Green-top tube: Contains sodium heparin or lithium heparin. Use: Heparinized whole blood or plasma. Send plasma in a plastic transport tube labeled “Plasma, Sodium Heparin” or “Plasma, Lithium Heparin.” Send whole blood in a green-top tube. Yellow-top tube: Contains acid citrate dextrose (ACD) solution.
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.
Beside this, What color tube is used for STD testing?
Collect specimen in lavender-top (EDTA), yellow-top (ACD), red-top tube, or gel-barrier tube.
Likewise, What tests are light blue tubes used for?
Light blue-top tube (sodium citrate): Tube contains sodium citrate as an anticoagulant. This tube is used for preparing citrated plasma for coagulation studies. Note: Tube should be inverted several times immediately after blood collection to prevent coagulation.
Also, Why are blood collection tubes color coded?
Vacutainer tubes have a color-coded plastic cap. The color code of the caps indicates the blood additives the tube contains. Additives are chemical substances that preserve the blood for processing in the laboratory. The additives include anticoagulants like EDTA, Sodium citrate and Heparin.
What tube is used for STD testing?
For serum, blood is collected in a red-top tube (without anticoagulants). For plasma, blood is collected in a purple-top tube (with anticoagulants, e.g. EDTA). For safety reasons, the use of an evacuated blood collection system (e.g, Vacutainer® tube) is recommended.
