Short activated partial thromboplastin times (APTTs) are generally considered to be a surrogate marker of inappropriate blood collections. However, recent evidence suggests that short APTT may reflect a hypercoagulable state, potentially associated with an increased thrombotic risk and adverse cardiovascular events. Earlier studies have showed the proportion of short APTT is about 6%-9% in the hemostasis laboratory. We prospectively computed the rate of short APTT in outpatient, inpatient and emergency (ER) from January to April, 2014, and the proportion were 7.8%, 8.3% and 22.4%, respectively. We assumed that higher proportion in ER might be due to the inappropriate blood collections not more patients in a hypercoagulable state. Through a literature review and in accordance with the ...
