Explain the difference between plasma and serum and how you would collect to obtain both specimens. ANS: The liquid portion of blood is called plasma and is obtained from a specimen that has been collected in a tube containing an anticoagulant. Plasma contains fibrinogen. Serum is the liquid portion of blood that does not contain fibrinogen (plasma minus fibrinogen) and is collected by drawing a tube that does not have a coagulant because the specimen needs to clot.
