Blood collection is a critical step in medical diagnostics. The use of a Blood-Collection-Tube is essential to ensure the integrity and accuracy of laboratory results. Different colored tubes are used for various types of tests, and understanding the significance of these colors is crucial for healthcare professionals. In this article, we will delve into the specifics of blood collection tubes, their colors, and their designated purposes, providing a comprehensive guide for both beginners and seasoned medical workers.
A Blood-Collection-Tube is a sterile container used to collect blood samples for laboratory testing. Each tube is usually equipped with a specific additive that helps preserve the sample or prepares it for a particular type of analysis. The color of the tube cap indicates the type of additive inside, thus signaling its intended use.
The system of color coding for blood collection tubes has been standardized internationally, making it easier for professionals worldwide to recognize and use the right tube for each diagnostic test.
For instance, a lavender-top tube typically contains EDTA, an anticoagulant used for complete blood counts (CBC), while a red-top tube contains no additives and is used for serum tests. Choosing the right Blood-Collection-Tube is crucial because the wrong additive can interfere with test results, leading to inaccurate diagnoses.
Let's explore some of the most common blood collection tube colors and their purposes:
Red Top: No additive; used for serum collection in chemistry and serology testing.
Gold or Yellow Top (SST): Contains a clot activator and gel for serum separation.
Light Blue Top: Contains sodium citrate; used for coagulation studies like PT and APTT.
Green Top: Contains heparin; used for plasma determinations in chemistry.
Lavender or Purple Top: Contains EDTA; ideal for hematology tests.
Gray Top: Contains potassium oxalate and sodium fluoride; used for glucose and lactate testing.
Understanding these differences helps healthcare workers to ensure that blood samples are collected in the appropriate Blood-Collection-Tube for the required laboratory tests.
Choosing the correct Blood-Collection-Tube is not just a matter of routine—it directly impacts the quality of the test results. Each additive interacts differently with blood components:
Clot activators help in obtaining serum by facilitating blood clotting.
Anticoagulants such as EDTA, citrate, or heparin prevent clotting and preserve various blood constituents.
Gel separators in SST tubes form a barrier between serum/plasma and blood cells after centrifugation, maintaining sample purity.
Using an incorrect tube can cause hemolysis, clotting, or chemical interference, potentially leading to wrong diagnoses or the need for repeat sampling, which is uncomfortable for the patient and costly for healthcare providers.

Here are some practical guidelines for healthcare practitioners:
Verify Tube Labeling: Always check the label for the correct additive before use.
Follow Proper Order of Draw: To avoid cross-contamination of additives between tubes, use the recommended order of draw.
Handle with Care: Shake tubes gently (if required) to mix additives without causing hemolysis.
Store Appropriately: Store tubes in a cool, dry place to maintain vacuum and additive integrity.
Proper handling of a Blood-Collection-Tube ensures accurate lab results and enhances patient safety.
Understanding the different colors and uses of Blood-Collection-Tube systems is vital for ensuring the accuracy of laboratory testing.
