Introduction

In the field of veterinary medicine, accurate blood collection and testing are crucial for diagnosing and treating animals. Veterinary blood tubes are essential tools used in medical lab settings to safely collect and preserve blood samples for analysis. Different types of blood tubes are available, each serving specific purposes in phlebotomy procedures. In this article, we will explore the various types of veterinary blood tubes commonly used in the United States and their specific uses in veterinary care.

Types of Veterinary Blood Tubes

1. EDTA Tubes

EDTA tubes, or ethylenediaminetetraacetic acid tubes, are commonly used in veterinary medicine for collecting blood samples for hematology tests. These tubes contain an anticoagulant, EDTA, which prevents blood clotting by chelating calcium ions. EDTA tubes are typically lavender or purple in color and are used for collecting whole blood samples for tests such as complete blood count (CBC) and blood smear evaluations.

2. Serum Separator Tubes

Serum separator tubes, also known as SST tubes, are used to collect blood samples for serum chemistry tests. These tubes contain a gel separator that forms a barrier between the serum and the clot after centrifugation, allowing for easy separation of serum for analysis. SST tubes are typically red or gold in color and are used for tests such as liver function tests, kidney function tests, and electrolyte panels.

3. Heparin Tubes

Heparin tubes are coated with lithium Heparin or sodium Heparin and are used for collecting blood samples for various chemistry tests that require plasma rather than serum. Heparin acts as an Anticoagulant by inhibiting thrombin and preventing blood clot formation. Heparin tubes are typically green in color and are used for tests such as blood gas analysis, cardiac markers, and Therapeutic Drug Monitoring.

4. Citrate Tubes

Citrate tubes, or blue tubes, contain Sodium Citrate as an Anticoagulant and are used for coagulation studies in veterinary medicine. Citrate binds calcium ions, preventing blood clotting by inhibiting the coagulation cascade. Citrate tubes are used for tests such as Prothrombin Time (PT), Activated Partial Thromboplastin Time (aPTT), and Fibrinogen Assays.

Specific Uses in Phlebotomy Procedures

1. EDTA Tubes: Used for hematology tests such as complete blood count (CBC) and blood smear evaluations.
2. Serum Separator Tubes: Used for serum chemistry tests such as liver function tests, kidney function tests, and electrolyte panels.
3. Heparin Tubes: Used for chemistry tests that require plasma rather than serum, such as blood gas analysis, cardiac markers, and Therapeutic Drug Monitoring.
4. Citrate Tubes: Used for coagulation studies such as Prothrombin Time (PT), Activated Partial Thromboplastin Time (aPTT), and Fibrinogen Assays.

Importance of Accurate Blood Collection and Testing

Accurate blood collection and testing are essential in veterinary care for diagnosing and monitoring various health conditions in animals. The use of appropriate veterinary blood tubes ensures that blood samples are properly collected, preserved, and analyzed for accurate and reliable results. Proper handling of blood tubes, correct filling volumes, and timely processing of samples are critical steps in phlebotomy procedures to avoid hemolysis or contamination that can affect Test Results. By understanding the different types of veterinary blood tubes and their specific uses in phlebotomy procedures, veterinary professionals can ensure high-quality care and treatment for animals.
