There are many different types of blood tests that doctors use to diagnose and treat patients. Two of the most common tests are plasma and serum tests. Although these tests may seem similar, there are actually some important differences between them. Plasma is the liquid part of the blood that contains clotting factors and proteins. Serum is the liquid part of the blood that doesn’t contain clotting factors.
What is Plasma ?
Plasma is the fourth state of matter. It is a gas that has been heated to such a high temperature that the electrons have been stripped from the atoms, creating a soup of free electrons and ions. Plasma is often referred to as the “fifth element.”
Plasma is found in stars and fusion reactors. It is also present in lightning bolts and fluorescent lights. In fact, plasma makes up more than 99% of the visible universe.
What is Serum?
Serum is a clear, yellowish liquid that separates from clotted blood. It is the blood component that contains all the clotting factors and serum proteins. Serum proteins include albumin, antibodies, and transport proteins.
The main function of serum is to maintain oncotic pressure, which is the force that keeps fluid in the blood vessels. Serum also helps transport hormones, nutrients, and lipids throughout the body; fights against infection; and regulates immune responses.
Main differences between Plasma and Serum
There are two main types of blood: plasma and serum. Plasma is the liquid part of the blood that contains all the clotting factors, while serum is the liquid part of the blood that does not contain any clotting factors. Here are some more differences between these two types of blood:
Plasma is mainly made up of water (90%), while serum is made up of proteins (90%).
Plasma contains all the clotting factors, while serum only contains some of them.
Plasma can be used to treat conditions such as hemophilia, while serum cannot.
Similar Frequently Asked Questions (FAQ)
What are the differences between plasma and serum?
Plasma and Serum are two terms that are often used interchangeably in medical laboratories, but there is a big difference between the two. Plasma is the clear, straw-colored liquid that makes up about 55% of your blood. It contains all the proteins that are found in your blood, including clotting factors, antibodies, and enzymes. Serum is the clear liquid that separates from your blood when it clots. It does not contain any clotting factors or antibodies.
So what’s the big difference between plasma and serum? The answer lies in the proteins. Since plasma contains all the proteins found in your blood, it can be used to treat a variety of conditions. For example, plasma transfusions can be used to treat patients with liver disease or severe burns.
In conclusion,it is important to know the difference between plasma and serum in order to ensure that you are getting the correct treatment for your medical condition. Plasma is the liquid portion of blood that contains white blood cells, red blood cells, and platelets. Serum is the liquid portion of blood that does not contain white blood cells, red blood cells, or platelets. If you are ever in doubt, be sure to ask your doctor or medical professional.
