About test
What does ACTIVATED PARTIAL THROMBOPLASTIN TIME (APTT) measure?
Activated Partial Thromboplastin Time (APTT) is a blood clotting test that evaluates how long it takes blood to form a clot through part of the coagulation pathway. It may be used to investigate unexplained bleeding or clotting, assess certain clotting factor deficiencies, or monitor treatment with unfractionated heparin. Results are interpreted alongside medical history, other coagulation tests, and any medicines being taken.
