Overview

Common laboratory tests obtained in a patient with atrial flutter include complete blood count with differential, thyroid function tests, ABG, urinalysis, liver function tests and INR levels.

Laboratory Findings

Laboratory studies in patients with atrial flutter include:

Complete blood count is routinely done to look for anemia
Differential count to look for elevated white cell count in infectious causes like pericarditis
Thyroid function tests are done to look for hyperthyroidism, which is a potential cause of atrial flutter
Blood gas analysis is done to look for hypoxia and carbonmonoxide poisoning
Erythrocyte sedimentation rate
Urinalysis
Liver function tests
Pre-warfarin coagulation screen (INR/aPTT)
