Usage
Common tests include blood tests for glucose, liver enzymes, levels of electrolytes such as calcium, sodium, and potassium, and tests for drugs.
Purposes of testing include protecting the blood supply, monitoring the levels of drugs given and providing information to assist in the diagnosis and treatment of disease. These tests are generally run in hospital pathology laboratories and can in specific instances also be carried out in doctors’ surgeries, in high street pharmacies or by patients themselves.

Famous quotes containing the word usage:
“...Often the accurate answer to a usage question begins, “It depends.” And what it depends on most often is where you are, who you are, who your listeners or readers are, and what your purpose in speaking or writing is.”
—Kenneth G. Wilson (b. 1923)
“Pythagoras, Locke, Socrates—but pages
Might be filled up, as vainly as before,
With the sad usage of all sorts of sages,
Who in his life-time, each was deemed a bore!
The loftiest minds outrun their tardy ages.”
—George Gordon Noel Byron (1788–1824)
“I am using it [the word ‘perceive’] here in such a way that to say of an object that it is perceived does not entail saying that it exists in any sense at all. And this is a perfectly correct and familiar usage of the word.”
—A.J. (Alfred Jules)
