Clinical Application
Direct oral anticoagulants (DOACs) do not usually require routine monitoring due to their predictable pharmacology.

Knowledge of drug level during bleeding, thromboembolic event, invasive procedures, extremes of body weight, suspected non-compliance or overdose may be useful in clinical management.

Routine coagulation tests must not be used to predict or monitor DOAC effect.
