Overview

There are no diagnostic laboratory findings associated with carotid body tumor. However, since these tumors originate from extra-adrenal chromaffin tissue of the autonomic nervous system, they may be capable of catecholamine productions.

Laboratory Findings

• There are no diagnostic laboratory findings associated with the carotid body tumor.
• Some patients with carotid body tumor may have elevated concentration of urine catecholamines, which is usually suggestive of hormonal activity of the tumor.
