Laboratories using the aPTT to monitor heparin, need to provide clinicians with a heparin therapeutic range specific for their lot of reagent on their analyzer. An anti-Xa assay is a standardized test ...

Background: Unfractionated heparin (UFH) has been used clinically for 5 decades. Despite being a cornerstone of anticoagulation, UFH is limited by its unpredictable pharmacokinetic profile, which ...

The aPTT plateaus at high heparin levels, responding in a nonlinear or log-linear fashion to the high heparin levels used during invasive procedures. 10 In clinical practice, substantial changes ...

Background: Both the activated partial thromboplastin time (aPTT) and anti-Xa assay can be used to monitor unfractionated heparin (UFH). Following implementation of an anti-Xa method for heparin ...

Although we detected heparin in 28 of the 35 specimens, the DRVVT assay contains heparinase, which neutralizes any heparin effect that might lead to false positive detection of lupus anticoagulant.

Clinical and biochemical timeline of overdose of low-molecular-weight heparin (LMWH). The orange line representing activated partial thromboplastin time (aPTT) is dashed at the beginning, as the first ...
