With the PT test, the reference range is between 11 to 13.5 seconds if you are not on anticoagulants. WebbResults indicated that a statistically significant difference was evident between the baseline APTT (30.79 sec) and the mean APTT (55.10 sec) when the PT was within the therapeutic range of 1.5 to 2.5 times the control while on warfarin therapy.
