The three tubes that contain plasma are the red-top tube, green-top tube, and lavender-top tube. Plasma is the liquid component of blood that does not contain cells and is obtained by spinning down a blood sample in the presence of an anticoagulant.
The order of draw for blood collection tubes typically starts with tubes that do not contain additives, such as the red top tube for serum samples. This is followed by tubes with specific additives for various tests, such as anticoagulants like EDTA or citrate for plasma samples. The specific order may vary depending on the facility's protocol.
Blood for a Basic Metabolic Panel (BMP) or Sequential Multiple Analysis (SMA) test is typically drawn into a green or red-topped tube. Green top tubes typically contain lithium heparin as an anticoagulant, while red top tubes do not contain any anticoagulant.
The color of the tube used for collecting a basic metabolic panel is typically green or lavender. Green-top tubes are used for plasma collection, while lavender-top tubes are used for whole blood collection containing an anticoagulant. Either tube can be used depending on the laboratory's preference.
The order of draw would be the red top first, the green top second, and last would be the lavender top
Typically, a red-top or green-top tube is used to collect blood for a digoxin level test. The blood sample is collected through a venipuncture procedure, and the tubes contain no anticoagulant. It's important to follow standard blood collection procedures and handle the sample with care to ensure accurate test results.
The blood tube color for lactate testing is typically a green or light green top tube, which contains sodium or lithium heparin as an anticoagulant. These tubes are used to prevent clotting of the blood sample during testing for lactate levels.
A CK blood draw typically goes into a red-top tube.
The Clinical and Laboratory Standards Institute (CLSI) and the American Society for Clinical Pathology (ASCP) recommend a specific order of draw to prevent cross-contamination of samples. The general order is as follows: blood culture bottles, light blue top (sodium citrate), red top (serum), gold or tiger top (serum separator), green top (heparin), lavender top (EDTA), and gray top (glycolytic inhibitor). Following this order ensures that additives in the collection tubes do not interfere with test results. Always refer to the latest guidelines for any updates or specific protocols.
