Heparin anticoagulant activity was determined by two assays: a diluted activated partial thromboplastin time (APTT) and an assay based on inactivation of bovine factor Xa, using a clotting system. After a bolus injection, the data fitted neither single exponential nor zero-order clearance. In semi...
Lysis proceeded for 10 min at room temperature and samples were centrifuged as above. OD at 595 nm of supernatants was measured. To confirm RagHemoA phenotype, the clotting time of mouse plasma was determined by activated partial thromboplastin time (aPTT) using a semiautomated coagulometer ...
The aPTT should be between 1.5 and 2.5 times normal when the client is receiving heparin therapy. Monitor for signs of bleeding if the aPTT value is longer than 90 seconds in a patient receiving heparin therapy. White Blood Cells and Differential The normal laboratory value for WBC count has ...
