Blood volume equals Plasma Volume (PV) divided by one (1) minus Hematocrit (Hc). The adult human body contains between 5 and 6 quarts of blood, weighing about 7 to 8 pounds and accounting for about 5% f the body weight.
Please see the webpage for more details on Blood volume.

The most accurate method would be to introduce a marker substance that was not redially excreted or absorbed by tissues, and normally absent in blood.
Then: VmCm =VtCt
Vm = volume of marker Cm=concentration of marker
Vt = volume of blood Ct = concentration in tested blood.
for example if you introduced 1ml of substance with an initial concentration of 1G/ml and the tested blood had a concentration of 0.2 mg/ml, then the blood volume would be:
(1ml)(1g/ml) = (Vt)(.0002G/m)
Vt = 5000ml or 5L
