Differences between Serum and Plasma
Differences between Serum and Plasma
S.N. |
Serum |
Plasma |
1 |
Serum is the undiluted, extracellular portion of blood after adequate coagulation is complete. | Plasma is a clear, straw-colored watery portion of the blood in which several types of blood cells are suspended. |
2 |
Serum is part of blood which lack clotting factor. | Plasma is composed of serum and clotting factor. |
3 |
Acquired after centrifuging of coagulated blood. | Acquired after centrifuging blood with anti-coagulant. |
4 |
Anticoagulant are not needed to separate the serum. | Anticoagulant are required to get plasma. |
5 |
Less volume in comparison to plasma. [Plasma – Fibrinogen (Clotting factor)= Serum] |
Consists 55% of total volume of blood. |
6 |
Difficult to separate and is time consuming. | Comparatively easier and less time consuming than serum. |
7 |
Lack fibrinogen. | Contain fibrinogen. |
8 |
Consists 90% water with dissolved proteins, minerals, hormones and carbon dioxide. | Consists ~92% water with Proteins, Salts, Lipids, Glucose. |
9 |
Density of serum is 1.024g/ml. | Density of plasma is 1.025g/ml. |
10 |
Can be reserved at 2 to 6 degrees centigrade for many days and may be stored at a low temperature in the freezer for various months. | Can be stored for even 10 years from the date it has been collected. |
11 |
An important source of electrolytes. | Plasma is the main medium for excretory product transportation. |
12 |
Cells are usually attached together by clot formation. | Cells are not attached together and suspended in plasma. |
13 |
Most preferred part of blood used in checking blood groups and diagnosis of diseases. | Transferred to the patients who are suffering from hemophilia, shocks, burns, and other clotting problems and also those who lack blood cell. |

Dr.required plasma oxalate test but lab did Serum oxalate .Is that Ok ?
Plasma does not contain antibodies????
very informative thanks …am doing Biochemistry..and this piece is helpful
#7 I believe is referring to the antibodies on the red blood cells.
Antigens are on the RBC..
the document was so helpful as i did my assignments keep up the good work.
plasma has antibodies..but of low quantity to serum..i stand to be corrected.
Good site. provided me with exactly what I wanted.
I also found it helpful.thanks
Website provided me with good information. thank you
Hi sir.i am doing post graduation in microbiology.i found ur notes very helpful.thank you very much.
You are such a good not to temper with.thanks sir.
Thanks To You Alot Coz I Found It Very Useful In My Assignment Given To Me Where I’m Doing My Industrial Training.
thank u very much for you good summarised notes.
Hello. Thanks to you for this summarized notes. I did Biomedical Laboratory and i see this web so helppful. Keep up
thanks it is helpful to complete my assigment.
Was very helpful in preparation for my exam. Tanks alot.
am a laboratory assistant it has helped me alot
very helpful in my studies.
Why serum sample is prefers in Micro biology lab ??????
very helpful, thanks alot
I am Animal scientist, I was really appreciated
this is a powerful piece of information, so short and precise,i liike it
This is highly enriching, I appreciate .
This make it easy learning, i put forth my appreciation. Thakns.
The word in progress, becaus learning is simplified by this calibers.
Hlpful documnt
Thnx 4 publishng d answrs
They hlpd me a lott…
Thnx again…..!
nice work i appreciate
very good. exactly what I want to see. thanks
A broad differences between serum and plasma. I have been looking for this type of differences since but I have gotten it today. Thanks a lot
If there are two samples and how can i know if they are serum or plasma
Very much helpful for us.thanks
very useful
very informative thanks
