What You'll Learn
Tube colors and additives is a crucial topic for the Phlebotomy Certification exam, as it covers the proper selection and use of different types of blood collection tubes. Understanding the purpose and characteristics of each tube type is essential for phlebotomists to ensure accurate and reliable sample collection and analysis. This topic examines the various tube colors, their associated anticoagulants or additives, and the appropriate uses for each type of tube.
Key Concepts
Tube Colors
Blood collection tubes come in a variety of colors, each representing a specific type of additive or anticoagulant. Common tube colors include red, gold, green, lavender, blue, gray, and yellow, among others.
Anticoagulants
Anticoagulants are substances added to blood collection tubes to prevent the blood from clotting. Examples include EDTA (purple/lavender tube), heparin (green tube), and sodium citrate (light blue tube).
Tube Additives
In addition to anticoagulants, some tubes may contain other additives, such as clot activators (red/gold tube), gel separators (gold tube), or preservatives (gray tube). These additives help prepare the sample for specific testing or analysis.
Tube Selection
Phlebotomists must select the appropriate tube based on the specific test or analysis required. Choosing the wrong tube can result in inaccurate results or even the need to recollect the sample.
Order of Draw
When collecting multiple tubes, it is crucial to follow the proper order of draw to prevent cross-contamination between tubes and ensure the integrity of the samples.
Common Mistakes to Avoid
- Mixing up the color coding of different tube types
- Failing to properly mix the blood with the additive after collection
- Neglecting to fill the tubes to the appropriate volume
- Collecting samples in the wrong order, leading to cross-contamination
- Using the wrong tube type for a specific test or analysis
