A blood test is a laboratory analysis performed on a blood sample that is usually extracted from a vein in the arm using a needle, or via fingerprick. Blood tests are used to determine physiological and biochemical states, such as disease, mineral content, drug effectiveness, and organ function. They are also used in drug tests.

Famous quotes containing the words blood and/or test:
“We, the soldiers who have returned from battles stained with blood; we who have seen our relatives and friends killed before our eyes; we who have attended their funerals and cannot look in the eyes of their parents; we who have come from a land where parents bury their children; we who have fought against you, the Palestinians—we say to you today, in a loud and a clear voice: enough of blood and tears. Enough.”
—Yitzhak Rabin (1922–1995)
“I have come to believe ... that the stage may do more than teach, that much of our current moral instruction will not endure the test of being cast into a lifelike mold, and when presented in dramatic form will reveal itself as platitudinous and effete. That which may have sounded like righteous teaching when it was remote and wordy will be challenged afresh when it is obliged to simulate life itself.”
—Jane Addams (1860–1935)
