The cap colors on blood collection tubes tell technicians the tube additives, additive functions and the laboratory tests required. Some collection tubes contain clot activators, which produce serum samples when spun in centrifuges. Other tubes contain anticoagulants, which produce whole blood without a centrifuge and plasma with a centrifuge.
If a CBC is the only test ordered, please draw a Gold tube and discard the gold tube. USES: CBC, MANUAL DIFFERENTIAL, PERIPHERAL SMEAR REVIEW, HEMOGLOBIN AIC. ADDITIVE: None. MODE OF ACTION: Blood clots - serum is separated by centrifugation. USES: Once Serum is separated by centrifugation, pipet serum to Transport Tube. Red Top Tube can be.A vacutainer blood collection tube is a sterile glass or plastic test tube with a colored rubber stopper creating a vacuum seal inside of the tube, facilitating the drawing of a predetermined volume of liquid. Vacutainer tubes may contain additives designed to stabilize and preserve the specimen prior to analytical testing. Tubes are available with a safety-engineered stopper, with a variety.Serum: Draw a sufficient amount of whole blood into a plain, red-top tube or a gold- top (serum gel) tube. If using a gold-top (serum gel) tube, gently invert the tube several times to activate clotting. Allow blood to clot at ambient temperature for 30 minutes. Centrifuge for 10 minutes to separate serum from clot.

First - blood culture bottle or tube (yellow-black stopper) Second - non-additive tube (plain red stopper) Third - coagulation tube (light blue stopper). If just a routine coagulation assay is the only test ordered, then a single light blue stopper tube may be drawn. If there is a concern regarding contamination by tissue fluids or thromboplastins, then one may draw a non-additive tube first.
Red or Gold top tubes contain no chemicals to prevent the blood to clot, so the blood will clot with out being exposed to air. Each specific department in the lab have different colored tubes with.
The PAXgene Blood RNA system consists of PAXgene Blood RNA Tubes (available from BD, cat. no. 762165) for blood collection, stabilization, and transport, and the PAXgene Blood RNA Kit for silica-membrane-based RNA isolation and purification in a spin-column format. Purification can be carried out manually, using a microcentrifuge, or automated on the QIAcube. The CE-IVD-marked tubes and kit.
Most blood collection tubes contain an additive that either accelerates clotting of the blood (clot activator) or prevents the blood from clotting (anticoagulant). A tube that contains a clot activator will produce a serum sample when the blood is separated by centrifugation and a tube that contains an anticoagulant will produce a plasma sample after centrifugation. Some tests require the use.
First - blood culture bottle or tube (yellow or yellow-black top) Second - coagulation tube (light blue top). If just a routine coagulation assay is the only test ordered, then a single light blue top tube may be drawn. If there is a concern regarding contamination by tissue fluids or thromboplastins, then one may draw a non-additive tube first.
General requirements for specimen collection are provided below and should be adhered to in order to prevent specimen rejection.. No additive: Serum: Gold top (SST) No additive: Serum, tube inversions mix blood and clot activator: Dark green top: Sodium heparin: Chromosome testing: Mint green top: Lithium heparin: Plasma, tube inversions prevent clotting: Lavender top: EDTA: Used for whole.
No additive; Serum Separator Tube (SST) contains a gel at the bottom to seperate blood from serum on centrifugation red top-3ed draw No additive; blood clots, and the serum is separated by centrifugation--chemistries,immunology and serolgy,blood bank-crossmatch.
Gold-top vacutainer tubes can be mistaken for yellow-top tubes but serve a very different function. Phlebotomists utilize gold-top tubes to collect specimens for the analysis of blood chemistries, immunology and serological testing. Gold tubes work via a serum separator tube. The plastic tube contains a gel at the bottom that separates blood from serum when put in a centrifuge. These tubes.
Send whole blood in a gray-top tube. Blue-top tube (also light blue-top tube): Contains sodium citrate. Be sure to use only tubes with a 3.2% sodium citrate concentration. These are easily identified by the yellow diagonal stripes on the label. Use: Sodium citrate plasma. Send plasma in a plastic transport tube labeled “Plasma, Sodium Citrate.
IMPORTANT: When using a winged Blood Collection Set for these tests, a discard tube (non-additive KFK 432) should be used to ensure the tube is filled correctly. 2nd Following blood collection, all tubes should be gently inverted 5-10 times (coagulation tubes 4-5 times). Thorough mixing is necessary to.
SST Tube are used to collect blood for clinical biochemistry and immunology. They can improve serum surface and prevent substance exchange between blood cell and serum. Guaranteeing biochemical character and chemical components of serum unchanged evidently for a long time, which do not need to us special tool to transport serum.
