Instead, calibrated TT and anti-Xa assays offer specific and accurate concentration monitoring under special situations.
All samples for which anti-Xa assay and antithrombin activity were performed simultaneously with free Hb and bilirubin determination from inpatients on ECMO receiving intravenous UH were extracted from the clinical patient database together with the daily infused dose of UH.
To confirm the heparin concentration, heparin was also measured with an anti-Xa assay on the MDA (BioMerieux).
The correlations between clotting time values and actual heparin concentrations as determined by the anti-Xa assay were poor for each of the tests evaluated.
Heparin concentrations determined with DNNS-based electrodes correlate well with those determined with the previously reported heparin sensor-based method [11, 14], the Hepcon assay, and the chromogenic anti-Xa assay (Table 1).
