Assuming a therapeutic range of 0.35-0.70 U/ml of hep arin, the therapeutic aPTT ratio ranges in heparinized, acute-phase plasma were 1.5-3.0 for actin and 2.5-4.5 for Cephotest, Platelin, and Thrombosil. These results un derscore certain limitations in monitoring heparin therapy with the ...

This indicates that a uniform therapeutic range of 1.5-2.5 calculated by the APTT ratio may not be appropriate for all reagents. Reagent sensitivity in ex vivo samples was substantially different to that in in vitro samples.The results of this large series of laboratories clearly indicate that ...

The normalized APC‐SRETP is defined as the ratio of α2‐macroglobulin‐thrombin (α2M‐IIa) determined in the presence and absence of APC divided by the same ratio determined in pooled normal plasma. The pooled normal plasma used for the ETP‐based test was obtained using 0.1 volume of...
In all patients, two APTTs were performed, one with each reagent, on 1:1 mixtures of test plasma and normal plasma (MIXCON-LA assay). The ratio between the two clotting times was divided by the corresponding ratio for the normal plasma. This final lupus ratio (LR) was used for ...
