What distinguishes serum from plasma?
What distinguishes serum from plasma?
- Serum is the fluid protein of blood treated to prevent clotting, while plasma is the fluid part of blood after it clots.
- Plasma contains a higher concentration of antibodies than serum.

Study Notes
Serology Overview
- Serology is the in vitro study of antigen-antibody interactions.
- Involves examining a patient's blood to identify antibodies.
- Antibodies are also known as serums.
- Serum is the fluid portion of clotted blood.
- Plasma is the fluid portion of blood that has been treated to prevent clotting.
- Seronegative: A person who hasn't been exposed to the pathogen and has no antibodies to that specific pathogen.
- Seropositive: A person who has been exposed to the pathogen and has antibodies to that pathogen.
- Seroconversion is the production of antibodies and a rise in antibody titer, indicative of active infection.
- A low, steady antibody level usually indicates previous exposure to the pathogen.
