Laboratory testing in patients with AR should be guided by the clinical scenario. For example, in patients with AR due to suspected infective endocarditis, peripheral blood counts and cultures may help to clarify the diagnosis and to identify the causative organism. Specific serologic tests may assist in the diagnosis of rheumatologic causes. Laboratory assessment of renal and hepatic function may play an important role in determining a patient's eligibility for certain vasodilator or other drug therapy.
