Which of the following statements is true regarding patients’ need for regular blood tests when on anticoagulants?

Regular monitoring of patients on anticoagulants is essential to ensure that drug levels remain within a therapeutic range. This is crucial for preventing both thromboembolic events and bleeding complications that can arise from either under-anticoagulation or over-anticoagulation. The therapeutic range reflects the optimal levels of the medication that maximize efficacy while minimizing side effects. Regular blood tests, such as INR testing for warfarin patients, allow healthcare providers to adjust dosages as needed based on individual responses and variations in factors like diet, other medications, and changes in health status.

While it is possible for some patients to experience complications from anticoagulation therapy, the necessity for consistent monitoring is key to ensuring safety and efficacy, regardless of how the patient feels. This structured approach forms the foundation of effective anticoagulation management, making it critical for patients on these medications.
