What is the main purpose of using anticoagulants when separating plasma from blood?

To enhance the formation of the buffy coat in the separated plasma

To produce a more straw-colored and hazy plasma sample

To prevent the conversion of fibrinogen to fibrin, which would cause the blood to clot (correct)

To increase the centrifugal force on the blood sample during separation

What is the primary purpose of centrifuging a blood sample to separate serum?

To increase the concentration of formed cellular elements in the serum

To speed up the clotting process and facilitate the conversion of fibrinogen to fibrin

To enhance the formation of the buffy coat layer in the separated serum

To separate the plasma and serum fractions based on their different densities (correct)

What is the main difference between plasma and serum in terms of their composition?

Serum contains more formed cellular elements than plasma

Serum is slightly hazy, while plasma is straw-colored

Plasma contains the buffy coat, while serum does not

Plasma contains fibrinogen, while serum does not (correct)
