Which tube is used for coagulation?
A light-blue top tube (containing 3.2% sodium citrate) that will be used for coagulation testing must be filled to completion. Please see the attached BD guides for instructions.

What color tube should be collected for coagulation studies quizlet?
Tubes for coagulation tests (light blue) are drawn first (unless blood cultures [yellow] have been ordered, which would then be first). This is followed by plain tubes (red) and then by other anticoagulant tubes.
What is the light blue tube used for in phlebotomy?
These tubes contain the anticoagulant sodium citrate. They are used mostly for coagulation (clotting) studies. They must be completely filled to assure proper ratio of anticoagulant to blood. They must be inverted immediately after filling to prevent clotting.What are light blue tubes used for?

What is a gray top tube?A blood collection tube containing powdered sodium fluoride and/or potassium oxalate, which inhibits glycolysis; ‘gray tops’ are used for glucose tolerance testing because glycolysis in the red cells would cause false-low glucose, for measuring lactate—transported on ice—lactate tolerance.
Article first time published onWhat color tube is used for sodium test?
Red-top tube, gel-barrier tube, or green-top (lithium heparin) tube. Do not use oxalate, EDTA, or citrate plasma.
Why is sodium citrate used for coagulation studies?
Background :Sodium citrate has been used as a coagulation test because factor V and VIII are more stable in a citrated specimen. Ethylenediaminetetraacetic acid (EDTA) has been used for the hematologic test because blood cells are preserved better in the EDTA specimen.
What is a plain tube?
Plain Tubes. This tube does not contain any additive. May be used for CSF (cerebrospinal fluid) testing, for taking samples from blood bags or as discard tube. First clearing tube must be used and discarded when using a butterfly/ blood collection needle for coagulation studies.
What is the gray tube used for in phlebotomy?

What is orange top tube used for?

What is in a purple top blood tube?
Purple blood bottles contain EDTA (ethylenediaminetetraacetic acid), which acts as a potent anticoagulant by binding to calcium in the blood.

Sodium citrate is used as anticoagulant to prevent blood from clotting. Dispense 0.5 ml of sodium citrate into test tube. Add 4.5 ml blood and mix gently by inversion of the stoppered tube. Sodium citrate is effective as an anticoagulant due to its mild calcium-chelating properties.
Do you centrifuge red top tubes?
Red top tubes contain no additives. Red top tubes must be allowed to clot completely (30-60 minutes) prior to centrifugation. Centrifuging the specimen yields serum. NOTE: All drug levels must be drawn in red top tubes only.
