Introduction

Phlebotomy, the practice of drawing blood from patients, is an essential component of healthcare services. Phlebotomy tubes are used to collect and store blood specimens for diagnostic testing in clinical labs and hospitals. These tubes come in different colors, each representing a specific additive or preservative that helps maintain the quality of the blood sample. In the United States, various phlebotomy tube colors are used to ensure accurate Test Results and proper patient care.

Common Phlebotomy Tube Colors

There are several common phlebotomy tube colors used in the United States, each serving a specific purpose in blood collection and testing. Here are some of the most common tube colors and their significance:

Red Tubes

1. Red tubes are typically used for routine blood tests, such as chemistry panels, lipid profiles, and blood bank studies.
2. The tubes may contain a Clot Activator and gel separator to separate serum from the clot after centrifugation.

Green Tubes

1. Green tubes are used for tests that require plasma, such as chemistry tests, STAT chemistry tests, and Therapeutic Drug Monitoring.
2. The tubes contain sodium Heparin as an Anticoagulant to prevent blood clotting.

Lavender Tubes

1. Lavender tubes are used for hematology tests, such as complete blood counts (CBC) and erythrocyte sedimentation rate (ESR) tests.
2. The tubes contain EDTA (ethylenediaminetetraacetic acid) as an anticoagulant.

Blue Tubes

1. Blue tubes are used for coagulation tests, such as Prothrombin Time (PT), Activated Partial Thromboplastin Time (aPTT), and D-dimer tests.
2. The tubes contain Sodium Citrate as an anticoagulant.

Gray Tubes

1. Gray tubes are used for glucose testing, such as Fasting Blood Glucose and oral glucose tolerance tests.
2. The tubes contain Sodium Fluoride as a glycolysis inhibitor and Potassium Oxalate as an anticoagulant.

Additional Phlebotomy Tube Colors

In addition to the common tube colors mentioned above, there are several other phlebotomy tube colors used in the United States for specific tests and purposes. These colors may vary depending on the manufacturer, but they all serve a vital role in blood collection and testing:

Yellow Tubes

1. Yellow tubes are used for blood cultures to detect bacterial infections.
2. The tubes contain SPS (sodium polyanethol sulfonate) as an Anticoagulant and preservative.

Black Tubes

1. Black tubes are used for tests that require whole blood, such as sedimentation rate tests.
2. The tubes contain EDTA as an anticoagulant.

White Tubes

1. White tubes are used for molecular Diagnostic Tests, such as DNA testing and PCR (polymerase chain reaction) tests.
2. The tubes contain EDTA as an anticoagulant.

Orange Tubes

1. Orange tubes are used for tests that require serum or plasma, such as immunology and serology tests.
2. The tubes may contain Clot Activator and gel separator.

Pink Tubes

1. Pink tubes are used for blood banking, blood typing, and cross-matching tests.
2. The tubes contain EDTA as an anticoagulant.

Conclusion

Understanding the different phlebotomy tube colors is crucial for healthcare professionals involved in blood collection and testing. Each color represents a specific additive or preservative that helps maintain the integrity of the blood sample and ensures accurate Test Results. By using the right tube color for each test, Healthcare Providers can provide quality care to patients and contribute to the overall efficiency of clinical labs and hospitals in the United States.
