Effects of home prothrombin international ratio (PT-INR) management in children with mechanical prosthetic valves - Importance of individual correlations between laboratory and CoaguChek device PT-INRs

CoaguChek home monitoring in children with MPAVVR reduced the number of their clinic visits without compromising the safety of warfarin management. Given considerable individual differences in correlations between CoaguChek and laboratory PT-INR, individual correlation needs to be identified to fairly interpret the CoaguChek PT-INR values.
