The clear, fluid portion of blood lacking both blood cells and fibrinogen It is the fluid remaining after coagulation of plasma, the noncellular liquid faction of blood (See 742)
A watery fluid from animal tissue, especially one that moistens the surface of serous membranes or that is exuded by such membranes when they become inflamed, such as in edema or a blister
The liquid part of blood (as opposed to blood cells) that makes up about half its volume Serum differs from plasma in that the blood sample has clotted A centrifuge is used in the laboratory to separate serum from cells after blood has clotted
1) The clear portion of any body fluid; the clear fluid moistening serous membranes 2) Blood serum; the clear liquid that separates from blood on clotting The cell-free portion of the blood from which the fibrinogen has been separated in the process of clotting
Serum is the fluid portion of the blood ; it is essentially similar in composition to plasma but lacks fibrinogen and other substances that are used in the coagulation (blood clotting) process
The clear yellowish fluid obtained upon separating whole blood into its solid and liquid components after it has been allowed to clot. Also called blood serum
The liquid portion of the blood after it clots The blood is collected in sterile tubes without an anticoagulant and allowed to clot The liquid portion or serum is removed after the clot forms Most chemical tests are performed using serum
the clear or slightly yellowish liquid that remains after the plasma portion is allowed to clot; blood is comprised of a plasma portion (55%) and a cellular portion (45%); plasma contains water, salts, and plasma proteins (albumin, fibrinogen, antibodies) whereas the cellular portion contains red blood cells (erythrocytes), platelets, and white blood cells (leukocytes)
is the clear, slightly yellow fluid which separates from blood when it clots In composition it resembles blood plasma, but with fibrinogen removed Sera containing antibodies and antitoxins against infections and toxins of various kinds (antisera) have been used extensively in prevention or treatment of various diseases 43
