• Blue Top Tubes: Known as sodium citrate tubes, these contain a citrate additive that prevents blood from clotting. They are primarily used for coagulation studies.
• Green Top Tubes: These tubes contain heparin and are used for plasma collection. They are often called heparin tubes and are common in tests requiring plasma samples.
• Lavender (or Purple) Top Tubes: Containing EDTA as an anticoagulant, lavender top tubes are used for complete blood counts (CBC) and blood smears.
• Grey Top Tubes: These tubes contain additives such as sodium fluoride and potassium oxalate, which prevent glycolysis. They are often utilized for glucose testing.
• Gold Top Tubes: Also known as serum separator tubes (SST), they contain a gel that separates serum from other components of the blood after centrifugation.

Understanding Additives in Blood Collection Tubes

The role of additives in blood collection tubes is significant, as they determine the tube's suitability for specific tests. Here's a brief breakdown of some crucial additives and their function:

• Sodium Citrate: Anticoagulant that prevents clotting and is essential for coagulation tests.
• EDTA: A strong anticoagulant that preserves the shape of blood cells for accurate microscopic examination.
• Heparin: Another anticoagulant that is commonly used in plasma sample tests.
• Sodium Fluoride: Preserves glucose levels for accurate measurement in glucose tests.

Choosing the Right Blood Collection Tube

Selecting the appropriate blood collection tube is crucial for obtaining accurate test results. Factors influencing the choice of tube include:

• The specific tests being ordered by the healthcare provider.
