What tests go in what color tubes?
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 are the different blood collection tubes used for?
Blood collection tubes containing heparin, which stabilizes the red blood cell membranes, are used for specialized hematology studies, such as red cell fragility tests and several specialized chemistry tests. Blood collection tubes containing sodium citrate are used for coagulation studies.
What are the different color stoppered tubes used in specimen collection?
Standard order of draw: BLOOD CULTURES, royal blue, red, light blue, SST (Gold), green, tan, yellow, pink, pearl, lavender.
Why do you have different Colour caps for blood collection tubes?
Tubes often include additives that mix with the blood when collected, and the color of each tube’s plastic cap indicates which additives it contains. Blood collection tubes expire because over time the vacuum is lost and blood will not be drawn into the tube when the needle punctures the cap.
What color tubes are drawn last?
1. Collect citrate tube (blue top) last, after 20mL of blood has been withdrawn for other testing, or as waste. Just prior to drawing the blue top tube as the last tube, draw 1mL into a discard blue top tube to prevent cross contamination from the additive of previously drawn tubes.
What is the purple top tube used for?
The purple top tube provides blood for infectious disease tests and ascertaining important data such as ABO/Rh (blood type), as well as whether the blood is positive or negative for cytomegalovirus (CMV), HIV, hepatitis, and West Nile virus, to name a few.
What tests are red top tubes used for?
Red top – Tube without gel separator, used mainly for serology and chemistry testing. 10mL Red top tubes are used in Blood Bank for antibody screens.
What is the purple top blood test for?
Can I ask for a complete blood count?
A doctor could order a CBC to test for anemia or order fewer tests by requesting a hemoglobin and hematocrit (H and H) test. Rapid testing for these results is available, with levels sometimes reported in 10 minutes or less. However, other laboratory tests may take hours to result.
What is green top tube used for?
Lithium Heparin (Green-Top Tube)*: This tube is used for the collection of heparinized plasma or whole blood for special tests. *Note: After the tube has been filled with blood, immediately invert the tube gently several times to prevent coagulation.
What is Tiger top tube used for?
Serum Separator Tube (SST) (Tiger Top): Does not contain an anticoagulant but contains a clot activator and serum separator gel. This tube is used for collecting serum. Light Blue: Contains the anticoagulant sodium citrate. This tube is used for preparing citrated plasma for coagulation studies.
What do the different colored blood tubes mean?
Red: Contain NO anticoagulants, used for serum testing. Serum is fluid that is left behind after the cells are removed due to clotting. Gold: Contains a clot activator and special gel to separate serum from the cells. Purple: Contains a clot blocker and are used for complete blood count(CBC).
What are the different colors of blood test tubes?
Specific colors indicate a presence of certain additives. They are categorized as tubes for coagulant blood tests, anticoagulant blood tests and other types of tests. Tubes under this category are often used in patients with a bleeding disorder or are using a blood thinner medication.
What are the different colors of Vacutainer tubes?
Gold (commonly known as Serum Separator tube) Polymer Gel and Powdered Glass Clot activator: BMP, CMP, LFT, KFT, Lipid Profile and other biochemistry assays, Serological tests etc. 6.) Red: Powdered glass Clot Activator: BMP, CMP, Lipid Profile, Serology tests, Therapeutic drug monitoring, blood bank procedures etc. 7.) Dark green: Sodium Heparin
What kind of tube is used for anticoagulant blood test?
Performing an anticoagulant blood test requires a different type of tube, one that don’t contain a clot activator. Instead, it contains an additive that binds to calcium ions, inhibiting the proteins that lead to coagulation of blood specimens. Some of the tubes used are those with light blue, green, gray, dark blue and lavender or pink stoppers.
What are the uses of blood collection tubes?
Laboratory Uses: Serum testing (glucose, cholesterol, triglycerides, HDL, potassium, amylase, alkaline phosphatase, BUN, CK, liver enzymes), blood bank, serology (RH Typing, Antibody screening, Red Cell Phototyping, DAT, RPR, monospot, rheumatoid factor, ANA)
