What blood test goes in what color tube?
What blood test goes in what color tube?
The tests each bottle is used for are the same: the purple one is for cell count, the yellow one is for electrolytes, albumin and LDH, the grey one is for glucose, and blood culture bottles can be used for fluid cultures.
What do the colors of blood test tubes mean?
Each color relates to unique additives that are in the tube. Red: Contain NO anticoagulants, used for serum testing. 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). Green & Light Blue: Used for plasma testing.
What are the different types of blood tubes?
Types of tubes
| Tube cap color or type | Additive |
|---|---|
| Blood culture bottle | Sodium polyanethol sulfonate (anticoagulant) and growth media for microorganisms |
| Light blue | Sodium citrate (anticoagulant) |
| Plain red | No additive |
| Gold (sometimes red and grey “tiger top”) | Clot activator and serum separating gel |
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 color is CBC?
The following tests may be drawn in the same Lavender (Purple) top tube: CBC, SED Rate (ESR), Reticulocyte. Draw an extra lavender for each Glycohemoglobin and BNP. EDTA Sodium fluoride (serum tube) For glucose determinations. Oxalate and EDTA anticoagulants will give plasma samples.
What color tube is a CBC?
Lavender
Lavender top tube – EDTA EDTA is the anticoagulant used for most hematology procedures. Its primary use is for the CBC and individual components of the CBC.
What color is the tube for a CBC?

What is EDTA tube used for?
EDTA is the anticoagulant used for most hematology procedures. Its primary use is for the CBC and individual components of the CBC. The larger 6 mL tube is used for blood bank procedures. This tube has no anticoagulant and is used for many chemistry tests, drug levels, and blood bank procedures.
What is a Gold blood test for?
QuantiFERON-TB Gold (QFT) is a simple blood test that aids in the detection of Mycobacterium tuberculosis, the bacteria which causes tuberculosis (TB). QFT is an interferon-gamma (IFN-γ) release assay, commonly known as an IGRA, and is a modern alternative to the tuberculin skin test (TST, PPD or Mantoux).
Why is EDTA tube used for CBC?
Anticoagulants are used to prevent clot formation both in vitro and in vivo. Historically, EDTA has been recommended as the anticoagulant of choice for hematological testing because it allows the best preservation of cellular components and morphology of blood cells.
What is in a CBC?
The complete blood count (CBC) is a group of tests that evaluate the cells that circulate in blood, including red blood cells (RBCs), white blood cells (WBCs), and platelets (PLTs). The CBC can evaluate your overall health and detect a variety of diseases and conditions, such as infections, anemia and leukemia.
What happens if you Centrifuge a CBC?
If specimen is centrifuged before clotting is complete, a fibrin clot will form on top of the cell. This finding is frequent in hemolyzed specimens.
What color tube is used for blood alcohol test?
For alcohol testing, the specimen should be collected in a tube containing sodium fluoride as a preservative. These tubes typically have a gray colored stopper. This preservative is used since it prevents the production or destruction of alcohol by any bacteria in the blood specimen.
What color tube is used for glucose test?
A glucose tolerance test would require a grey vacutainer tube. A vacutainer tube is a sterile tube used to collect blood. It has a coloured rubber lid which creates a vacuum seal that makes the drawing of the blood easier.
What color tube is used for lipid test?
It is ordered in conjunction with the management of anticoagulant therapy, to evaluate the extrinsic pathway, and to moniter coumadin therapy. Tube Color: Blue Top. PT ( Prothrombin Time ) Is used primarily to detect disorders of blood lipids and to evaluate the risk potential for artherosclerosis.
What color tube for blood draw?
The basic order of draw followed by most phlebotomy laboratories is as follows: Yellow Top (or Yellow-Black). This tube is used for blood cultures.
