A comparison study of routine coagulation screening tests (PT and APTT) by three automated coagulation analyzers

Background: In recent times, growing coagulation test volume and constricted personnel budgets have enhanced interest in automated coagulation analyzers. Objective: (i) To compare the reliability of routine coagulation test [prothrombin time (PT) and activated partial thromboplastin time (APTT)] using mechanical, photo-optical, and nephelemetric methods by three automated coagulation analyzers. (ii) To evaluate the performance of a newly...
