What is blood serum vs Plasma?
Serum and plasma both come from the liquid portion of the blood that remains once the cells are removed, but that’s where the similarities end. Serum is the liquid that remains after the blood has clotted. Plasma is the liquid that remains when clotting is prevented with the addition of an anticoagulant.
Why serum is used instead of plasma?
In general, serum samples (red top tubes) are preferred for chemistry testing. For example, LDH, potassium and phosphate are higher in serum than plasma, because of release of these constituents from cells during clotting. Protein and globulins are higher in plasma than serum, because plasma contains fibrinogen.
How do you separate blood plasma and serum?
PLASMA
- Draw 12 mL of whole blood for each 5 mL of serum or plasma needed. Collect in an appropriate collection tube.
- Centrifuge for at least 15 minutes at 2200-2500 RPM.
- Pipette the serum or plasma into a clean plastic screw-cap vial and attach the label. Do not transfer red cells to the vial.
What color is plasma?

Why you should never donate plasma?
Plasma is rich in nutrients and salts. These are important in keeping the body alert and functioning properly. Losing some of these substances through plasma donation can lead to an electrolyte imbalance. This can result in dizziness, fainting, and lightheadedness.
Why is my plasma so dark?
Discoloration of the plasma due to medication or diet The reason for the colour of the plasma is the yellow breakdown product bilirubin of the red blood cells.
Why is blood red if plasma is yellow?
Blood plasma is yellow in colour because of the presence of a yellow pigment called bilubrin. The blood cells RBC give a red colour to normal blood. When blood cells are removed what remains is plasma. Plasma is made of water and proteins.
What does Brown plasma mean?
Causes of brown plasma Hemolysis is the most common cause of dark red or brown plasma. Hemolysis releases hemoglobin (Hb) from red blood cells (RBCs) into plasma.
Why is my plasma GREY?
In addition to being reddish-orange and green, plasma can also sometimes be milky white and cloudy. This phenomenon, known as lipemia, occurs when a donor has consumed fatty food prior to donating. Cloudy blood plasma cannot be used to manufacture plasma products.
