Recommendations for appropriate activated partial thromboplastin time reagent selection and utilization.
The activated partial thromboplastin time (aPTT) is widely used as a screening coagulation test and for monitoring unfractionated heparin therapy. Various commercial reagents are available, with different performance characteristics, particularly responsiveness to the lupus anticoagulant (LA). Because aPTT reagent selection significantly affects the interpretation of results, we reviewed Colleg...
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...
متن کاملEvaluation of Antiphospholipid Antibodies and Activated Partial Thromboplastin Time in Women with Adverse Outcome of Pregnancy
Adverse outcome of pregnancy is a potentially dangerous complication of conception and affects 15-20% of pregnancies. According to recent studies increased level of blood antiphospholipids antibodies, if accompanied by predisposing factors, can be an adverse event in human pregnancy. The aim of the present study was to compare the maternal serum levels of anticardiolipin and antiphosphatidyl se...
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 کاملThe Use of a Stabilized Partial Thromboplastin Reagent in the Partial Thromboplastin Test.
1THE PARTIAL THROMBOPLASTIN TIME test was originally developed by Langdell et al. (1) as a method of following the therapy of hemophulic patients. These investigators found this test to be extremely sensitive to changes in Factor VIII brought about by whole blood or plasma transfusions. Extensive studies of the partial thromboplastin time test (PTT) by Rodman et il. (2) have shown that this tes...
