Is plasma from which the proteins involved in blood clotting have been removed?

Yes, plasma from which the proteins involved in blood clotting have been removed is called serum. During the process of blood clotting, clotting factors are activated and consumed, leading to the formation of a clot. Once the clot is removed, the liquid remaining is serum, which contains water, electrolytes, nutrients, hormones, and waste products but lacks clotting proteins like fibrinogen.
