Lavender-top tubes (containing EDTA as an anticoagulant) are generally used for hematology testing to prevent coagulation and preserve cell morphology.
The stoppers of vacutainer tubes are color-coded to indicate the type of additive or anticoagulant in the tube. This helps healthcare professionals select the appropriate tube for specific blood tests, ensuring accurate and reliable results.
The yellow tube (sterile) should be filled first when drawing blood using the Vacutainer method. It is crucial to follow the recommended order to prevent contamination of samples and ensure accurate test results.

Phlebotomy is the department of medicine that is responsible for blood draws and using the right tubes to send blood off for testing. The Lavender tube is used for a CBC test, the RPR test is the red/gold tube and the basic metabolic test is also in the red gold tube.
Gray top tubes with sodium fluoride/potassium oxalate additive should not be spun in the centrifuge as it can alter test results by causing hemolysis. These tubes are usually used for glucose testing and need to be kept upright to prevent mixing with cells.

The Clinical and Laboratory Standards Institute (CLSI) recommends the order of draw as: 1) Blood culture tubes, 2) Coagulation tubes, 3) Serum tubes, 4) Heparin tubes (plasma), 5) EDTA tubes. The Association of Phlebotomy Technicians (ASPT) follows a similar order with minor variations depending on the institution's protocol. It's important to follow the specific guidelines of the facility where you are working to ensure accuracy and prevent sample contamination.
For a blood chemistry test, commonly a lavender-top (EDTA) vacutainer tube is used. These tubes are used to collect whole blood samples for testing electrolytes, metabolites, and other chemical components in the blood.
The proper order of draw for a syringe method is: Blood culture tubes Coagulation tubes Serum tubes Heparin tubes EDTA tubes Glycolysis inhibitor tubes
The first generation of electronic computers were those implemented using vacuum tubes.
