First, we encountered difficulty obtaining the aPTT reagent used at the time, and the alternative aPTT reagent had a large deviation from the previous therapeutic range of 60–90 seconds.

Heparin contamination might be expected to prolong the PT as well as the aPTT, but typical PT reagents today contain heparinase to neutralize any heparin that is present, or are otherwise ...

the APTT reagent sensitivity and instrumentation. The anti-Xa assay may be affected by hyperbilirubinemia, hyperlipidemia (can be cleared by ultracentrifugation) and decreased anti-thrombin levels ...

This assay is readily available and inexpensive. However aPTT reagents are poorly standardized and have different sensitivities to heparin. There is no dose response relationship with heparin. Due to ...

A screening test for a lupus anticoagulant that was performed with an aPTT reagent sensitive to lupus anticoagulant was initially positive, but the addition of phospholipid in the confirmatory ...

The left graph in Panel B shows the factor IX:C level measured by the one-stage method with the Dade Actin FSL activated partial-thromboplastin time (APTT) reagent and the detection of factor IX ...

Prolongation of APTT and TT Prolongation of dRVVT and PT if UFH level exceeds heparin neutralizing ability of a reagent Interference with any assay depending on anti-Xa or anti-IIa activity Clinicians ...

aPTT, Fibrinogen and clotting factors. Automatic start when sample and reagent are mixed together in the cuvette. It has 37°C incubator with 18 samples capacity. PT data are printed with RATIO ...

On Booth #1225 HORIBA Medical will introduce its new generation Yumizen G800 and G1550 hemostasis analyzers, as well as new ready-to-use reagents for frequently undertaken blood coagulation tests.
