Preparation of serum cups for a lipids panel designed to test cholesterol levels in a patient's blood. Serum (/ ˈ s ɪər ə m /) is the fluid and solvent component of blood which does not play a role in clotting. [1] It may be defined as blood plasma without the clotting factors, or as blood with all cells and clotting factors removed.
Blood serum and blood plasma are similar, but serum does not contain any clotting factors such as fibrinogen, prothrombin, thromboplastin and many others. Serum includes all proteins not used in coagulation (clotting) and all the electrolytes, antibodies, antigens, hormones and any exogenous substances, such as drugs and microorganisms.
Plasma and serum are both derived from full blood, but serum is obtained by removing blood cells, fibrin clots, and other coagulation factors while plasma is obtained by only removing blood cells. [22] Blood plasma and blood serum are often used in blood tests. Tests can be done on plasma, serum or both. [23]
Blood is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), [2] and contains proteins, glucose, mineral ions, and hormones. The blood cells are mainly red blood cells (erythrocytes), white blood cells (leukocytes), and (in mammals) platelets (thrombocytes). [3]
Human serum albumin is the serum albumin found in human blood. It is the most abundant protein in human blood plasma; it constitutes about half of serum protein. It is produced in the liver. It is soluble in water, and it is monomeric. [citation needed]
Human serum albumin is the main protein of human blood plasma. It makes up around 50% of human plasma proteins. It binds water, cations (such as Ca 2+, Na + and K +), fatty acids, hormones, bilirubin, thyroxine (T4) and pharmaceuticals (including barbiturates). Its main function is to regulate the oncotic pressure of blood. [7]
Serum (blood), plasma from which the clotting proteins have been removed Antiserum, blood serum with specific antibodies for passive immunity;
This is composed of blood plasma that has seeped out of ruptured small blood vessels and the inflammatory fluid produced by injured and dying cells. [citation needed] Seromas are different from hematomas, which contain red blood cells, and abscesses, which contain pus and result from an infection. Serous fluid is also different from lymph.
