Activated clotting time (ACT) testing is a point-of-care blood test that measures the time required for whole blood to clot after activation, primarily used to monitor high-dose heparin anticoagulation during procedures involving cardiopulmonary bypass. It provides rapid results, typically within minutes, making it indispensable in perioperative settings for adjusting anticoagulant therapy and preventing thrombosis or excessive bleeding. Devices range from portable point-of-care analyzers to clinical laboratory systems, employing technologies like optical, mechanical, laser, or fluorescent detection. ACT is crucial in cardiovascular surgeries, extracorporeal membrane oxygenation (ECMO), cardiac catheterization, hemodialysis, and critical care, ensuring patient safety amid heparin use.

Market Overview

According to Data Bridge Market Research, the global activated clotting time testing market was valued at USD 489.77 million in 2024 and is projected to reach USD 701.85 million by 2032, growing at a CAGR of 4.60% during the forecast period of 2025–2032.
