27
Let gold tubes sit _____ before centrifuge
30 minutes
28
During centrifugation of Gold tubes...
polymer barrier moves upward to the serum-clot interface | Separates serum from fibrin and cells
29
RST
Rapid Serum Tubes
30
Orange and Grey/Yellow Tubes are
Rapid Serum Tubes
31
Orange Tubes Additive
Thrombin
32
Thrombin additives will clot blood in
less than 5 minutes
33
Red additive
None
34
Red tubes are used for collection of
serum
35
Blood collected in Red Tubes ______ clot.
WILL
36
How long does it take a fibrin clot to form in a red tube?
30 minutes
37
If you centrifuge a red tube what will happen?
Serum will separate from the blood
38
Clear/White Additive
None
39
Clear/White Tubes are used for
Discard or Secondary Specimen collection
40
Green/Mint Green/Gray and Green additives
Anticoagulants Sodium Heparin, Annomium Heparin, and Lithium Heparin
41
Green/Mint Green tubes are used for any test requiring
plasma or whole blood
42
Why is the green tube good for a STAT test?
The whole blood can be tested without clot formation or centrifuge
43
Why is heparinized plasma or whole blood better for potassium testing rather than the serum in red tubes?
Serum in red tubes can contain sporadic increased potassium levels as a result of the potassium released by the platelets during blood clotting
44
Lithium Heparin tubes are used for
``` Glucose Blood Urea Nitrogen (BUN) Ionized Calcium Creatinine Electrolyte Studies ```
45
Lithium Heparin is not used for any test measuring...
lithium or folate levels
46
Sodium Heparin is not used for any test measuring
sodium concentration
47
Lithium Heparin with gel is used for...
plasma determinations in chemistry
48
Specific gravity
weight compared to water
49
Why use a lithium heparin with gel instead of a lithium heparin tube?
Because once centrifuged the gel forms a stable barrier separating plasma from the cells, allowing for easy collection of plasma
50
Lithium Heparin with gel inversion #
5-10 immediately
51
PST
Plasma Separator Tube
52
What test should Green tubes not be used for?
Blood smears that are to be stained with wright's stain as the Heparin causes blueish tint.
53
What tubes are best for assays that require heparinized plasma?
Mint green tubes because they have gel to separate the plasma from RBCs
54

69
Grey tubes are primarily used for
glycolytic inhibition testes
70
Sodium Fluoride prevents
glycolysis
71
glycolysis
breakdown or metabolism of glucose by blood cells
72
Grey Tube additives are also known as
Antiglycolytic agent and glycolytic inhibitor
73
Grey tubes should never be used for ____ and ____ determinations.
Sodium; Potassium
74
Why should grey tubes not be used for hematology studies?
Oxalate distorts cellular morphologic features
75
What can happen if a lavender tube is underfilled?
Falsely low blood counts Falsely low hematocrits Staining alterations on blood smears Erroneous morphologic changes to RBCs
