Iowa rates for HCPCS 83497

This blood test measures a breakdown product of serotonin, one of the body's chemical messengers, in the blood. Elevated levels can point to a hormone-producing tumor arising from certain gut or nerve tissue, so the test is often used when a doctor suspects one of these tumors. It is frequently ordered together with related tests for a fuller clinical picture.
