What does blood separated into clot and serum looks like?
Serum: The serum is the liquid part of blood that is left after the clot has formed. It is made up of water, electrolytes, proteins, hormones, and other solutes. The serum is the part of the blood that is used for most blood tests.
When blood is separated into clot and serum, it looks like this:
* The clot is a dark red, jelly-like mass.
* The serum is a clear, yellow-ish liquid.
The clot and the serum are separated by a thin layer of fibrin.
