Overview of Special Evacuated Blood Collection Tubes

Special Evacuated Blood Collection Tubes are specifically designed to facilitate the collection and preservation of blood samples for various laboratory tests. These tubes have a vacuum that allows for a quick and efficient draw of blood without the risk of contamination. They come in various colors, each indicating different additives, which serve distinct purposes.

Types of Special Evacuated Blood Collection Tubes

There are several types of Special Evacuated Blood Collection Tubes, and each type is color-coded based on the additive inside. Here are the most common types:

• Red Tube: Contains no additives and is used for serum tests.
• Gold Tube: Contains a gel separator and is suitable forserum testing—ideal for biochemistry tests.
• Light Blue Tube: Contains sodium citrate and is used for coagulation studies.
• Green Tube: Contains heparin and is effective for plasma chemistry tests.
• Lavender Tube: Contains EDTA, which is primarily used for complete blood counts (CBC) and blood smears.
• Gray Tube: Contains sodium fluoride and is used for glucose testing.

Importance of Proper Tube Selection

Choosing the correct type of Special Evacuated Blood Collection Tubes is essential for obtaining accurate test results. Using the wrong tube can lead to contamination or insufficient sample volume, resulting in inconclusive or erroneous test outcomes. Therefore, lab personnel must be trained to recognize the various tubes and their appropriate applications.
