The Importance of Order of Draw for Blood Collection Tube Colors
Proper blood collection techniques are essential in healthcare settings to ensure accurate Test Results and maintain patient safety. The order of draw for blood collection tubes plays a critical role in preventing contamination and ensuring the quality of specimens. When healthcare professionals draw blood for multiple tests, they must follow a specific sequence to prevent Cross-Contamination between different tube additives and ensure the accuracy of Test Results.
Common Order of Draw for Blood Collection Tube Colors
In the United States, healthcare professionals typically follow a specific order of draw for blood collection tube colors to minimize the risk of contamination and ensure the accuracy of laboratory Test Results. The most common order of draw for blood collection tubes includes the following sequence:
- Yellow - Blood Culture tubes
- Light Blue - Coagulation tubes, including tests such as PT/INR and PTT
- Red - Serum tubes for chemistry tests
- Tiger Top/Gold - Serum separator tubes for chemistry tests
- Light Green - Plasma tubes for chemistry tests
- Lavender - EDTA tubes for hematology tests
- Gray - Glucose tubes
- Royal Blue - Trace element tubes for heavy metal testing
Tests Associated with Each Blood Collection Tube Color
Each color-coded blood collection tube is designed for specific types of tests, and healthcare professionals must follow the correct order of draw to prevent contamination and ensure the accuracy of Test Results. Here is a list of common tests associated with each blood collection tube color:
Yellow - Blood Culture Tubes
- Blood cultures to detect the presence of bacteria or fungi in the bloodstream
- Septicemia and other blood infections
Light Blue - Coagulation Tubes
- Prothrombin Time (PT)
- International Normalized Ratio (INR)
- Partial Thromboplastin Time (PTT)
Red - Serum Tubes
- Basic metabolic panel (BMP)
- Comprehensive metabolic panel (CMP)
- Lipid panel
Tiger Top/Gold - Serum Separator Tubes
- Chemistry tests, including glucose, electrolytes, and liver function tests
- Complete Blood Count (CBC)
Light Green - Plasma Tubes
- Chemistry tests, including tests for ammonia, carboxyhemoglobin, and plasma protein
- Immunohematology (blood bank) tests
Lavender - EDTA Tubes
- Complete Blood Count (CBC)
- Blood typing and crossmatching for transfusions
Gray - Glucose Tubes
- Glucose tolerance tests
- Lactic acid measurements
Royal Blue - Trace Element Tubes
- Heavy metal testing, such as lead, mercury, and arsenic
- Toxicology screens
By following the correct order of draw for blood collection tube colors and understanding the tests associated with each tube, healthcare professionals can ensure the accuracy and reliability of laboratory Test Results. Adhering to standardized protocols for blood collection helps prevent errors, improve patient care, and maintain the integrity of the healthcare system.
