What blood tests go in what color tube?
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 tube do you use for glucose testing?
Red-top tube, gel-barrier tube, or green-top (lithium heparin) tube. Do not use oxalate, EDTA, or citrate plasma.
What is FBG in blood test?
The fasting plasma glucose (FPG) test, also known as the fasting blood glucose test (FBG) or fasting blood sugar test, measures the levels of glucose (sugar) in the blood. Used to screen for diabetes, it is a relatively simple, accurate, and inexpensive test that exposes problems with insulin functioning.
What tube is used for fasting glucose?
Processing Instructions: Plasma is preferred specimen type. Green Tube/Plasma: Centrifuge after collection. Gold Tube/Serum: Allow blood to clot for 30 minutes in a vertical position and centrifuge within 2 hours.
What color tube is used for lipid panel?
What color tube is used for DNA testing?
Preferred Samples. CONTAINER: Purple top (EDTA) tube (preferred). Yellow top (citric acetate) or grey top (potassium oxalate/sodium fluoride) tube also accepted.
What color tube is cholesterol?

What color tube is EDTA?
Lavender-top tube: Contains K2 EDTA. Use: EDTA whole blood or plasma.
What color tube has no additives?

What color tube is 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 do the colors on the Vacutainer tubes mean?
Vacutainer tubes are covered with a Color-coded plastic cap that indicates which additives the tube contains. These color indicators help the phlebotomist to easily select the tubes in which the blood should be drawn as per the tests that have to be performed.
What is the most suitable blood collection tube for?
Citrate tubes have been suggested as the preferred tube type by many institutions. Greiner has introduced a glucose-specific tube (Glucomedics) containing NaF/KOx, citrate, and EDTA to minimise glycolysis. The aim was to determine which tube would be the most suitable for accurate glucose estimation in a routine laboratory setting.
How does A Vacutainer blood collection tube work?
A Vacutainer blood collection tube is a sterile glass or plastic tube with a closure that is evacuated to create a vacuum inside the tube facilitating the draw of a predetermined volume of liquid. Most commonly used to draw the blood samples directly from the vein.
