Which lab test is vital for patients taking anticoagulants like rivaroxaban?

Monitoring kidney function tests is crucial for patients taking anticoagulants like rivaroxaban because this medication is primarily excreted through the kidneys. Patients with impaired renal function may have an increased exposure to the drug, leading to a higher risk of bleeding and other complications. Regular kidney function assessments help adjust dosages appropriately and ensure that the patient remains within a safe therapeutic range.

While the other tests mentioned have their own importance in overall patient health management, they do not directly address the specific concerns related to rivaroxaban therapy as kidney function tests do. Blood glucose levels are more relevant for diabetes management, liver function tests are important for assessing hepatic metabolism of medications, and a complete blood count provides general information about blood cell levels but does not specifically indicate how well the body is handling anticoagulation therapy. Therefore, evaluating kidney function is essential in ensuring the safety and efficacy of rivaroxaban treatment.
