LABORATORY TUBE COLLECTION QUICK REFERENCE GUIDE Avoid SST® blood collection tube is preferred LACTIC ACID – WHOLE BLOOD (NOT ON ICE) GRAY Sodium Fluoride Potassium Oxalate 8 tube inversions ensure proper mixing of additives with blood NO CLOTTING TIME REQUIRED LACTIC ACID (ON ICE) PURPLE Spray-coated K2EDTA (plastic) 8 tube inversions required to ensure mixing of anticoagulant with blood
Blood Collection Tube (Vacutainer) Types - MyHematology Immediately after collection, the blood tube must be gently inverted several times (typically 5-10 times, or as per manufacturer instructions) to ensure thorough mixing of the blood with the heparin This is vital to prevent any localized clotting
The Importance Of Shaking The Gray Top Tube During Blood Collection In addition to ensuring proper mixing of the additive, shaking the gray top tube during blood collection helps to prevent clot formation in the sample Clot formation can occur when blood cells clump together and obstruct the flow of the sample through the collection tube and testing equipment
Blood Collection and Handling - Edward-Elmhurst Health Mix Immediately after collection, gently mix the blood with the tube additive by inverting 8-10 times Avoid hemolysis of the specimen during collection and mixing Place the specimen in a rack at room temperature and centrifuge within 2 hours of collection Do not refrigerate the sample until the plasma is separated from the cells
Phlebotomy Tubes Explained - E Phlebotomy Training For adequate mixing of blood and additive, the tube must be inverted 4 to 5 times after specimen is collected Generally, phlebotomy tubes with gray stoppers are used to test glucose levels, lactate, bicarbonate and blood alcohol levels

Common blood collection tubes, their additives and laboratory uses Most blood collection tubes contain an additive that either accelerates clotting of the blood (clot activator) or prevents the blood from clotting (anticoagulant) The list below lists the most commonly used blood collection tubes, their additives and uses in laboratory:
Specimen Collection Tubes - Quest Diagnostics Glass serum tubes are recommend-ed for blood banking Plastic tubes contain clot activator and are not recommended for blood banking Inversions ensure mixing of clot activator with blood and clotting within 30-60 minutes For plasma determinations in chemistry Inversions prevent clotting
