The minimum centrifugation time for specimens drawn in serum seperator tube is: |
|
|
|
True |
Prothrombin (pt) time will be automatically rejected if the tube is not filled until the vaccuum is exhausted T/f |
Light blue has 9:1 ratio |
|
|
True |
Arteriospasm, hematoma, and infection are complications associated with arterial puncture. T/f |
|
|
|
It slows down cell metabolism during transport |
Tubes with blood specimens should be transported in the upright position, but not because of this: |
|
|
|
Cryoglobulins |
This speciman requires the use of a prewarmed or heel warmer during transport |
|
|
|

|
|
|
1 hour |
How long would you have to wait until blood in red glass tube clots completely in room temp |
|
|
|
The difference in density between the plasma/serum and the formed elements |
This variable has the largest effect on the seperation of plasma/serum from the formed elements via centrifugation |
|
|
|
Specimen may become icteric because of hemolysis |
What doesn't occur with an unbalanced centrifuge |
