Objective: To determine the risks for bleeding and clotting while monitoring heparin with either anti-Xa or activated clotting time (ACT) in tMCS patients. Methods: A retrospective cohort study was conducted on tMCS patients who received heparin adjusted according to an anti-Xa or ACT protocol. ...
The anti–factor Xa assay is designed to measure plasma heparin (unfractionated heparin [UH] and low molecular weight heparin [LMWH]) levels and to monitor anticoagulant therapy. Therapeutic ranges of heparin are as follows: LMWH: 0.

In the derivation cohort, heparin anti-Xa activity ≤0.2, ≤0.3, <0.1, <0.1 IU·mL reliably ruled out a relevant level of apixaban, rivaroxaban, fondaparinux, and danaparoid, respectively (area under the ROC curve ≥0.99). In the validation cohort, these cutoffs yielded excellent ...
The anti- Xa-activity of the heparin applicated by jet injection was significantly higher (maximal effect after 3 hrs: 0.24 vs 0.20 USP heparin/ml plasma, p < 0.01, area under the time related curve p < 0.01). The data indicate, that the bioavailability of heparin for factor Xa is even...

The data suggest that specimens sent for anti-Xa require prompt handling to prevent falsely elevated values. This observation is new and future research is needed to find the mechanism of this alteration. 展开 关键词: factor Xa inhibitors in vitro diagnostic systems low-molecular-weight heparins ...
Several heparin preparations have been assayed using the Denson and Bonnar anti-Xa assay. The heat defibrination step involved in this assay has been shown to introduce discrepancies into the results, due mainly to co-precipitation of the heparin with fibrinogen. The amount of heparin lost is de...
