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)
