20 C.F.R. § 404.1528 Symptoms, signs, and laboratory findings.
Title 20 - Employees' Benefits
(a) Symptoms are your own description of your physical or mental impairment. Your statements alone are not enough to establish that there is a physical or mental impairment. (b) Signs are anatomical, physiological, or psychological abnormalities which can be observed, apart from your statements (symptoms). Signs must be shown by medically acceptable clinical diagnostic techniques. Psychiatric signs are medically demonstrable phenomena that indicate specific psychological abnormalities, e.g., abnormalities of behavior, mood, thought, memory, orientation, development, or perception. They must also be shown by observable facts that can be medically described and evaluated. (c) Laboratory findings are anatomical, physiological, or psychological phenomena which can be shown by the use of medically acceptable laboratory diagnostic techniques. Some of these diagnostic techniques include chemical tests, electrophysiological studies (electrocardiogram, electroencephalogram, etc.), roentgenological studies (X-rays), and psychological tests.
