Problems with the body's clotting system cause either excessive bleeding or dangerous clotting (thrombosis). Coagulation tests precisely measure the blood's clotting ability — essential before surgery, for patients on blood thinners, and when investigating unexplained bleeding.
Comprehensive assessment of the bleeding and clotting system.
Measures clotting via the extrinsic pathway. INR standardises the result across laboratories. Essential for monitoring warfarin therapy and investigating unexplained bleeding or liver disease.
Measures clotting via the intrinsic pathway. Used in haemophilia A and B investigation and for monitoring heparin anticoagulation therapy.
Basic screening tests for overall haemostatic function. Often ordered as part of pre-operative assessment.
Breakdown product of blood clots. Elevated in deep vein thrombosis (DVT), pulmonary embolism (PE), and DIC. A normal D-dimer effectively rules out active clotting in most clinical scenarios.
Measures the main clotting protein. Important in DIC (Disseminated Intravascular Coagulation), liver disease, and post-surgical monitoring.
Assesses how well platelets function — relevant when platelet count is normal but bleeding symptoms are present.
Bleeding risk assessment is standard before any procedure. PT, APTT, and platelet count are the minimum pre-operative screen
Warfarin requires regular INR monitoring to maintain the therapeutic range. Too low: clotting risk. Too high: bleeding risk
D-dimer is the first-line test when a blood clot in the leg or lung is suspected. A normal result makes active clotting very unlikely
Heavy periods, frequent nosebleeds, or easy bruising may indicate a clotting or platelet disorder — warranting full coagulation screen
