Summary

  • Phlebotomy tubes are essential tools used in healthcare settings to collect blood samples for diagnostic testing.
  • There are various types of phlebotomy tubes, each color-coded to indicate the specific tests they are used for.
  • Understanding the different types of phlebotomy tubes and their corresponding tests is crucial for accurate specimen collection and laboratory analysis.

Introduction

Phlebotomy tubes are a vital component of the healthcare system, used to collect blood samples for various Diagnostic Tests. These tubes come in different colors, each corresponding to a specific type of test to be conducted on the blood sample. In the United States, there is a standardized color-coding system for phlebotomy tubes, making it easier for healthcare professionals to identify the appropriate tube for each test. In this article, we will explore the different types of phlebotomy tubes used in the United States and the corresponding tests they are used for according to the phlebotomy tubes and tests chart.

Types of Phlebotomy Tubes and Corresponding Tests

Red-Top Tubes

Red-top tubes are commonly used for routine blood tests, such as complete blood count (CBC), blood typing, and cholesterol levels. These tubes do not contain any additives and are used for serum collection.

Blue-Top Tubes

Blue-top tubes are used for coagulation tests, such as Prothrombin Time (PT) and Activated Partial Thromboplastin Time (APTT). These tubes contain Sodium Citrate as an Anticoagulant to prevent blood clotting.

Green-Top Tubes

Green-top tubes are used for tests that require plasma, such as electrolyte panels and basic metabolic panels. These tubes contain Heparin as an Anticoagulant to prevent blood clotting.

Lavender-Top Tubes

Lavender-top tubes are used for hematology tests, such as complete blood count (CBC) and erythrocyte sedimentation rate (ESR). These tubes contain EDTA as an Anticoagulant to preserve blood cell morphology.

Gray-Top Tubes

Gray-top tubes are used for glucose testing, such as Fasting Blood Glucose and oral glucose tolerance tests. These tubes contain Sodium Fluoride as a preservative to inhibit glycolysis.

Yellow-Top Tubes

Yellow-top tubes are used for Blood Culture tests to detect the presence of bacteria or fungi in the bloodstream. These tubes contain SPS (sodium polyanethol sulfonate) as an Anticoagulant and a Blood Culture preservative.

Gold-Top Tubes

Gold-top tubes are used for various chemistry tests, such as liver function tests and renal function tests. These tubes contain a gel separator to separate serum from the clot after centrifugation.

Tiger-Top Tubes

Tiger-top tubes, also known as serum separator tubes, are used for chemistry tests that require serum, such as glucose, cholesterol, and electrolyte levels. These tubes contain a gel separator and Clot Activator to facilitate serum separation.

Pink-Top Tubes

Pink-top tubes are used for blood bank testing, such as blood grouping and cross-matching. These tubes contain EDTA as an Anticoagulant and are specifically designed for blood bank use.

Conclusion

Phlebotomy tubes play a crucial role in the healthcare system by allowing healthcare professionals to collect blood samples for diagnostic testing. Understanding the different types of phlebotomy tubes and their corresponding tests is essential for accurate specimen collection and laboratory analysis. By following the standardized color-coding system for phlebotomy tubes in the United States, healthcare professionals can ensure that the right tube is used for each test, leading to reliable and accurate Test Results.
