Question

What is the term used for blood lacking corpuscles and fibrinogen?

Answer 1

Hint: The liquid part of the blood is not a clotting agent which is obtained after coagulation of the blood. When we talk about corpuscles we mean to say about a minute body or cell, especially red or white blood cells and fibrinogen is a protein that is needed for clotting of the blood.

Complete answer:
The serum is the fluid and solute composition of the blood that takes part in the process of clotting. It is defined as the blood plasma that does not contain clotting factors or corpuscles and fibrinogen. It does not contain white blood cells, red blood cells, platelets or clotting factors but it includes all the proteins that are not required in blood clotting like electrolytes, antibodies, antigens and hormones.

The serum is used in the protein electrophoresis causing false results due to lack of fibrinogen. It can be successfully recovered from infectious disease by using biopharmaceuticals in the treatment of other people with that disease because the antibodies that are generated from the successful recovery are generally the fighter to the pathogen.

The serum is required for many diagnostic tests as well as blood typing and many applications can be used for measuring the concentration of the molecules. One can obtain serum from the blood sample through a clot. Then the sample is centrifuged for removing the clot and the blood cells resulting in the formation of liquid supernatant called serum. Blood serum and plasma are the largest sources of biomarkers that are needed for diagnostic or therapeutics.

Note: Serum has a density of around 1.024g/ml which is used for diagnosing the cholesterol, proteins, sugar level etc., that is present in the blood. It contains the remaining part of the blood that is less than the plasma. Apart from this, the serum also contains antibodies to cross-react with the recipient antigen.
