Why use plasma concentration rather than blood concentration in monitoring drug concentration in the body?

Most compounds are given as their concentration in blood plasma as well as with the conditions of collection. It is a form of standardization used in order to compare results across laboratories and over time. As blood volume and percent hematocrit (a measure of red blood cells) are fairly constant relative to body mass using the concentration in plasma ensures consistency in measurement. Another factor is that red blood cells are not equilibrated with the concentration of all compounds outside the cell equally. Transportation of compounds across the cell membrane is regulated.

Solute and solvent in your blood?
http://www.flash-med.com/LabNormal.asp That link should provide with just about every possible "normal" concentration of just about every possible blood solutes. It seems rather exhaustive. Good luck!

What is hemo-concentration?
Hemoconcentration occurs when there is an increase in the concentration of blood cells as the result of the loss of plasma from the bloodstream. A decrease in volume of plasma and an increase in red blood circulating.
What is plasma viremia titer?
It is a way of representing the concentration of the virus particles in blood plasma

Why is the concentration of hydrogen or hydroxide ions in blood plasma or cell cytoplasm critical?
The concentration of hydrogen or hydroxide ions in blood plasma and cell cytoplasm is critical. These hydrogen and hydroxide ions can be combined to form water.
What carries blood with high concentration of urea?
the blood plasma carries waste products, including urea.
What causes hemo-concentration?
When a person loses blood plasma, a rise in cellular concentration as well as protein concentration occurs. This is hemoconcentration when this occurs.
What affects the concentration of sodium in the blood?
The concentration of sodium in the blood plasma depends on two things: the total amount of sodium and water in arteries, veins, and capillaries

The blood colloid osmotic pressure mostly depends on?
concentration of plasma proteins.
What is plasma decay?
Plasma decay refers to the time that it takes for the concentration in blood plasma of a substance to reach one-half of its steady-state value. This is also referred to as the plasma half-life.
