Question: 1 / 400

What does the term "serum" describe?

The liquid that remains after blood clots, containing antibodies and other proteins

The term "serum" specifically refers to the clear liquid that is obtained after the blood has clotted and is separated from the blood cells. It contains a variety of components, including antibodies, electrolytes, hormones, and other proteins that are not involved in clotting. This makes serum vital for many laboratory tests, as it provides a wealth of information about a person's health and can be analyzed for different biochemical markers.

The other definitions mentioned do not accurately capture what serum is. Instead, they focus on other components or functions of blood or bodily fluids. Understanding the composition and role of serum is crucial for various biomedical applications, including diagnostics, as it reflects how the body responds to diseases or infections.
