Blood
Drug-testing a blood sample measures whether or not a drug or a metabolite is in the body at a particular time. These types of tests are considered to be the most accurate way of telling if a person is intoxicated. Blood drug tests are not used very often because they need specialized equipment and medically trained administrators.
Depending on how much marijuana was consumed, it can usually be detected in blood tests within six hours of consumption. After six hours has passed, the concentration of marijuana in the blood decreases significantly. It generally disappears completely within 30 days.
Famous quotes containing the word blood:
“Lord Angelo is precise,
Stands at a guard with envy, scarce confesses
That his blood flows, or that his appetite
Is more to bread than stone. Hence shall we see
If power change purpose, what our seemers be.”
—William Shakespeare (1564–1616)
“The poet sings how the blood flows in his veins. He performs his functions, and is so well that he needs such stimulus to sing only as plants put forth leaves and blossoms.... His song is a vital function like breathing, and an integral result like weight.”
—Henry David Thoreau (1817–1862)
“Your hand found mine.
Life rushed to my fingers like a blood clot.
Oh, my carpenter,
the fingers are rebuilt.”
—Anne Sexton (1928–1974)
