Unsuitability of evacuated tubes for monitoring heparin therapy by activated partial thromboplastin time.
Activated partial thromboplastin times (APTT) for monitoring heparin therapy for venous thromboembolism tended to be inappropriately short if blood was collected in commercially available evacuated glass tubes. Five types of evacuated tubes marketed under the trade names Vacutainer and Venoject were examined. The APTT of heparinized blood collected in these tubes correlated poorly (r = 0.04 to ...
متن کاملAnti-factor Xa and activated partial thromboplastin time measurements for heparin monitoring in mechanical circulatory support.
OBJECTIVES This study investigated the relationship between anti-factor Xa (anti-FXa) and activated partial thromboplastin time (aPTT) for monitoring intravenous unfractionated heparin (IV-UFH) in patients with continuous-flow left ventricular assist devices (CF-LVADs). BACKGROUND CF-LVADs have become mainstream therapy for patients with advanced heart failure. Thromboembolic events, device t...
متن کاملUse of the activated partial thromboplastin time in the control of heparin administration.
H EPARIN, which acts as a direct anticoagulant, in contrast to indirect anticoagulants such as the coumarins or indandiones, has been thought by some investigators to fulfill more nearly the role of tile ideal anticoagulant (1-3). This naturally occurring mucopolysaccharide rapidly decreases the activity of the coagulation system by acting both as an antithromboplastin and as an antithrombin. I...
متن کاملBedside heparin monitoring by activated partial thromboplastin time measured with a dry reagent.
Activated partial thromboplastin time (APTT; also coagulation surface induced time [ID is a routine method for monitoring heparin treatment [2-5]. This time is influenced by the type of reagent, the method of analysis, and the laboratory instrument used; thus, the result will vary from one laboratory to another [6, 7]. Variation in heparin sensitivity between batches of re-agents produced from ...
متن کاملLaboratory Methodologic Approach in Prolonged Activated Partial Thromboplastin Time Test
The pathological activated partial thromboplastin time test is a data that we can find in all clinical laboratories routinely. The hemato-coagulative clinical case here reported aims to point out how the laboratory can provide a correct diagnosis by methodological rational setting and, consequently, carry out an appropriate therapy, or reassure the patient that the pathological data will not ca...
