebrand Disease is much more common, affecting around 80 million people globally, and happens when the blood lacks a key protein needed for clotting.
Factor V Leiden Mutation makes blood more likely to clot and is found in 3 to 8% of people of European descent, meaning millions worldwide have a higher risk of blood clots. DIC, on the other hand, is a serious condition linked to infections or trauma, where the body forms too many clots and then struggles to stop bleeding when needed. A clotting screen can help detect these issues early, making it easier to manage and treat them before they become serious.
Normal results mean your blood is clotting as it should. Prolonged clotting times may suggest a bleeding disorder, while shortened clotting times could indicate a higher risk of blood clots. Abnormal INR levels may require changes to your anticoagulant medication.
Individuals at higher risk for clotting disorders (in the UK and around the world) include:
