Summary
- Each color tube is used for specific blood tests to prevent Cross-Contamination and ensure accurate results.
- Understanding the color codes for lab tubes is crucial for phlebotomists and healthcare professionals to effectively collect and transport blood samples.
- The color-coded system for lab tubes in the United States helps streamline the testing process and improve patient care.
Introduction
Phlebotomy, the practice of drawing blood from patients for diagnostic testing, is an essential component of healthcare delivery. To ensure accurate and reliable results, phlebotomists use color-coded tubes to collect blood samples for various laboratory tests. These color codes help prevent Cross-Contamination and ensure that the right tests are conducted on the right samples. In the United States, specific color codes are followed for lab tubes used in phlebotomy, each corresponding to different types of blood tests. Understanding these color codes is crucial for healthcare professionals to effectively collect and transport blood samples for analysis.
Why Color Codes Matter
Color codes for lab tubes in phlebotomy serve several important purposes:
- Prevent Cross-Contamination: Using different colored tubes for different tests helps prevent mixing of samples, reducing the risk of inaccurate results.
- Streamline the testing process: Phlebotomists can easily identify which tubes are needed for specific tests, streamlining the collection and processing of blood samples.
- Ensure accurate results: Each color tube is designed for specific types of tests, ensuring that the right tests are conducted on the right samples for accurate diagnostic results.
Specific Color Codes for Lab Tubes

Red Tubes
Red tubes are used for blood bank testing and serum chemistry. They do not contain any additives, making them suitable for tests that require serum samples.
Gold or Tiger Stripe Tubes
Gold or tiger stripe tubes are used for chemistry tests requiring serum samples, including basic metabolic panels and liver function tests.
Light Blue Tubes
Light blue tubes contain Sodium Citrate and are used for coagulation tests, such as PT/INR and aPTT.
Green Tubes
Green tubes contain Heparin and are used for plasma determinations in chemistry testing.
Lavender or Purple Tubes
Lavender or purple tubes contain EDTA and are used for hematology tests, including CBC and blood typing.
Gray Tubes
Gray tubes contain Potassium Oxalate and Sodium Fluoride and are used for glucose testing.
Light Green Tubes
Light green tubes contain lithium or sodium Heparin and are used for plasma determinations in chemistry testing.
Pink Tubes
Pink tubes are used for blood bank testing, including blood typing.
Yellow Tubes
Yellow tubes contain ACD or SPS and are used for blood cultures.
Final Thoughts
Understanding the specific color codes for lab tubes used in phlebotomy is essential for healthcare professionals to collect and transport blood samples accurately and efficiently. By following the color-coded system in the United States, phlebotomists can ensure that the right tests are conducted on the right samples, leading to improved patient care and diagnostic accuracy.
