What is serum sample?
To obtain serum, a blood sample is allowed to clot (coagulation). The sample is then centrifuged to remove the clot and blood cells, and the resulting liquid supernatant is serum.
Why do we use serum samples?
In general, serum samples (red top tubes) are preferred for chemistry testing. This is because our chemistry reference intervals are based on serum not plasma. In general, there is little difference between serum and plasma, except for certain analytes.
What is the definition of serum in biology?
Listen to pronunciation. (SEER-um) The clear liquid part of the blood that remains after blood cells and clotting proteins have been removed.
What is serum in research?
Human serum, the fluid portion of the blood obtained after removal of fibrinogen and other clotting factors, is used for many important applications, including human cell culture, drug testing, tissue typing, and cell therapy research. Human blood serum does not contain white blood cells, red blood cells, or platelets.
How do you get a serum sample?
1) Collect blood in appropriate serum separator tube. 2) Gently invert the tube 8-10 times, and let tube sit in an upright position for at least 15-30 minutes at room temperature to allow the blood to clot. 3) Label sample with appropriate study code.
What is serum in medical?

How do you take a serum sample?
Collection Procedure
- Collect blood in appropriate serum separator tube.
- Gently invert the tube 8-10 times, and let tube sit in an upright position for at least 15-30 minutes at room temperature to allow the blood to clot.
- Label sample with appropriate study code.
How do you make a serum sample?
Serum Preparation
Collect whole blood in a microcentrifuge tube. After collection of the whole blood, allow the blood to clot by leaving it undisturbed at room temperature. This usually takes 15-30 minutes. Remove the clot by centrifuging at 1,000-2,000 x g for 10 minutes in a refrigerated centrifuge.
What is serum made from?

Why serum is used for diagnosis?
Many disease processes can cause changes in the concentrations of serum proteins. Therefore, the determination of their concentrations and the evaluation of changes in their concentrations during the disease process may provide important diagnostic information for assessing the health state.
How do you find the serum in a blood sample?
To separate serum, allow blood in red top collection tubes (“Vacutainer”) to clot at room temperature, undisturbed for a minimum of 30 to a maximum of 60 minutes. 2. Remove clot by centrifugation at 1,000-1,500 x g for 10 minutes using a refrigerated centrifuge.
What serum contains?
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. 8. Serum contain antibodies and cross react with recipient antigen.
What is difference between serum and plasma?
Serum and plasma both come from the liquid portion of the blood that remains once the cells are removed, but that’s where the similarities end. Serum is the liquid that remains after the blood has clotted. Plasma is the liquid that remains when clotting is prevented with the addition of an anticoagulant.
