A typical adult has a blood volume of approximately between 4.7 and 5 liters, with females generally having less blood volume than males. Blood volume is regulated by the kidneys.
Blood volume (BV) can be calculated given the hematocrit (HC; the fraction of blood that is red blood cells) and plasma volume (PV):
Diagnostic technologies are commercially available to measure human blood volume. A recent radionucleotide study called BVA-100, Blood Volume Analysis is the only FDA approved instrument that provides a measure of Red Blood Cells and Plasma with 98% accuracy.
Blood volume measurement is indicated for the diagnosis and treatment patients suffering from Congestive Heart Failure, Chronic hypertension, Renal Failure and Critical Care.

Famous quotes containing the word humans:
“The difference between humans and wild animals is that humans pray before they commit murder.”

“To not be afraid in our world is the message that doesn’t derive from reason, but maybe from this mysterious capacity given to humans which we call—not without a little embarrassment—faith.”
—Friedrich Dürrenmatt (1921–1990)
“As humans have a prior right to existence over dogs by virtue of being more highly evolved and having a superior consciousness, so women have a prior right to existence over men. The elimination of any male is, therefore, a righteous and good act, an act highly beneficial to women as well as an act of mercy.”
—Valerie Solanas (b. 1940)
