||Serum is the liquid part of the blood after the coagulation.
||Plasma is a clear and yellowish fluid part of the blood.
||Serum is the water fluid from blood without the clotting factors.
||Plasma is the blood fluid that contains blood clotting agents.
||Volume of serum is less in comparison to plasma.
||Plasma is a clear yellow liquid which is 55% of total volume of blood.
||Serum is acquired from the process of spinning after clotting.
||Plasma is acquired from the process of spinning before clotting.
||Serum is more difficult and time consuming to separate.
||Plasma is easier and less time consuming to separate as compared with serum.
||Use of Anticoagulants
||Serum does not need anticoagulants for separation.
||Anticoagulants are necessary to separate plasma.
||Serum contains proteins, electrolytes, antibodies, antigens and hormones.
||Plasma is considered as the medium of blood in which RBCs (Red Blood Cells), WBC (White Blood Cells) and other components of blood are suspended.
||Serum contain antibodies and cross react with recipient antigen.
||Blood plasma contains antibodies, a type of protein that can fight a substance considered foreign to the host body.
||Serum contains proteins like albumin and globulins.
||Plasma contains the clotting factors and water.
||Serum contains 90% water.
||Plasma contains 92-95% water.
||Serum can be stored at 2-6 degrees centigrade for several days.
||Frozen plasma can be stored for up to a year.
||Serum has a density of approximately 1.024 g/ml.
||Plasma has a density of approximately 1025 kg/m3, or 1.025 g/ml.
||Cells are usually attached together by clot formation.
||Cells are not attached together and suspended in plasma.
||Serum is the most preferred part of blood used in checking blood groups.
||Plasma is delivered to the patients who lack blood cells.
||Serum is an important source of electrolytes and animal sera are used as anti-venom, anti-toxins, and vaccinations.
||Plasma contains proteins that help in the transportation of material such as glucose and other dissolved nutrients through the blood.
||Serum is used for various diagnostic tests used for determining the levels of hCG, cholesterol, proteins, sugar, etc., in the blood.
||Plasma aids in the maintenance of blood pressure and in the regulation of body temperature
