Medical Signs
A medical sign is an objective indication of some medical fact or characteristic that may be detected by a physician during a physical examination or by a clinical scientist by means of an in vitro examination of a patient.
Signs may have no meaning to the client, and may even go unnoticed, but may be meaningful and significant to the healthcare provider in assisting the diagnosis of medical condition(s) responsible for the patient's symptoms.
Examples include elevated blood pressure, a clubbing of the fingers (which may be a sign of lung disease, or many other things), and arcus senilis.
The term sign is not to be confused with the term indication, which denotes a valid reason for using some treatment.

Famous quotes containing the words medical and/or signs:
“There may perhaps be a new generation of doctors horrified by lacerations, infections, women who have douched with kitchen cleanser. What an irony it would be if fanatics continued to kill and yet it was the apathy and silence of the medical profession that most wounded the ability to provide what is, after all, a medical procedure.”
—Anna Quindlen (b. 1952)
“One of the signs of passing youth is the birth of a sense of fellowship with other human beings as we take our place among them.”
—Virginia Woolf (1882–1941)
