Breaking up of red blood cells resulting in the release of hemoglobin
28
What color does hemoglobin cause the serum/plasma to be?
Pink/red
29
What can cause hemolysis?
- too small of a needle - collapsing vein by putting too much pressure on it - vigorously shaking the blood tube

To yield serum
40
What color is serum?
Straw colored
41
Anticoagulants have what function?
Prevent clotting
42
Hemoconcentration...
Blood concentration of large molecules such as proteins, cells, and coagulation factor increases
43
