Dietary protein, serum albumin and health

When was the last time you thought about your serum albumin? You might have glanced at it the last time you got a lab panel at your doctor’s office, and as long as it was within the normal lab limits, you probably didn’t give it much thought. You should look at it a little more closely the next time you get a lab done because your serum albumin is a pretty good barometer of your overall health.
Albumin is the most abundant protein in blood plasma.
(Let’s take a brief digression to define a few terms so that we’re all on the same page. Blood is blood. Blood is what you get if you cut yourself. When you get your blood drawn, that dark red stuff is the blood, which includes the red blood cells,
white blood cells, and other cellular components. Plasma is what’s left over when all the cells are removed. Typically, when blood is drawn it is put into a tube, and the tube is put into a centrifuge. The whirring of the centrifuge drives all the cells to the bottom of the tube; the yellowish fluid left on top is the plasma. If you put the whole blood in a tube and let it sit, the blood clots into a big glob and drops to the bottom, the clear yellowish fluid left on top is the serum. Basically serum is plasma that has had all the clotting factors removed. For our discussion of albumin, it doesn’t really matter. Albumin is measured in the serum, and so is called serum albumin. But it is the most abundant protein in the blood other than the proteins making up all the cells.)
