3. Heparin Tubes: These tubes contain the Anticoagulant Heparin and are used for testing plasma samples.
4. Sodium Citrate Tubes: These tubes contain the Anticoagulant Sodium Citrate and are used for coagulation studies.

How to Use Venous Blood Collection Tubes

Properly using venous blood collection tubes is essential to ensure accurate Test Results and patient safety. Here are some key steps to follow when using venous blood collection tubes in phlebotomy:

1. Identify the correct venous blood collection tube based on the type of test being performed.
