Effect of heparin neutralisers on the APTT of heparinised plasma. a) APTT values of Na-citrate plasma with heparin added in vitro to a final concentration of 0.5 U/ml. APTT reagent with cephalin 1/100 as phospholipid source. APTT in this heparinised plasma was unmeasurable without heparin neutraliser, i.e. clotting times >120 sec. The figure shows the clotting times when increasing concentrations of the different heparin neutralisers were added. b) APTT values of Na-citrate plasma with heparin added to a final concentration of 0.5 U/ml. APTT reagent with cephalin 1/3200 as phospholipid source. Again, APTT was >120 sec. when no heparin neutraliser were added. The figure shows the clotting times when increasing concentrations of the different heparin neutralisers were added.
