what's the difference between plasma and serum
I became an Obstetrician in this one. The difference between serum and plasma is that plasma is the liquid part of blood, that is, whole blood after the removal of red blood cells, white blood cells and platelets by centrifuging. It is prevented from clotting with an anticoagulant such as sodium citrate or EDTA.
Serum (blood) In blood, the serum (/ËsÉªÉrÉm/ or /ËsÉªrÉm/) is the component that is neither a blood cell (serum does not contain white or red blood cells) nor a clotting factor; it is the blood plasma not including the fibrinogens.
