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