What color stopper tube is used for coagulation testing?
What color stopper tube is used for coagulation testing?
light-blue top tube
A light-blue top tube (a blood collection tube containing 3.2% sodium citrate) that will be used for coagulation testing must be filled to completion. Under-filling the tube changes the ratio of blood to anticoagulant. This can affect the accuracy of coagulation tests that are performed using this specimen.
What are coagulation tubes?
Vitrex Coagulation Tubes are used to collect venous blood for coagulation tests. Coagulation Tubes have a buffered sodium citrate solution of 0.109 mol/l (3.2%) or 0.129 mol/l (3.8%). Double Tube technology provides an excellent condition for the test of PT and APTT values.
Which tube is used to check coagulation factors?
Venous blood specimens for coagulation assays should be collected into a tube containing 3.2% buffered sodium citrate tube (blue top tube), yielding a whole blood sample with a 9:1 blood to anticoagulant ratio. Inadequate filling of the collection tube will decrease this ratio, and may affect test results.
What is EDTA tube color?
Lavender
Lavender-top tube: Contains K2 EDTA. Use: EDTA whole blood or plasma.
What are the different color tubes for lab tests?
Blood Collection Tubes
| Tube cap color | Additive | Common laboratory tests |
|---|---|---|
| Lavender or pink | Potassium EDTA | Hematology and blood bank |
| Gray | Sodium fluoride, and sodium or potassium oxalate | Glucose (especially when testing will be delayed), blood alcohol, lactic acid |
What color is a citrate tube?
PHLEBOTOMY SERVICES
| STOPPER COLOR | CONTENTS | VOL. |
|---|---|---|
| Red | No additive | 7.0 mL |
| Light Blue | 3.2% Sodium Citrate | 4.5 mL |
| Gold Top (Serum Separator, “SST”) | Contains separating gel and clot activator | 6.0 mL |
| Light Blue – Yellow Label on Tube | Thrombin | 2.0 mL |
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.
What are red top tubes used for?
Red Top: Does not contain an anticoagulant. This tube is used for collecting serum or clotted whole blood specimens. This tube should be used for all drug levels.
What are yellow top tubes used for?
Yellow-top tube (ACD) This tube contains ACD, which is used for the collection of whole blood for special tests. NOTE: After the tube has been filled with blood, immediately invert the tube 8-10 times to mix and ensure adequate anticoagulation of the specimen.
What is the purple tube used for in phlebotomy?
PHLEBOTOMY SERVICES
| STOPPER COLOR | CONTENTS | USES/COMMENTS |
|---|---|---|
| Pearl Top (Plasma Preparation, “PPT”) | Separating gel and (K2)EDTA | Adenovirus PCR Toxoplasma PCR HHV-6 PCR |
| Lavender (“Purple”) | (K2)EDTA | CBC/Diff/Retic/Sed Rate, FK506, Cyclosporin, Platelet Ab, Coombs, Flow Cytometry |
What color tubes do you use for coagulation?
Coagulation Specimen Collection. Specimens for coagulation should be collected in 3.2% Sodium Citrate light blue top tubes. Be careful to not only notice the volume of blood in each tube as described below, but the number of tubes that may be required for the suggested test(s).
What is the action of citrate in coagulation tubes?
ACTION:Citrate is an anticoagulant which binds calcium in the blood. Calcium is required for blood clotting. Since it is bound up the blood cannot clot resulting in a whole blood sample, red blood cells and PLASMA. Coagulation tubes are filled with buffered tri-sodium citrate solution.
What are the different colors of blood collection tubes?
1 Blood Collection Tube Top Colors. 2 Red top tube – Serology and Immunohematology. 3 Red top tube – Chemistry. 4 Light Green top or Green top. 5 Pink top tube (Blood Bank EDTA). 6 (more items)
What are the additives used in blood collection tubes?
Most blood collection tubes contain an additive that either accelerates clotting of the blood (clot activator) or prevents the blood from clotting (anticoagulant). The list below lists the most commonly used blood collection tubes, their additives and uses in laboratory: 1. Red.
